Investigating an Earthquake Surface Rupture Along the Kumysh Fault (Eastern Tianshan, Central Asia) from High-Resolution Topographic Data

Remote Sensing
As direct geomorphic evidence and records of earthquakes on the surface, coseismic surface ruptures have long been a key focus in earthquake research. However, compared with strike-slip and normal faults, studies on reverse-fault surface ruptures remain ...

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

GPS Solutions
AbstractUnmodeled 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. While non-tectonic ‘jumps’, such as equipment changes, affect only a specific GNSS station, seismically-induced displacements can ...

Coseismic Vertical Displacement for a Shallow Thrust Earthquake From EarthDEM Data

Geophysical Research Letters
Abstract Coseismic vertical displacements are important observations that help improve our understanding of fault mechanisms and how earthquakes alter landscapes. It has been a challenge to quantify long‐wavelength topographic changes for thrust earthquakes using optical satellite imagery, as most recent studies focus on strike‐slip ...
