In-situ soft sediment deformation structures (SSDS) are commonly used as paleoseismic indicators in marine and lacustrine sedimentary records. Earthquake-related shear can deform the shallow subsurface through Kelvin-Helmholtz instability. The SSDS related to instability have been quantify shaking strength of past earthquakes. However, relative importance i) lithology physical properties, ii) p...

This document provides an assessment of the current state of advanced airborne and spaceborne remote sensing and ground-based technologies applicable to the analysis of seismic risk and vulnerability of buildings and lifeline systems. Continuous Global Positioning System (GPS) ground deformation monitoring and seismological networks provide critical measurements for understanding the earthquake...

Anthropogenic fluid injections at depth induce seismicity which is generally organized as swarms, clustered in time and space, with moderate magnitudes. Earthquake swarms also occur various geological contexts such subduction zones, mountain ranges, volcanic, geothermal areas. While some similarities between anthropogenic natural have already been observed, whether they are driven by the same m...

Widespread seismicity was triggered by the June 28, 1992, Landers California, earthquake at a rate which was maximum immediately after passage of the exciting seismic waves. Rectified diffusion of vapor from hydrothermal liquids and magma into bubbles oscillating in an earthquake can increase the local pore pressure to seismically significant levels within the duration of the earthquake. In a h...

Abstract Earthquake disasters are frequent, and the seismic intensity is large in Northeast China. activity research an important aspect of earthquake disaster management. We chose some unconventional means to study fault activity, find updated evidence. The Ms 5.3 occurred near Fuyu North Fault (FNF) China on May 27, 2018. Using Sentinel-1B descending orbit data from 2016 2019, line-of-sight (...

Interferometric synthetic aperture radar (InSAR) data over the area of the Hector Mine earthquake (Mw7.1, 16 October 1999) reveal postseismic deformation of several centimeters over a spatial scale of 0.5 to 50 km. We analyzed seven SAR acquisitions to form interferograms over four time periods after the event. The main deformation seen in the line-of-sight (LOS) displacement maps are a region ...

We developed a kinematic earthquake cycle model applicable to transform fault zones, subduction zones, and collision zones on the basis of elastic dislocation theory. The crustal deformation associated with the periodic occurrence of interplate earthquakes is generally given by the superposition of viscoelastic responses to steady slip on the whole plate boundary, steady back slip on the seismi...

High-quality seismic data recorded during the 1999 Taiwan Chi-Chi earthquake (Mw=7.6) show that a smallscale orogenic process of both mountain-building and crust-thickening was simultaneously accomplished along one set of crustal-scale conjugated faults. Mountain-building near the surface was primarily produced by the main shock along an eastward low-angle thrust fault in the upper crust. In th...
