Co-Seismic Inversion and Post-Seismic Deformation Mechanism Analysis of 2019 California Earthquake [PDF]

Remote Sensing, 2021
In July 2019, a series of seismic events, including a magnitude (Mw) 7.1 mainshock and Mw 6.4 foreshock, occurred in Eastern California. Studying these seismic events can significantly improve our understanding of the Eastern California tectonic ...

Study on co-seismic deformation wave characteristics of crustal deformation observation records in Ankang area

地震科学进展, 2022
Based on the observation records of deformation stations in Ankang area from 2017 to 2020, we compared and analyzed the earthquake-reflecting capacity of six sets of instruments, and systematically discussed the relationship between the source parameters

Retrieving Three-Dimensional Co-Seismic Deformation of the 2017 Mw7.3 Iraq Earthquake by Multi-Sensor SAR Images

Remote Sensing, 2018
The Mw7.3 Iraq earthquake on 12 November 2017 was the largest recorded earthquake in the Zagros Mountains since 1900. In order to quantitatively analyze the co-seismic deformation caused by this earthquake, both the ascending and descending SAR images ...

Deep learning model for co-seismic response detection of fixed-point deformation data

地震科学进展
Co-seismic response identification of fixed-point deformation data currently relies on manual selection, and no automatic co-seismic response detection method has yet been applied.

Seismic anisotropy in siliciclastic reservoir rocks [PDF]

, 2006
The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements

InSAR Constrained Downdip and Updip Afterslip Following the 2015 Nepal Earthquake: New Insights into Moment Budget of the Main Himalayan Thrust

Remote Sensing, 2022
We use ALOS-2 and Sentinel-1 data spanning 2015–2020 to obtain the post-seismic deformation of the 2015 Mw 7.8 Nepal earthquake. ALOS-2 observations reveal that the post-seismic deformation was mainly distributed in four areas.
