Coseismic Rupture Behaviors of the January and March 2022 M_W > 5.5 Hala Lake Earthquakes, NE Tibet, Constrained by InSAR Observations

Remote Sensing, 2023
On 23 January and 25 March 2022, two MW > 5.5 Hala Lake earthquakes characterized by right-lateral strike-slip faulting occurred around the Elashan Fault in Northeastern Tibet, marking the two largest events since the 1927 MW 6.2 Hala Lake earthquake ...

Identification of Paleoearthquakes and Coseismic Slips on a Normal Fault Using High-Precision Quantitative Morphology: Application to the Jiaocheng Fault in the Shanxi Rift, China

Lithosphere, 2021
The quantitative morphology of bedrock fault surfaces combined with aerial surveys and field identification is a useful approach to identify paleoearthquakes, obtain coseismic slips, and evaluate the seismogenic capacity of active faults in bedrock areas

Linking Stress Drop and Slip Heterogeneity to Assess Source Rupture Directivity for Earthquakes in Central Italy

Terra Nova, EarlyView.
ABSTRACT In this study, we examine the relationship between Brune stress drop and fault slip where the stress drop is estimated using the Empirical Green's Function (EGF) method and slip distribution is derived from seismic and geodetic data inversion.

Evolution of Pore Fluid Pressure in an Accretionary Outer Wedge Over Megathrust Earthquake Cycles: The Northern Cascadia Example

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The evolution of pore fluid pressure ( Pf$P_{\mathrm{f}}$) in the most seaward portion of a subduction accretionary prism plays an essential role in the cycle of tsunamigenic earthquakes. Based on recent geophysical observations, here we propose a testable conceptual model for this evolution for northern Cascadia offshore of Washington.

Superficial simplicity of the 2010 El Mayor–Cucapah earthquake of Baja California in Mexico [PDF]

, 2010
The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures.

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.

Effects of Fault Roughness on Coseismic Slip and Earthquake Locations

Journal of Geophysical Research: Solid Earth, 2019
AbstractFault zone structure is well known to exert strong controls on earthquake properties including coseismic slip distribution, rupture propagation direction, and hypocenter location. It has also been well established that the principal slip surface, which accommodates the majority of earthquake displacement, exhibits roughness at all scales ...

Multi‐Stage Shallow Rupture and Pre‐Event Shallow Deformation During the 2025 Mw 5.9 Asadabad Earthquake (Afghanistan)

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The 31 August 2025 Mw 5.9 Asadabad earthquake in eastern Afghanistan caused severe damage despite its moderate magnitude, raising questions about rupture processes and seismic hazard in the southern Hindu Kush. Using Sentinel‐1 InSAR and teleseismic waveform modeling, we reveal a complex, multi‐stage shallow (4–5 km) rupture involving the ...

Mode of Strain Release Associated with Major Earthquakes in Japan [PDF]

, 1973
It is now widely accepted that most shallow earthquakes are caused by a sudden release of tectonic stress, and therefore strain, in the form of faulting (56, Chap. 14).
