Triggered seismicity associated with the 1990 Nicoya, Costa Rica, M-w=7.0 earthquake [PDF]
, 2009 The 25 March 1990 (M-w = 7.0) subduction megathrust earthquake that occurred offshore the Nicoya Peninsula, Costa Rica, produced a large number of aftershocks on the subduction plate interface as expected and preceded an unusual sequence of earthquakes ...

Thermally Activated Static Friction Can Explain Earthquake Interactions
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Unlike meteorological hazards, tectonic earthquakes remain hardly predictable, reinforcing their deadly character. This relates to an out‐of‐equilibrium, intermittent dynamic associated with a strong time asymmetry, with few and non‐systematic foreshocks sometimes preceding large earthquakes, while aftershocks are ubiquitous and have been ...

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 ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.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 ...

Imaging topographic growth by long-lived postseismic afterslip at Sefidabeh, east Iran [PDF]
, 2014 This paper describes observations and models of the postseismic deformation following the 1994 Sefidabeh earthquake sequence in east Iran, which shed light on the nature of the earthquake cycle and the mechanisms of topographic growth in the region ...

Rapid Earthquake Magnitude Estimation for Local Early Warning Systems Using Seismogeodesy
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Rapid and accurate estimation of earthquake moment magnitude is crucial for early warning systems, for alerting coastal populations vulnerable to tsunamigenic hazards. Most seismic‐based estimation approaches introduce time delays that limit applicability near the source, while geodetic approaches have been limited to empirical scaling ...

Stress transfer and strain rate variations during the seismic cycle [PDF]
, 2004 The balance of forces implies stress transfers during the seismic cycle between the elastobrittle upper crust and the viscoelastic lower crust. This could induce observable time variations of crustal straining in the interseismic period.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract We re‐examine the aftershock sequence of the Mw 8.8 Maule earthquake in south‐central Chile to understand how seismicity, magnitude‐frequency distribution, and fault structure vary along the rupture zone. Using the International Maule Aftershock Deployment (IMAD) data set, we analyze 10 months of continuous data from approximately 156 ...

Coseismic Slip and Afterslip of the Great M_w 9.15 Sumatra–Andaman Earthquake of 2004 [PDF]
, 2007 We determine coseismic and the first-month postseismic deformation associated with the Sumatra–Andaman earthquake of 26 December 2004 from near- field Global Positioning System (GPS) surveys in northwestern Sumatra and along the Nicobar-Andaman islands ...
