Coseismic fault-slip distribution of the 2019 Ridgecrest Mw6.4 and Mw7.1 earthquakes [PDF]
Scientific Reports, 2021 AbstractThe 2019 Ridgecrest, California seismic sequence, including an Mw6.4 foreshock and Mw7.1 mainshock, represent the largest regional seismic events within the past 20 years. To obtain accurate coseismic fault-slip distribution, we used precise positioning data of small earthquakes from January 2019 to October 2020 to determine the dip parameters ...

Pre‐Existing Off‐Fault Damage Can Impede Coseismic On‐Fault Slip
Geophysical Research LettersPrimarily due to the scarce direct field evidence along a same fault, understanding the relationship between the pre‐existing off‐fault damage and coseismic slip distribution remains challenging.

Thermochemical pressurization of faults during coseismic slip [PDF]
Journal of Geophysical Research: Solid Earth, 2010 During earthquakes, frictional heating on the fault plane induces a temperature rise and thus a pore pressure rise, which is known as thermal pressurization (TP). Coseismic mineral dehydrations may occur because of this temperature increase and are included within the TP framework.

Sensitivity Analysis for Seafloor Geodetic Constraints on Coseismic Slip and Interseismic Slip-Deficit Distributions [PDF]
Frontiers in Earth Science, 2021 Estimating the coseismic slip distribution and interseismic slip-deficit distribution play an important role in understanding the mechanism of massive earthquakes and predicting the resulting damage. It is useful to observe the crustal deformation not only in the land area, but also directly above the seismogenic zone.

Coseismic slip distribution of the 1946 Nankai earthquake and aseismic slips caused by the earthquake [PDF]
Earth, Planets and Space, 2014 Coseismic slip distribution on the fault plane of the 1946 Nankai earthquake (Mw 8.3) was estimated from inversion of tsunami waveforms. The following three improvements from the previous study (Satake, 1993) were made. (1) Larger number of smaller subfaults is used; (2) the subfaults fit better to the slab geometry; and (3) more detailed bathymetry ...

Coseismic slip inversion based on InSAR arc measurements [PDF]
Natural Hazards and Earth System Sciences, 2013 Abstract. We present a new method for inverting coseismic slip distribution based on arc measurements of InSAR interferograms. The method only solves the integer ambiguities on the selected arcs so that the challenging task from global unwrapping of low coherence interferograms can be avoided.

Slow Fault Slip Signatures in Coseismic Ionospheric Disturbances
Geophysical Research Letters, 2022 Abstract Rise times of earthquake moment release influence the spectra of seismic waves. For example, slow fault movements in tsunami earthquakes excite larger tsunamis than expected from intensities of short‐period seismic waves.

Slow slip events following the afterslip of the 2002 Mw 7.1 Hualien offshore earthquake, Taiwan
Earth, Planets and Space, 2022 Geodetic evidence for slow slip recurrence changed by stress perturbations was rare, especially from afterslip following a nearby large earthquake. The first observed slow slip events in the southernmost Ryukyu subduction had occurred in 2005, 2009, and ...

Imaging coseismic rupture in far field by slip patches [PDF]
Geophysical Journal International, 2004 SUMMARY Since the end of the 1970s, teleseismic waves are used routinely to infer the first-order characteristics of the event (location, depth, duration, focal mechanism), but finding the second-order kinematic parameters (spatial distribution of slip, rupture velocity and more basically the discrimination between the fault plane and the other nodal ...
