COSEISMIC DEFORMATION FIELD AND FAULT SLIP DISTRIBUTION OF THE 2015 CHILE Mw8.3 EARTHQUAKE [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
On September 16, 2015, a magnitude 8.3 earthquake struck west of Illapel, Chile. We analyzed Sentinel-1A/IW InSAR data on the descending track acquired before and after the Chile Mw8.3 earthquake of 16 September 2015.

Cajon Pass and the Southern San Andreas Fault System: Earthquake Cycle Stress Accumulation and Present‐Day Loading

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract With over a century since the last major rupture affecting the wider Los Angeles region, tectonic stress has steadily built along the southern San Andreas and San Jacinto fault systems, raising concerns of an imminent large earthquake. Cajon Pass, located at the junction of these faults, represents a critical site for potential through‐going ...

Hydrological Impact of Earthquakes on Reverse and Normal Faults: Results From Numerical Models

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract I investigate earthquake‐induced hydrological signals related to poroelastic deformation, thermal pressurization, fault‐zone dilatancy and rupture of a pressurized reservoir at depth. This is performed using a two dimensional plane strain model that simulates ruptures on reverse and normal faults governed by rate‐and‐state friction coupled to ...

Precise Temperature Measurements and Long‐Term Observations Revealed an Almost‐Constant Temperature Zone in a Vertical 700‐m‐Deep Borehole in the Aso Volcanic Region

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract To determine the subsurface temperature distribution and its relevance to groundwater flow in the deep subsurface, we repeated temperature depth profile measurements and conducted long‐term temperature observations in an ∼700‐m‐deep borehole penetrating the Futagawa fault along the Kiyama–Kashima graben in the Aso volcanic region, Japan from ...

Postseismic deformation in Chile: Constraints on the asthenospheric viscosity

Geophysical Research Letters, 1999
By means of a spherical Earth model with Maxwell rheology, an analysis of the postseismic deformation field due to the viscoelastic relaxation of the mantle and asthenosphere following the great 1960 Chile earthquake is performed. Due to the exceptional energy release of that earthquake, geomorphological evidences of postseismic deformation are ...

Subducting Slab Thermo‐Petrologic Structure and Intermediate‐Depth Supra‐Slab Earthquakes Beneath Southern Colombia

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We develop 2‐D thermo‐petrologic models for two transects through southern Colombia and compare the model‐predicted temperature distributions and depths of slab dehydration with seismological observations. Along the northern transect, earthquakes occur above the relatively young subducting Nazca slab at 80–160‐km depths.

Afterslip From the 2020 M 6.5 Monte Cristo Range, Nevada Earthquake

Geophysical Research Letters, 2022
We investigate postseismic deformation following the 15 May 2020, Mw 6.5 Monte Cristo Range, Nevada earthquake using geodetic and aftershock data. Seven months of Sentinel 1‐A/B SAR images were used to model deformation as afterslip on two subparallel ...

Coseismic and postseismic deformation associated with the 2003 Chengkung, Taiwan, earthquake [PDF]

Geophysical Journal International, 2009
SUMMARY We use GPS-derived coseismic and postseismic displacements of the 2003 Mw 6.8 Chengkung, Taiwan, earthquake to examine seismogenic behaviour of the southern Longitudinal Valley. We invert for fault slip on the Chihshang fault, a segment of the Longitudinal Valley fault, based on a simplified layered earth model and a listric-shape fault ...

Does Geocentric Sea‐Level Rise in the Maritime Continent Reveal a Tectonic Fingerprint?

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The islands of the Maritime Continent are highly vulnerable to sea‐level rise driven by barystatic, sterodynamic, and vertical land motion (VLM) processes. While tectonics is known to affect relative sea‐level through VLM, its influence on long‐term geocentric sea level (GSL) through crustal deformation and gravity field perturbations remains ...

Interseismic, Coseismic, and Early Postseismic Slip Associated With the 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic afterslip associated with the 2025 Mw 8.8 Kamchatka earthquake.
