The stress change of the major activity faults in the Weihe Graben after the Wenchuan earthquake

Available online 20 August 2021
Sheng Dong | Weina Yuan | Fuqiang Shi

The seismicity of small earthquakes in the Weihe Graben has changed after the Wenchuan earthquake. In detail, the seismicity around the Qishan-Mazhao fault in the western Weihe Graben decreased, while...

A Multi-Channel Approach for Automatic Microseismic Event Association using RANSAC-based Arrival Time Event Clustering (RATEC)

Available online 13 August 2021
Lijun Zhu | Lindsay Chuang | James H. McClellan | Entao Liu | Zhigang Peng

In the presence of background noise, arrival times picked from a surface microseismic data set usually include a number of false picks that can lead to uncertainty in location estimation. To eliminate...

Viscoelastic relaxation of the upper mantle and afterslip following the 2014 MW8.1 Iquique earthquake

January 2021
Zhiping Hu | Yan Hu | Segun Steven Bodunde

An improved understanding of postseismic crustal deformation following large subduction earthquakes may help to better understand the rheological properties of upper mantle and the slip behavior of...

Research progress on layered seismic anisotropy - A review

January 2021
Shengyi Shen | Yuan Gao

Seismic anisotropy is an effective feature to study the inner structure of the Earth. In complex tectonic area, the assumption of single-layer anisotropy is sometimes not well consistent with the observed...
