Relation between stress heterogeneity and aftershock rate in the rate-and-state model [PDF]

, 2006
We estimate the rate of aftershocks triggered by a heterogeneous stress change, using the rate-and-state model of Dieterich [1994].We show that an exponential stress distribution Pt(au) ~exp(-tautau_0) gives an Omori law decay of aftershocks with time ~1/

Sustained supershear rupture during the 2025 Mandalay, Myanmar earthquake

Communications Earth & Environment
The 2025 Mw 7.8 Myanmar earthquake ruptured the Sagaing fault, where sparse near-fault seismic observations limit source characterization. Here, we integrate optical imagery, InSAR, finite-fault slip inversion, back-projection (BP), and dynamic rupture ...

Crustal deformation in Hong Kong: Insights from GNSS observations and geophysical models

International Journal of Applied Earth Observations and Geoinformation
This study investigates crustal deformation in Hong Kong using the Global Navigation Satellite System (GNSS) observations from 19 stations and a range of geophysical models. We examine horizontal and vertical land motions (VLM) recorded by GNSS from 2001

A research framework for seismic slip distribution inversion considering atmospheric effects and deformation field downsampling

International Journal of Digital Earth
Traditional Interferometric Synthetic Aperture Radar (InSAR) methods have difficulties in capturing deformation information of small and medium-sized earthquakes due to small surface deformation and atmospheric interference.

Fast, accurate solutions for curvilinear earthquake faults and anelastic strain [PDF]

, 2018
Imaging the anelastic deformation within the crust and lithosphere using surface geophysical data remains a significant challenge in part due to the wide range of physical processes operating at different depths and to various levels of localization that

Distribution of slip from 11 M_w > 6 earthquakes in the northern Chile subduction zone [PDF]

, 2006
We use interferometric synthetic aperture radar, GPS, and teleseismic data to constrain the relative location of coseismic slip from 11 earthquakes on the subduction interface in northern Chile (23°–25°S) between the years 1993 and 2000.

Multi-methodological approach for assessing surface faulting and paleoliquefaction history in central Italy: applicative implications for seismic microzonation studies in the Quaternary L’Aquila basin

Frontiers in Earth Science
Surface faulting and liquefaction are two earthquake-related effects to be considered in geological hazard assessment studies, particularly in application cases involving the construction or reconstruction of strategic buildings.

Unlocking the hidden secrets of the 2023 Al Haouz earthquake: Coseismic model reveals intraplate reverse faulting in Morocco derived from SAR and seismic data

International Journal of Applied Earth Observations and Geoinformation
The 2023 Mw 6.8 Al Haouz earthquake struck Morocco’s Atlas Mountains on September 8, causing over 3000 fatalities and extensive damage, revealing hidden seismic hazards in this slowly deforming region. Despite its impact, Al Haouz earthquake has received

Frictional experiments of dolerite at intermediate slip rates with controlled temperature: Rate weakening or temperature weakening? [PDF]

, 2011
A rotary shear apparatus has been newly set up in Chiba University which can control the temperature near a sliding surface, T_meas, up to 1000°C independently from slip rate, V.

A multilayer model of time dependent deformation following an earthquake on a strike-slip fault [PDF]

A multilayer model of the Earth to calculate finite element of time dependent deformation and stress following an earthquake on a strike slip fault is discussed. The model involves shear properties of an elastic upper lithosphere, a standard viscoelastic
