Data recorded by a seismic network deployed the day after the 2004 Mid Niigata Prefecture Earthquake (M6.8) in central Japan are used to determine the major source faults responsible for the mainshock and major aftershocks. Using this high-resolution seismic data, three major source faults are identified: two parallel faults dipping steeply to the west located 5 km apart, and the other dipping eas...... hiện toàn bộ
Investigating slow-moving shallow soil landslides using Sentinel-1 InSAR data in Gisborne, New ZealandLandslides - Tập 20 - Trang 427-446 - 2022

Landslides are widespread geomorphological features on the North Island of New Zealand, where they represent one of the primary landscape-forming processes. This study focuses on the steepland terrain surrounding Gisborne, a city located on the east coast of the North Island, at the Hikurangi subduction margin. This terrain consists of young, weak, sedimentary rocks and soils; the most common mode...... hiện toàn bộ
Experimental investigation on the impact force of the dry granular flow against a flexible barrierLandslides - Tập 17 - Trang 1465-1483 - 2020
Xiao Siyou, Su Lijun, Jiang Yuanjun, Qu Xin, Xu Min, Hu Xiaobo, Liu Zhenyu
To reveal the composition and distribution of the impact force of the dry granular flow against a flexible barrier, five groups of physical experiments in different slope angles have been carried out. The flow velocities, flow heights and tensile forces of the cables were measured using the high camera and the load cells. Then we developed a model to calculate the total impact force of the dry gra...... hiện toàn bộ
Three Dimensional Landslide Generated Tsunamis: Numerical and Physical Model ComparisonsLandslides - Tập 17 - Trang 1145-1161 - 2019

Tsunamis are one of the most catastrophic natural hazards that can devastate coastal regions. Most common mechanisms that generate tsunamis are undersea earthquakes and submarine landslides. However, in enclosed basins, such as fjords, reservoirs, and lakes, subaerial landslides can also generate devastating tsunamis with similar or worse consequences, because of a more efficient wave generation. ...... hiện toàn bộ
Does parameterization influence the performance of slope stability model results? A case study in Rio de Janeiro, BrazilLandslides - Tập 14 - Trang 1389-1401 - 2016
Carolina de Lima Neves Seefelder, Sérgio Koide, Martin Mergili
We produce factor of safety (FOS) and slope failure susceptibility index (SFSI) maps for a 4.4-km2 study area in Rio de Janeiro, Brazil, in order to explore the sensitivity of the geotechnical and geohydraulic parameterization on the model outcomes. Thereby, we consider parameter spaces instead of combinations of discrete values. SFSI is defined as the fraction of tested parameter combinations wit...... hiện toàn bộ
A new slope mass rating in mountainous terrain, Jammu and Kashmir Himalayas: application of geophysical technique in slope stability studiesLandslides - Tập 10 - Trang 255-265 - 2012

The slopes of western Lesser Himalaya (at Sangaldhan Block of Udhampur near Ramban, Jammu and Kashmir India) are being severely affected by tectonic and erosional activities. These activities result in deposit of a thick cover of rock fragments and overburden just above the hard rock. The thickness of overburden cover has directly affected the stability of slope in the study area, though the tradi...... hiện toàn bộ
