Coseismic Coulomb stress changes induced by a 2020–2021 MW > 7.0 Alaska earthquake sequence in and around the Shumagin gap and its influence on the Alaska-Aleutian subduction interface

Geodesy and Geodynamics
Three MW > 7.0 earthquakes in 2020–2021 occurred in the Shumagin seismic gap and its adjacent area of the Alaska-Aleutian subduction zone, including the MW7.8 Simeonof thrust earthquake on July 22, 2020, the MW7.6 Sand Point strike-slip earthquake on ...

Re-examination of TEC anomalies in the ionosphere before large earthquakes

Earth, Planets and Space
We examine GNSS-derived total electron content (TEC) variations preceding four large megathrust earthquakes: the 2011 Tohoku–Oki (Mw 9.0), 2014 Iquique (Mw 8.2), 2015 Illapel (Mw 8.3), and 2009 Dusky Sound (Mw 7.8) events.

A New Analytical Simulation Code of Acoustic-Gravity Waves of Seismic Origin and Rapid Co-Seismic Thermospheric Disturbance Energetics

Atmosphere
A recent study the detection of coseismic ionospheric disturbances or ionoquakes less than 400 s from the earthquake’s onset. The study also associates these rapid ionoquakes with the seismo-atmosphere–ionosphere (SAI) coupling mechanism energized by ...

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 ...

The 2012 Emilia earthquake in northern Italy: coseismic geological effects within a compressive tectonic framework. [PDF]

, 2012
On May 20 2012 a Ml 5.9 seismic event hit the Emilia Po Plain area (northern Italy) triggering an intense earthquake activity along a broad area of the Plain.

An empirical tool for predicting the presence or absence of coseismic displacements at GNSS stations [PDF]

Unmodeled displacements in GNSS times series, induced by instrumental artifacts or geophysical events, create significant biases in station trajectory parameters that can propagate into the reference frame itself.

Crustal deformation in extensional regimes: Iceland, Nevada and SW Turkey [PDF]

, 1996
In 1991 a 23-point, 30 x 25 km, GPS geodetic network was established in the Hengill ridge-ridge-transform triple junction, SW Iceland. The GPS data were processed using the Bernese V3.2 software.
