An integrated SEM-Newmark model for physics-based regional coseismic landslide assessment
Soil Dynamics and Earthquake Engineering, 2020 Earthquake-induced landslides are one of the most catastrophic effects of earthquakes, as evidenced by many historic events over the past decades, such as the 1994 Northridge earthquake in California and the 2008 Wenchuan earthquake in China.

A numerical simulation of seismic signals of coseismic landslides
Engineering Geology, 2021Abstract When a coseismic landslide is triggered by an earthquake, seismic stations close to the location of the landslide will simultaneously record the seismic signals caused by the earthquake and landslide, causing confusion between the two signals.

Hybrid Computational Intelligence Modeling of Coseismic Landslides’ Severity
2021Coseismic Landslides (COLA) are one of the most widespread and destructive hazards to result from earthquakes in mountainous environments. They are always associated with almost instantaneous slope collapse and spreading, posing significant hazards to human lives and lifeline facilities worldwide.

The 2018 Palu Tsunami: Coeval Landslide and Coseismic Sources
Seismological Research Letters, 2020AbstractOn 28 September 2018, Indonesia was struck by an MW 7.5 strike-slip earthquake. An unexpected tsunami followed, inundating nearby coastlines leading to extensive damage. Given the traditionally non-tsunamigenic mechanism, it is important to ascertain if the source of the tsunami is indeed from coseismic deformation, or something else, such as ...

Secondary Hazards Associated with Coseismic Landslide
2012Landslide hazards induced by earthquakes are classified into a primary hazard and a secondary hazard from temporal and spatial viewpoints of damages. Working Group 3 (WG-3) of the Earthquake-induced Landslides Research Projects comprehensively investigated the secondary hazards associated with coseismic landslide. First of all, we provided a definition

Classification of Coseismic Landslides Using Fuzzy and Machine Learning Techniques
2020Seismically generated landslides represent one of the most damaging hazards associated with earthquakes in countries with high seismicity. The delineation of prone to coseismic landsliding areas is crucial in order to predict the occurrence of earthquake-induced landslides and consequently reduce the relevant risk.

Development of the coseismic landslide susceptibility map of the island of Lefkada, Greece
Environmental Earth Sciences, 2021The island of Lefkada, Greece periodically suffered environmental and structural damages induced by earthquakes. During the twenty-first century, two moderate events of magnitude M > 6 occurred in 2003 and 2015 (M6.2 and M6.5, respectively). The dominant type of the earthquake-induced environmental failures was rock falls and slides that were ...

Regression models for estimating coseismic landslide displacement
Engineering Geology, 2007Newmark's sliding-block model is widely used to estimate coseismic slope performance. Early efforts to develop simple regression models to estimate Newmark displacement were based on analysis of the small number of strong-motion records then available. The current availability of a much larger set of strong-motion records dictates that these regression

Limits to coseismic landslides triggered by Cascadia Subduction Zone earthquakes
Geomorphology, 2022Landslides are a significant hazard and dominant feature throughout the landscape of the Pacific Northwest. However, the hazard and risk posed by coseismic landslides triggered by great Cascadia Subduction Zone (CSZ) earthquakes is highly uncertain due to a lack of local and global data.

Lichen dating of coseismic landslide hazards in alpine mountains
Geomorphology, 1994Abstract Studies of rockfalls and block slides provide insight about seismic shaking hazards in alpine mountains subject to earthquakes. Large samples of the longest axis of the largest lichen on each block can be used to identify regional landslide events; lichen-size distributions for many sites cluster consistenly at the same sizes.
