Source Model and Triggered Aseismic Faulting of the 2021 Mw 7.3 Maduo Earthquake Revealed by the UAV-Lidar/Photogrammetry, InSAR, and Field Investigation

Remote Sensing, 2022
Multi-source datasets, including the UAV-Lidar/Photogrammetry, InSAR, and field investigation data, have been used for revealing the complex surface displacement pattern and focal mechanism of the 2021 Maduo Mw 7.3 earthquake. First, a co-seismic surface

Is Coulomb stress the best choice for aftershock forecasting?

, 2020
The Coulomb failure stress (CFS) criterion is the most commonly used method for predicting spatial distributions of aftershocks following large earthquakes. However, large uncertainties are always associated with the calculation of Coulomb stress change.

The spatial response pattern of coseismic landslides induced by the 2008 Wenchuan earthquake to the surface deformation and Coulomb stress change revealed from InSAR observations

International Journal of Applied Earth Observations and Geoinformation, 2020
The 2008 Mw 7.9 Wenchuan earthquake triggered plenty of coseismic giant landslides, which resulted in almost one third of total fatalities and economic losses during the event.

Importance of forearc topography for the triggering of aftershocks of megathrust earthquakes: insights from mechanical models and the Tohoku-Oki and Maule earthquakes [PDF]

Solid Earth
Aftershocks of megathrust earthquakes at subduction zones may be driven by stresses arising from the topography of the forearc. However, the effect of topographic stresses on aftershock triggering is quantitatively not well understood and has been ...

Analysis of the stress distribution of North Anatolian Fault Zone for the part between Amasya-Tokat cities

Bulletin of the Mineral Research and Exploration, 2022
Tectonic forces formed in the continental crust, cause permanent changes in stress, compression and deformation. The amplitudes of earthquake waves vary with the stress/strain distribution in the crust.

Aftershocks in Stress Shadows are Inconsistent with Modeled Static Coulomb Stress Changes

Seismica
Aftershock triggering is commonly attributed to increases in static Coulomb stress.  In some areas, termed "stress shadows", a decrease in Coulomb stress is predicted to suppress earthquake occurrence.
