Detecting Coseismic Landslides in GEE Using Machine Learning Algorithms on Combined Optical and Radar Imagery [PDF]

Remote Sensing
Landslides, resulting from disturbances in slope equilibrium, pose a significant threat to landscapes, infrastructure, and human life. Triggered by factors such as intense precipitation, seismic activities, or volcanic eruptions, these events can cause ...

Response of coseismic landslide susceptibility to the temporal scales and interactions of deformation and rainfall

Geomatics, Natural Hazards & Risk
This study examines how the time scales of rainfall and deformation and their interaction affect coseismic landslide susceptibility assessment. Based on 5007 landslides triggered by the 5 September 2022, Luding earthquake, we integrated 18 causative ...

Hazard assessment modeling and software development of earthquake-triggered landslides in the Sichuan–Yunnan area, China [PDF]

Geoscientific Model Development, 2023
To enhance the timeliness and accuracy of spatial prediction of coseismic landslides, we propose an improved three-stage spatial prediction strategy and develop corresponding hazard assessment software named Mat.LShazard V1.0.

On the Dynamic Fragmentation and Lubrication of Coseismic Landslides [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractThe three‐dimensional discrete element method has been employed to analyze the dynamic fragmentation and lubrication mechanisms of coseismic Tangjiashan landslide induced by the 2008 Ms 8.0 Wenchuan earthquake. The numerical results show that the internal rock damage occurs and propagates gradually along the basal failure plane due to seismic ...

Seismic and geomorphic assessment for coseismic landslides zonation in tropical volcanic contexts [PDF]

Natural Hazards, 2022
AbstractThe Poás volcano is an active volcano of Costa Rica with intense tectonic activity in its flanks. Historically, the volcano has presented strong, surficial earthquakes provoking many landslides with associated casualties and immense economic impacts. One example is the Cinchona earthquake in 2009 (Mw 6.2 and 4.6 km depth). We aim to determine a

Two public inventories of landslides induced by the 10 June 2022 Maerkang Earthquake swarm, China and ancient landslides in the affected area

Natural Hazards Research, 2022
The June 10, 2022 Ms5.8, Ms6.0 and Ms5.2 earthquake swarm of Maerkang, Sichuan, China has triggered a lot of landslides. The primary purpose of this paper is to prepare a detailed coseismic landslides inventory and ancient landslide inventory in the ...
