Coseismic Rupture and Postseismic Afterslip of the 2020 Nima Mw 6.4 Earthquake

Remote Sensing
On 22 July 2020, an Mw 6.4 earthquake occurred in Nima County in the Qiangtang Terrane of the central Tibetan Plateau. This event, caused by normal faulting, remains controversial in terms of its rupture process and causative fault due to the complex ...

Characteristics of normal-fault earthquake deformation in the Qinghai-Tibet Plateau revealed by InSAR

地球与行星物理论评, 2023
The north-south convergence and east-west extension of the Tibet Plateau are accommodated by a series of active strike-slip and normal faults, and normal-fault earthquakes are very active in the plateau. During 2020 to 2021, there were three normal-fault

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

Coseismic seafloor deformation in the trench region during the Mw8.8 Maule megathrust earthquake [PDF]

Scientific Reports, 2017
AbstractThe Mw 8.8 megathrust earthquake that occurred on 27 February 2010 offshore the Maule region of central Chile triggered a destructive tsunami. Whether the earthquake rupture extended to the shallow part of the plate boundary near the trench remains controversial. The up-dip limit of rupture during large subduction zone earthquakes has important

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 ...

Coseismic and postseismic deformation of the 2011 Tohoku‐Oki earthquake constrained by GRACE gravimetry [PDF]

Geophysical Research Letters, 2012
Spaceborne gravimetry data from the Gravity Recovery And Climate Experiment (GRACE) are processed using spatio‐spectral Slepian localization analysis enabling the high‐resolution detection of permanent gravity change associated with both coseismic and postseismic deformation resulting from the great 11 March 2011 Mw 9.0 Tohoku‐Oki earthquake. The GRACE

Coseismic and postseismic deformation associated with the 2016 Mw 7.8 Kaikoura earthquake, New Zealand: fault movement investigation and seismic hazard analysis

Earth, Planets and Space, 2018
The 2016 moment magnitude (Mw) 7.8 Kaikoura earthquake demonstrated that multiple fault segments can undergo rupture during a single seismic event. Here, we employ Global Positioning System (GPS) observations and geodetic modeling methods to create ...

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 ...

Multi‐Scale Rate‐ and Roughness‐Dependent Frictional Constitutive Law and Dynamic Earthquake Sequence Simulation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract The physical mechanisms that govern the multi‐scale source properties of earthquakes, such as fracture energy scaling, where the dynamic energy dissipation of earthquakes scales with fault slip, remain debatable. We introduced the rate‐ and roughness‐dependent friction (RRF) law which accounts for the multi‐scale roughness evolution of the ...
