Keynote Lecture
Geomatics in Disaster Risk Management

In recent years, due to an increasing number of natural and manmade disasters, mainly related to climate change, a growing attention is paid to geomatics techniques when used for emergency management applications. This is essentially due to the large availability of different types of remotely acquired imageries and georeferenced data, allowing the extraction of relevant information, useful to approach, in an operational way, the different disaster cycle phase.

In this kind of application, different crucial issues should be taken into account:

• Timeliness of the service, in order to guarantee the fast provision of raw and thematic data (both raster and vector);
• The necessity to set up consolidated procedures allowing the delivery of consistent and generalized products;
• The overall request to produce certified data, quality checked and stating, in the meantime, geometric and thematic accuracies;
• The necessity to define precise data model and all the set of metadata describing the data itself;
• The obligation to deliver such data (raw and thematic) using an interoperable schema, allowing maps multiple usage and/or re-usage, and avoiding redundancy and effort duplication.

All these constraints will be taken into account to describe the current and most operational approach to emergencies, and in particular in the field of:

• Early warning systems;
• Early impact procedures;
• Post Disaster Need Assessment (PDNA)
• Lesson learned and capacity building.

At the same time, particular attention will be paid to new operational services (both in early warning and impact stages), new data acquisition systems (satellite and aerial sensors, UAV, Mobile Mapping Systems – MMS) and to the new perspective related to the massive usage of open source data, crowdsourcing/crowdmapping, voluntary crisis mappers and social networks approach.

Keynote Lecture
Urban Landslides in the Pacific Northwest

Each year landslides cause 25-50 deaths and on the average $3.5 billion in damage in the United States. Many of these landslides occur in urban settings. Figuring out what caused these landslides and also how to prevent them can be a challenge to geologists. The talk will focus on lessons learned from Pacific Northwest case histories in urban settings, focusing on homes hit by landslides, homes that moved down the slope on landslides, reactivation of ancient landslides, triggers such as precipitation and earthquakes, and vacant lots. Development of susceptibility maps, especially using LiDAR imagery, will be included. Different mitigation methods including different types of dewatering devices, walls, and freezing of the soil will be mentioned. The importance of lack of insurance for landslides on normal homeowner policies has great significance.

Keynote Lecture
Key issues in rock fall risk assessment

Rock falling is a widely diffused type of slope instability causing high risk in many natural and artificial conditions. During the year many different approaches have been proposed to assess rock fall susceptibility, hazard, triggering and propagation. Nevertheless, the more advanced models and statistical approaches still have to face a highly indeterminate process in which small changes in variables can cause notable changes in results and effects. This lecture, even if limited to the experience of the author and collaborators, discusses the main problems linked to the type of phenomenon, the modelling approaches, the common need for delineation of hazard and risk zones.

Keynote Lecture
Using the Working Classification of Landslides to assess the danger from a natural slope

An essential input to any calculation of the stability of a natural slope is a hypothesis about how the slope may move. No formal method for estimating likely kinematic modes of slopes exists unless the slope is currently moving or has moved in the past. A working hypothesis is that similar slopes in similar materials move in similar modes in response to similar causes.

During the IDNDR(1990-2000), the IAEG Commission on Landslides contributed to the Working Classification which records an international consensus on types of landslides. A landslide can be typed by a term describing the natural materials before they were displaced and a second term describing the movement. Materials are rock, debris or earth; earth may be sand, silt or clay. Movements may be falls, flows, slides, spreads or topples.

Water conditions in the displaced material may range from dry thru' moist and wet to very wet. In permafrost terrain, frozen and thawed displaced material may occur. Water conditions, material and mode of movement may govern the rate of movement of the displacing mass. It can range from extremely slow to the extremely rapid movements which may have catastrophic impacts.

Activity, its distribution and style may affect anticipated modes of movement in assessed slopes. Slopes may be active suspended, reactivated, dormant, abandoned, stabilized, repaired, or relict. Styles of movement may be complex, composite, successive and multiple. Compilations of the historic activity of similar slopes as landslide inventories suggest hazard scenarios which can form plausible initial hypotheses for risk assessments.

Keynote Lecture
Underground Urban Development, an overview.

Use of underground space in cities has a long history and may span significant areas. Today, it contributes to finding solutions for sustainable urban development, in particular in regions with harsh climatic conditions. Underground urban development is mainly determined by economic, environmental, geo-technical and legislative factors. These factors are briefly addressed in this paper. In addition, underground urban development requires vision and leadership from (local) politicians. Special attention is given to China, where significant underground urban development is undertaken today. Finally, this paper discusses perspectives and challenges related to underground urban development with special emphasis upon the role of engineering geologists.

Keynote Lecture
Problems in buildings and public Works derived from soils with metastable structure and soils with large volume instability

Collapsible and swelling soils are responsible for producing large foundation movements, even in the absence of load changes. Their structure, degree of saturation, and loading history make them prone to important changes in void ratio as a result of changes in water content under constant construction loads. The resulting differential movement may cause severe damages to structures, especially when affecting to old constructions, some of them of high historical or architectural value.
Among different techniques that have been used to face those problems, the soil improvement and bolting, by means of systematic fracture grouting through steel sleeve-pipes, allows to stabilize the ground, even affected by superimposed problems of slope instability and karstic phenomena of high rate development (like in gypsiferous or other even more soluble soils) without any need of mechanical connection with the foundation structures themselves. The communication will mention a number of collapsible and swelling materials, identified in different countries all over the world, as well as some stabilizations, by means of fracture grouting, involving important problems of engineering geology, and high value historical and architectural sites, like the Alhambra and Generalife Monument, in Granada.

Keynote Lecture
Emerging global issues in river basin management: a geomorphic perspective 

For as long as people have been living next to and with rivers the fundamental challenges of managing rivers and river basins have remained approximately the same. These include providing human populations with clean, potable water and hydraulic energy, safely removing municipal, agricultural and industrial wastes, and protecting people and infrastructure from climatic and hydrologic extremes of flood and drought. But burgeoning populations, loss of critical ecosystems and biodiversity, dramatic shifts in land use and technologies, and the potential for rapidly accelerating climate change in the near future have recast these old problems in a new light, and new issues and questions are emerging that are pushing the limits of our technical understanding. For example, can dams and reservoirs be managed to mitigate the effects of changing climate on streamflow and sediment transport regimes? Can dense human populations co-exist in the same river basins with threatened and endangered aquatic species? Can river floodways be managed to reduce the risk of natural hazards while retaining river function? Can fluvial and ecological functions be restored or re-introduced into severely degraded river systems?
Drawing from these and other examples, I will argue that addressing these questions requires broadened interdisciplinary perspectives that integrate geomorphic and ecological principles into engineering designs.

Keynote Lecture
Towards improved landslide mapping and forecasting

Landslides are present in all continents, and play an important role in the evolution of landscapes. Despite the fact that slope failures are ubiquitous, we estimate that landslide maps cover less than 1% of the slopes in the landmasses, and systematic information on the type, abundance, and distribution of landslides is lacking. Preparing landslide maps is important to document the extent of landslide phenomena in a region, to investigate the distribution, types, pattern, recurrence, and statistics of slope failures, to determine landslide susceptibility, hazard, vulnerability and risk, and to study the evolution of landscapes dominated by mass-wasting processes. In many areas, landslides are a serious hazard. In Italy, a country for which detailed information exists, landslides have caused more than 5,000 fatalities between 1950 and 2013, and represent a leading cause of death due to natural hazards. In this country, and in many other areas, rainfall-induced landslides cause most of the landslide fatalities. For this reason, determining the amount of rainfall needed to trigger slope failures is a problem of both scientific and societal interest.
Modern techniques for the detection and mapping of event (e.g., fresh) landslides are presented. The focus is on techniques that exploit HR and VHR satellite images, including multiple-change-detection (MCD), Bayesian, and combined techniques. This is followed by a presentation of the results obtained on the definition of objective empirical rainfall thresholds for the possible occurrence of rainfall induced landslides, and on the evaluation of the uncertainty associated to the empirical thresholds. Lastly, the integration of the empirical thresholds in a prototype national-scale landslide warning system is illustrated. We designed and we operate the system for the Italian National Department for Civil Protection.

Keynote Lecture
Understanding the mechanism of large-scale landslides triggered by strong earthquakes in China

China is a country with complex tectonic background, especially in the southwest, where the collision between Indian and Europe-Asian plates caused the intensive uplift of the Tibetan Plateau, producing many active faults and high seismic activity. Due to high and sharply changing altitude, steep and rugged terrain, deeply incised valleys and fragile geoenvironment, strong earthquakes often triggered giant or large-scale landslides in the east margin of Tibet Plateau and the famous North-south tectonic belts. About ten landslides concentrated in different fault zones, such as the Haiyuan, Dadu and Wenchuan regions, were investigated in detail. In order to understand their failure mechanism, the in-situ seismography monitoring, shaking table tests and numerical simulation have been carried out. This keynote summarizes the main knowledge we gained from these case studies.
For rockslides, we found that the combination of strong and long-lasting ground shaking, steep, rugged topography and a fragile and densely jointed lithology probably controlled the occurrence of landslides during the earthquake, but other factors may have also played a role. The in-situ monitoring result reveals the slope response to seismic waves, showing that the sudden change of slope angle, narrow/thin mountain ridges and isolated hills etc. may play more crucial roles in the amplification of peak ground acceleration (PGA) than elevation. Generally, the amplification factor at high and sharply changing parts of mountains can be reached to 1.6-3.0. That means under strong earthquake, vertical and deep tension cracks would be favorably developed in the rear part of a slope and form a very steep back scarp. Further investigation helps us to set up a very typical conceptual model for SETL, which can be described as vertical tension cracking at the rear part of a slope and low angle shearing failure on the front part. That is the “L” –shaped slip surface to be quite different from general landslides under gravity force.
Different from rockslides in the Dadu and Wenchuan regions, landslides in Haiyuan region are developed in gentle loess slopes. These landslides are characterized by large volume, high speed and long runout. They also have rather low reach angle, only 5-10o, also called “apparent friction angle” (defined as the ratio between the vertical drop and the horizontal travel distance of a landslide). Our investigation of the loess landslides indicates that their failure is controlled by the intrinsic micro-structure of loess, including the high porosity and weak point-contact/bonding between particles. It is found that the earthquake vibration promotes the occurrence of loess landslides by means of 1) liquefying the saturated loess (normally silt-sized) so that the shear resistance gets largely reduced; and 2) breaking the bonding between particles, making a flow-like dispersed soil mass. Both favor a sudden failure of loess landslide with long runout.

Title: Extreme Events and Engineering Geology: Processes, Effects, and Contributions for Resilient Communities

Abstract: Engineering geologists are familiar with a variety of extreme events, ranging from those that are dramatic (great earthquakes, volcanic eruptions, and catastrophic landslides) to those that may be subtle (aquifer depletion or contamination, enhanced susceptibility to erosion resulting from drought or wildfire, coastal subsidence, and sea level rise). This workshop will provide a forum for engineering geologists to discuss experiences with some case histories of extreme events and the role of engineering geologists in characterizing a)the loads and forces that might be needed for improved design, b) opportunities for mitigating the effects on infrastructure, and c) the frequency and magnitude of the processes and the extent of damaging effects.

Engineering geology for cultural heritage conservation: the "size" of the problem and some achievements in UNESCO World Heritage Sites

Cultural heritage represents the legacy of the human kind on the planet earth. It is evidence of millennia of adaptation of humans to the environment. Cultural heritage can be intangible (e.g. traditional knowledge, customs, ritual practices or beliefs) and tangible, the latter including various categories of places, from cultural landscapes and sacred sites to archaeological complexes, individual architectural or artistic monuments and historic urban centres.
The above sites and remains are not always in equilibrium with the environment. They are continuously impacted and weathered by several internal and external factors, both natural and human-induced, with rapid and/or slow onset. These include major sudden natural hazards, such as earthquakes or extreme meteorological events, but also slow, cumulative processes such the erosion of rocks, compounded by the effect of climate change, without disregarding the role of humans, especially in conflict situations.
Against this background, engineering geology and earth science in general may play an essential role in the conservation and management of cultural properties. The relevance and potential of these areas of study was not fully appreciated in the past. At present, however, their contribution is increasingly acknowledged as the need for an inter-disciplinary approach, which would bring together art history, science, management and socio-economic concerns, has become more and more apparent.
In recent decades, many sites of significant cultural heritage value have suffered damage, occasionally irreversible, from natural and human-induced processes. This paper is presenting some case studies, in which the author has been directly involved, where engineering geology and earth science were applied in the context of programmes implemented by the United Nations Educational, Scientific and Cultural Organization (UNESCO) to protect and maintain important cultural heritage sites. The selected sites concentrate mainly in regions of the world recently involved in conflicts or requiring international assistance and cooperation due to the dimension of the disaster and the lack of local capacity.

Keynote Lecture
Engineering Geology for tunneling in difficult ground

The growth of infrastructure needs has increased the demands for the excavation of tunnels in poor ground or varying geological conditions. The assessment of ground for design has to be based on a sound understanding of the regional geological rules and on the establishment of a geological model where data and conditions are translated into an engineering geology description. Examples of geological models and cases from both mountain and urban tunnels under complex or difficult geological conditions are presented.
Tunnel design requires knowledge on the quality of the material in which the tunnel will be constructed. Engineering design requires numbers and the lecture explores and discusses methods that can be used by engineering geologists to assess the geological factors that have an impact on the design. Since the attempt of Terzaghi, in 1946, to describe the characteristics of rock masses, a number of rock mass classifications have been developed and play an important role in tunnel design and in providing input data on strength and deformation properties of the ground for numerical models. A discussion on this issue is presented. Together with the rock mass properties, the in situ stresses field has to be estimated or measured and this is one of the most difficult tasks.
Although the role of engineering geology has been extended into the area of defining the design parameters, the idealization process, in the form of numerical analysis, should be driven by sound geologic reasoning together with the engineering logic.
The understanding of real behaviour is indeed absolutely necessary before any calculation is attempted. Thus, the engineering geological “I.D” of the geomaterial and the stress environment define this ground behaviour such us:
• Brittle failure of strong massive rock under high stress level.
• Gravitational falling or sliding of blocks or wedges defined by intersecting structural features or “chimney” type failure, or ravelling in disintegrated and heavily broken and loose masses.
• Formation of a “plastic” zone by shear failure under high stress relative to the strength of the rock mass with deformation problems or even squeezing.
• Swelling, in case of appropriate mineralogical constitution.
The lecture discusses also cases as slope tunnels, interaction in twin tunnels, and tunneling in rock masses with expressed anisotropy, while examples from a number of tunnels from around the world illustrate the design and construction procedures is presented.

Optimization of Large Civil Engineering Projects from the Environmental point of view

Without exception, the construction and operation of civil engineering projects have resultant environmental impacts.
However, in most cases the projects are essential to the economic and social development of the regions where they are located and for some, their sole purpose is to protect people and goods from natural hazards such as floods and landslides.
In general, the media and environmentalists tend to enhance the negative impacts of the projects and very seldom make reference to their positive impacts.
In this context, the need for high quality studies and designs is assuming increasing relevance for engineering projects, to ensure solutions with the least negative impacts are selected and subsequently constructed and operated by suitably qualified staff.
The role of geotechnics in the optimization of civil engineering projects is therefore as important as is the efficient and early intervention of specialists, and their decisions, on the technical, economic, social, environmental and operational aspects of the works.
To illustrate that it is often possible to optimize projects from an environmental point of view, several examples are presented in relation to construction materials, hydraulic developments, linear works (roads, railways, airways, and waterways), underground works, maritime works, bridges and viaducts, and natural and excavation slopes. In each case, emphasis is placed on the environmental concerns that require optimization of the design in order to minimise the negative impacts without diminishing the economic and social benefits of the works.

Keynote Lecture
Large-Scale Thematic Geological Mapping of Megacities (by the example of Moscow)

An ambitious research project was implemented at the Sergeev Institute of Environmental Geoscience of the Russian Academy of Sciences in collaboration with the Moscow Geological and Geodetic Trust during 2008-2009 according to the decision of the Moscow Government. The project implied the compilation of 12 thematic geological large-scale maps for the Moscow territory to a scale 1 : 10 000. This work was based on the digital processing of more than 85 000 boreholes drilled in the city in different years, among which 13000 deep boreholes penetrated in the Carboniferous deposits. This is a pioneer work in Russia, because apart from the digitizing and analysis of a great volume of drilling data, it implied theoretical and methodical studies based on modern geoinformational techniques. The resultant combined map of engineering geological zoning was based on the integration of data on the structural-geodynamic, geomorphological and geological structure, hydrogeological conditions, distribution of natural hazards and geological processes and phenomena. The map proceeds from the principle of consistent typological division of the territory into four taxonomic levels, using the index method naming of taxa of different rank. The performed complex analysis of engineering geological conditions permitted us to distinguish three degrees of complexity for construction, which should be taken into account at the early stages of designing subsurface and surface urban engineering structures

Translating Geotechnical Risk in Financial Terms

Practitioners know that geotechnical uncertainty never ends until a tunnel is completed. In some cases, uncertainty extends into operation. The present note summarizes relevant project financing elements such as viability, risk allocation, and bankability. Main financial instruments for different project structures are outlined, highlighting their likely ranges of application. Two key instruments for managing project risks, the Geotechnical Baseline Report, and the Project Risk Register, are presented and their joint use illustrated. The importance of carrying over uncertainty along the entire project cycle (planning, construction, and operation) is elaborated by using a concept borrowed from the hydropower sector.

Keynote Lecture
Continuous observation, modelling and model checking: setting adequate models to tackle natural risks (is there a better way to fully exploit the expertise of geologists and engineers at the same time?)

Recent times have shown a continuous increase of the risk due to both natural and anthropogenic hazards. This is mostly a consequence of the increase in exposure due to the growth of the population and of the land use, especially in developing countries. In the most advanced countries the exposure to risks is less acceptable because of the higher culture and sensibility of people which are more and more security-conscious and demand for more protection. The situation is then highly charged and urge the development of effective criteria for risk mitigation. This requires a clear knowledge of the phenomena in hand.
The paper reports the present knowledge on the characteristics of flow-like landslides, the most destructive events induced by slope failure, with special reference to those that involve saturated silty and clayey soils. Mostly based on Italian experience, it describes the recent growth of the knowledge thanks to the close relationship that researchers have capable to establish between experience and theory. While experience provides data and observations, theory elaborates and explains experimental data within a conceptual frame. This approach can be continued still more: in fact, the integration between further experiments and the use of advanced modelling can contribute in the development of new and even more effective theoretical tools. This can be more easily and effectively obtained through the work carried out by people having a different background, as geologists and engineers, who can deeply integrate their own experience and knowledge.

Keynote Lecture
Assessing climate change risks under uncertain conditions

Climate and environmental change is expected to potentially affect hydrometeorological hazard and ecosystem functioning, with possible threats to human societies due to an increased probability of extreme events and a loss of ecosystem services. In mountain regions, the environmental response could be even larger. For this reason, it is essential to obtain estimates of the expected modifications in natural hazards associated with climate and environmental change, to develop appropriate adaptation and risk mitigation strategies. This goal, however, is made difficult by the scale mismatch between climate model projections and land surface response, which requires the use of appropriate climate downscaling procedures. To complicate the picture, one should also cope with the chain of uncertainties which affect climate and risk projections, from the wide range of global climate model estimates for the water cycle variables, to the uncertainties in regional climate response, to the uncertainties in the hydrological and/or ecosystem models themselves. Precipitation data used to validate the models, on the other hand, are also affected by severe uncertainties, especially in mountain regions. In this talk, I shall address some of these issues and discuss the problem of assessing natural hazards for the different climate and environmental change scenarios under uncertain conditions.

The challenges of an Engineering Geologists in the digital era of communication

How engineering geologists present data, information and expert knowledge, to an ever increasing variety of stakeholders, is a continual challenge. In the last twenty-five years, information technology and increased computing capacities have transformed the way in which engineering geologists and geoscientists work. In particular, the development and use of Geographical Information Systems (GIS) and modelling packages have meant that there is now a far greater opportunity to develop engineering geological products that show more effectively the third-dimension (3D) and now increasingly spatially monitor temporal data in four-dimensions (4D) . With the increasing speed of development of information technology and computing capacities for visualising ground investigation information and geological knowledge it is important for engineering geologists to keep knowledge and expertise up to date. Training and continual professional development is vital, as well as the development of standards and best practice to ensure consistency and interoperability of data.
These tools are for the first time enabling geologists and engineering geologists to create and communicate, interactively, 3D geological and engineering geological models that were previously developed as two-dimensional images (maps and cross-sections) by combining ground investigation information and geological knowledge. These tools have also opened up the question of how to deal with uncertainty and spatial variability. Various techniques are now being advanced looking at both deterministic and probabilistic approaches to answer these questions. This is now a key research challenge for engineering geology.

Keynote Lecture
Landslide Risk Assessment at Cultural Heritage Sites

Cultural heritages such as castles, palaces, monasteries, temples and other important human buildings have been constructed in chosen stable areas and those have survived for long years.
Some of cultural heritages are constructed on slopes, at the head of slopes or the flat ground near the slopes. Stable slopes are subjected to long-time rock weathering, river erosion, deformation by tectonic stress, and various types of human activities such as mining, ground water pumping, or irrigation. Those factors gradually undermine the stability of stable slopes. Those slopes have a risk to fail by triggering factors of earthquakes, or/and pore pressure rise during rains or snow melting or by the progress of creeping and its resulting strenth reduction in the potential shear zones.
The first case is the Lishan slope, Xian, China behind the resort palace of Tang Dynasty (A.D. 618-907). The Japan-China joint research on “Assessment of Landslide Hazards in Lishan (Yang-Qe-Fe Palace), Xian, China” (1991-1998) was implemented as one of the IDNDR (International Decade for Natural Disaster Reduction) projects by the government of Japan. The Lishan Palace was constructed at the foot of the fault scar of a big fault. The base rock forming the fault scar was in Precambrian rock mass. The detailed monitoring and a ring shear testing presented the risk of large-scale landslide and its long run out motion. Based on this research, a large scale slope stabilization works were implemented to prevent the landslide forming process in this slope. The success of this project led to IGCP-425 project “Landslide hazard assessment and mitigation for cultural heritage sites and other locations of high societal value” (1998-2003).
The second case is the Inca’s World Heritage Machu Picchu citadel which was constructed at the top of granitic slope. The slope is divided in some blocks; an active landslide block No.1 where the Hiram Bingham Road was constructed on the slope and a precursor stage of landslide (block No.2) where a citadel was constructed. The flat ground of the current citadel site (block No.2) was estimated to be formed by the process that a steep mountain ridge had been removed by a large-scale landslide. Block No.2 is in a process from precursor stage of landslide to an active landslide block similar to Block No.1.
The third case is the 1972 Unzen Mayuyama landslide which destroyed the Shimabara town and killed 15,000 people directly by landslide and the resulting Tsunami wave. The International Consortium on Landslides developed a high stress undrained ring shear apparatus (3 MPa) for the risk assessment of large scale landslide in 2012. It was applied to this 400 m deep landslide and its rapid and long run-out motion. Risk assessment of precursor stage of large scale landslides needs detailed monitoring and geotechnical testing involved materials as well as geological and geomorphologic investigation. This is a frontier study of risk assessment of the precursor stage of large-scale landslides which may destroy important cultural heritages of humankind.

Main causes of natural river damming - Climate change and seismicity: effect on landslide and seismic hazard assessment

Natural rivers damming belongs to the most dangerous natural phenomena in mountainous regions. Both long-living and ephemeral blockages produce devastating primary and secondary effects – submergence of valleys upstream and outburst floods downstream. However, causes and triggers of river's damming, though being studied for more than a century, are still not fully understood. Most often natural dams are associated with glaciation, which is a pure climate-driven process, and with large-scale bedrock landslides, which, in turn, could be triggered either by climatic phenomena such as abnormal precipitation, permafrost degradation, etc., or by endogenic processes, seismicity at the first place. The particular trigger is evident for the historical events, being proved by eyewitnesses and instrumental records. But when we deal with prehistoric features situation became much more complicated. Estimate of both general type of blockages (glacial vs. landslide) and of the latter's triggering factor (seismic vs. aseismic) could be quite controversial. The first controversy can be exemplified by reinterpretation of multiple past blockages in Karakorum mountain range drained by the Indus and its tributaries. Initially they were considered as effects of glaciation until Kenneth Hewitt proved Indus River basin to be a landslide fragmented system. Another, opposite example is the recent reassessment of numerous landslide dams in the adjacent Pamirs region by Nikolay Ischuk who considered them as end moraines (which is wrong from my point of view). Repeated reinterpretation was also made for the gigantic Komansu feature in the Alay Valley that was initially identified by K.V. Kurdiukov as rock avalanche, then reinterpreted by Andrey Nikonov and his coauthors as glacial deposits and reclassified recently by Natalia Resnichenko and Tim Davies back into rock avalanche (from my point of view this gigantic rock slope failure had to contain large proportion of ice). The most controversial and, at the same time critically important problem, is the revealing of real origin of landslide dams. Analysis of publications about origin of large-scale landslides in different mountainous regions show that while in the Alps most of large prehistoric rockslides have been related to the climate change – deglaciation, most of researchers consider very similar features in the Central Asia and Himalayan regions as indication of large prehistoric earthquakes. Prevailing role of the potential energy of rock mass in landslide mobility after slope failure makes any conclusions on their origin based on various geomorphic and depositional criteria quite uncertain. Nevertheless elaboration of reliable and well-grounded method(s) allowing to distinguish seismically triggered and aseismic past landslides is critically important. Understandings of their origin plays a critical role in the long-term assessment of both landslide and seismic hazards and of the effects of the long-term climate change as far as either depend on the processes that develop within the millennia-long time scale.
