The coseismic deformation field on both sides of the fault, especially the distribution and change characteristics of near-field deformation, not only provides important constraints for the fine inversion of the slip distribution model but also serves as

On January 19, 2020, an M w 6.0 earthquake occurred in Jiashi, Xinjiang Uygur Autonomous Region of China. The epicenter was located at the basin-mountain boundary between the southern Tian Shan and the Tarim Basin.

Abstract While large earthquakes can alter groundwater systems far from the epicenter, their hydromechanical changes remain elusive. We investigate the 2011 Mw 9.0 Tohoku earthquake's impact on a deep well‐aquifer system ∼2,000 km from the epicenter. By employing the groundwater tidal and barometric pressure response methods, we perform tidal response ...

Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Abstract We investigate the spatiotemporal evolution of foreshocks preceding the 2025 Mw 8.8 Kamchatka earthquake by applying single‐station analysis to waveforms recorded at the nearest seismic station. Our results reveal a southwestward migration of foreshocks toward the mainshock epicenter through multiple stages, with a migration speed of ∼7.0 km ...

Abstract The Yingxiu–Beichuan Fault Zone (YBFZ), located in the Longmen Shan Thrust Belt (LSTB) on the eastern Tibetan Plateau, is highly seismically active. However, direct evidence of large earthquakes at depth is scarce. Here, we present rock magnetic, microstructural, and geochemical analyses of four fault zones from the Wenchuan Earthquake Fault ...

Depth-varying rupture properties of subduction zone megathrust faults [PDF]
Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (M_w 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (M_w 9.0) great earthquakes had similar depth variations

A hybrid spectral and finite element method for coseismic and postseismic deformation
Abstract We investigate the elastic and viscoelastic responses of the Earth to a sudden slip along a fault. Firstly, equations describing the Earth’s infinitesimal deformations for elastic and viscoelastic rheological models are introduced within the weak formulation and the theorems of existence and uniqueness of solutions are demonstrated.

Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...
