Recent Advances in Stability and Failure Mechanisms of Landslide Dams

Frontiers in Earth Science, 2021
Numerous landslide dams have been induced in recent years as a result of frequent earthquakes and extreme climate hazards. Landslide dams present serious threats to lives and properties downstream due to potentially breaching floods from the impounded ...

The Generation of the Target Aftershock Spectrum Based on the Conditional Mean Spectrum of Aftershocks

Buildings, 2023
Numerous studies have examined the responses of various structures to the mainshock–aftershock (MS–AS) ground motion, and the MS–AS ground motions are very important as the input.

Dynamic Earthquake Triggering in Southern California in High Resolution: Intensity, Time Decay, and Regional Variability

AGU Advances, 2021
Earthquake triggering by seismic waves has been recognized as a phenomenon for nearly 30 years. However, our ability to study dynamic triggering has been limited by our ability to capture the triggering stresses accurately and record the resultant ...

Analysis of Aftershock Parameters for the Alaskan Subduction Zone Tectonic Region [PDF]

, 2022
On 29 July 2021, a magnitude 8.2 earthquake was felt by over 200 people near Perryville, Alaska. The early aftershock forecasts issued by the USGS use default parameters based on expected productivity within a given tectonic region.

Evaluation of aftershock hazard of the 2018 M 6.2 Hualien earthquake

Terrestrial, Atmospheric and Oceanic Sciences, 2019
This paper presents a near real-time evaluation of earthquake hazard after the shallow ML 6.2 Hualien shock of depth 10.6 km occurred 2350 LT, 6 February 2018 at epicenter (24.10°N, 121.73°E). Since a large aftershock intends to bring up a new aftershock

Precursory Tidal Triggering of the 2011 Mw 9.0 Tohoku Aftershocks

Applied Sciences, 2022
Precursory earth tidal triggering is believed to influence earthquake timing preferentially when a region is critically stressed. However, whether and how the recurrence of aftershocks after a giant earthquake is affected by tidal triggering remains ...

Fragility Analysis of Masonry Structures Subjected to Random Sequential Ground Motions

Buildings
In this study, a fragility analysis of masonry structures is conducted using a random sequential ground motion model. Initially, the relationship between a mainshock and its aftershocks is clarified based on the physical mechanism of “source-path-local ...
