The response of glacial masses to climate change is well documented. However, the impact of landslides on glacier dynamics and stability requires greater research. Landslides in glacierized mountains can be caused by climate change (e.g. permafrost thawing), intense precipitation, paraglacial response of slopes or earthquakes and can, in turn, limi...

Since 2010, Google Earth Engine (GEE) has offered a multitude of new options for retrieving and analyzing satellite imagery from various satellite missions. The platform for global geospatial analysis is entirely cloud-based, free of cost, and operated by JavaScript programming. The most notable characteristic of GEE is the fact that satellite imag...

There is a KMZ-file with all 50 Flinn-Engdahl Regions (Flinn and Engdahl, 1965) and their subregions (Young et al., 1996). It is not my data, I just sorted it and it took me a while because I could not find such a sorted KMZ-file online. Maybe someone else finds it useful. > https://www.sciencebase.gov/catalog/item/5a6f547de4b06e28e9caca43 (used S...

Landslides can modify the behavior of glaciers by delivering additional debris load from adjacent slopes onto the ice surface. Such debris covers may significantly reduce ablation and, hence, result in a positive glacier mass balance (e.g., at the Sherman Glacier in Alaska after a series of landslides that had slid onto it during the Good Friday Ea...

To evaluate the functionality of FaultTrace – a tool for semi-automatic structural geological mapping of faults and bedding planes within the software WinGeol by TerraMath –, we demonstrate its detailed use in two different case studies: The Richât Structure in Mauritania is characterized by a volcanogenic anticline with associated fault systems an...

The process of transforming point cloud data into high-quality meshes or CAD objects is, in general, not a trivial task. Many problems, such as holes, enclosed pockets, or small tunnels, can occur during the surface reconstruction process, even if the point cloud is of excellent quality. These issues are often difficult to resolve automatically and...

This is the 2-minutes virtual PICO of the session "GI1.1 - Open session on geoscience instrumentation and methods".

Earthquakes are – amongst many others – one type of triggering factors for mass movements in mountainous regions such as landslides, deep-seated gravitational slides (DSGSD), rockfalls, mudflows, etc. Hence, the emerging hazard would require an area-wide assessment of seismogenic impact to better apprehend the interplay of different triggering fact...

Conference: EGU General Assembly 2021 / At: Vienna, Austria

Being a country exposed to strong seismicity, the estimation of seismic hazard in Tajikistan is essential for urbanized areas, such as the rapidly growing capital city Dushanbe. To ensure people's safety and adequate construction work, a detailed seismic microzonation is the key to proper hazard planning. Existing estimations of seismic hazard date...

WinGeol's FaultTrace is a software tool assisting in semi-automatic structural geological mapping of faults and bedding planes. Digital elevation models – such as, for instance, SRTM or ALOS data – are used in combination with satellite imagery for a first structural geological assessment without the requirement of being at the site. Therefore, it...

The transformation of a point cloud into a CAD object – for example to closed solids or objects closed by NURBS – is not trivial and referred to as “reverse engineering”. We present in this document a workflow of one case study, whose only purpose is to share an efficient procedure. Our workflow is designed for a point cloud recoded by a laser scan...

For many geotechnical purposes, the proper estimation of shapes and dimensions of landslide rupture zones is of significant importance. Very often, this exact delineation is difficult due to the lack of information on rupture zone extents in 3D. Based on a global landslide inventory, this work presents statistical analyses correlating dimension-rel...

The database behind the statistical analyses published in this article is not publicly available. The totality of the results of these analyses – i.e., the various relationships between parameters characterizing landslide volumes – represents one of the deliverables of my doctoral thesis within the Institut Français des Sciences et Technologies de...

Mapping of geological structures (faults, bedding planes, slopes) by using digital elevation data (DEM). FaultTrace supports now composite structures build-up by using several tangential planes and automatically calculates the topology of those input points. In turn, it is possible to interpolate the position and direction of more plane elements. T...

Theoretically, analysis of digital elevation data and remote sensing images allows for convenient mapping of geological settings. Using computer tools, geometric plane elements can be joined with elevation and image data to map structures in 3D. One disadvantage is that single geometric elements are processed consecutively, even if belonging to the...

The majority of numerical landslide models are designed in 2D. In particular, models based on finite difference methods (FDM) are time-consuming and-as a result-in most cases also cost-intensive. 3D models, therefore, increase the processing time significantly. Another contributing factor to long processing times in the context of modeling of seism...

This is the Display (D1437) for the contribution EGU2020-2439. The EGU General Assembly was held online in 2020.

Post-glacial geomorphological settings bearing vast amounts of colluvium as well as alluvial and moraine deposits are typical features in high mountainous environments such as the Himalayas, the Hindu Kush, the Pamir, the Karakoram and the Tien Shan. Due to a lack of alternative living space in narrow valleys, agglomerations are often located on th...

Cet article présente les résultats d'une étude de la géométrie des zones de rupture des glissements de terrain déclenchés par les séismes. Il vient compléter et approfondir les résultats d'un précédent article (DOMEJ et al., 2017) dans lequel les auteurs ont montré que les paramètres liés aux dimensions des glissements de terrain augmentent logique...

Earthquake-triggered slope deformation constitutes a major threat in seismic regions. It is therefore of major interest to properly evaluate expected displacements to ensure appropriate surveillance of concerned slopes. In order to assess and compare deformation patterns along slope surfaces, a series of different seismic scenarios was applied to t...

Seismically induced slope deformation is a worldwide common phenomenon that poses an increasing and considerable threat to fast expanding urbanization, and a great number of catastrophic events throughout the past attest thereof. For this reason, displacement predictions allowing for proper slope surveillance became a major concern.Early attempts t...

The main focus of the database lies on the assessment of geometrical parameters characterizing the rupture masses of the concerned landslides in all their available details. With the objective of data creation for comparative statistical analyses and numerical modeling, a new chronological database of landslides with various kinds of triggers was b...

Landsliding is a worldwide common phenomenon. Every year, and ranging in size from very small to enormous, landslides cause all too often loss of life and disastrous damage to infrastructure, property and the environment. One main reason for more frequent catastrophes is the growth of population on the Earth which entails extending urbanization to...

Ranging in size from very small to tremendous, landslides often cause loss of life and damage to infrastructure, property and the environment. They are triggered by a variety and combinations of causes among which the role of water and seismic shaking have the most serious consequences. In this regard, seismic wave amplification due to topography a...

The understanding of landslide risk due to seismic activity as well as the appropriate response during and after seismic events becomes increasingly important since population increases constantly. Urbanisation extends to seismic regions and to those affected by landslides as secondary effects of earthquakes. In many cases the number of fatalities...

The Pamir region close to the Tajik-Afghan border is regularly affected by severe landslides threatening local population, their livelihood and infrastructure. In addition to landslides appearing as immediate consequence of earthquake, a high number of ground movements without previous seismic activity are also observed. The number of reported even...

Typically for the High Pamir huge amounts of postglacial and fluviatile debris as well as moraine deposits cover the valley bottom of the Sharfdara. At many locations this condition does not provide a stable basement and thus the contemporary area of Tusion experienced severe landslides as a result of glacial recession after the last ice age. Slope...

Man nimmt an, dass weltweit die Häufigkeit von Erdbeben bezüglich ihrer Magnituden einem bestimmten Gesetz folgt. In dieser Arbeit wird der Frage nachgegangen, ob das so genannte Gutenberg-Richter-Gesetz auch für Erdbeben mit großen Magnituden gilt. Allgemein steht die Vermutung, dass das Gesetz nicht unbegrenzt, sondern nur bis zu einer bestimmten...
