Coseismic deformation obtained from surface ocean currents in a flat bottom ocean

Abstract Seismic tsunami sources are often inferred by inverting a combination of data from onshore and offshore instruments. However, these measurements are often geographically sparse and far from the source, leading to declining resolutions in some areas, especially near the shallower parts of the rupture.

Influence of the Loading Stiffness on Sheared Granular Fault Gouge, and Applicability to Slip‐Weakening Theory

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Tectonic faults can slip in a spectrum of fault slip behaviors, from aseismic slip and slow ruptures to elasto‐dynamic earthquakes. Following frictional theory, laboratory experiments have shown that the basic ingredient that may control this transition is the interaction between the fault stiffness and the surrounding elastic medium.

On the evolution of elastic properties during laboratory stick-slip experiments spanning the transition from slow slip to dynamic rupture [PDF]

, 2016
The physical mechanisms governing slow earthquakes remain unknown, as does the relationship between slow and regular earthquakes. To investigate the mechanism(s) of slow earthquakes and related quasi-dynamic modes of fault slip we performed laboratory ...

Poroelastic Bulk Controls on Shear Localization in Fault Gouge During Earthquake Rupture: Insights From a Hybrid Numerical Framework

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Seismic ruptures that extend over kilometers along faults originate in shear zones only millimeters thick. We present a hybrid numerical framework coupling the spectral boundary integral method (SBIM) for the poroelastic bulk with a staggered‐grid finite difference method (FDM) for the fault gouge.

Buried shallow fault slip from the South Napa earthquake revealed by near-field geodesy. [PDF]

, 2017
Earthquake-related fault slip in the upper hundreds of meters of Earths surface has remained largely unstudied because of challenges measuring deformation in the near field of a fault rupture.

Fault Kinematics of the 2019–2026 Puerto Rico Earthquake Sequence: Conjugate Faulting Within a Zone of Oblique Subduction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...

Northward rupture and early afterslip of two graben-bounding normal faults during the 2025 Dingri earthquake of Tibet

Communications Earth & Environment
The Mw 7.0 Dingri earthquake, the largest documented normal-faulting event in southern Tibet, struck within the NS-trending Dinggye-Xainza Rift system. Here we combine field observations, high resolution optical and synthetic aperture radar imagery and ...

Evidence for Anthropogenic Surface Loading as Trigger Mechanism of the 2008 Wenchuan Earthquake

, 2011
Two and a half years prior to China's M7.9 Wenchuan earthquake of May 2008, at least 300 million metric tons of water accumulated with additional seasonal water level changes in the Minjiang River Valley at the eastern margin of the Longmen Shan.

Asperities and barriers on the seismogenic zone in North Chile: state-of-the-art after the 2007 Mw 7.7 Tocopilla earthquake inferred by GPS and InSAR data [PDF]

, 2010
The Mw 7.7 2007 November 14 earthquake had an epicentre located close to the city of Tocopilla, at the southern end of a known seismic gap in North Chile. Through modelling of Global Positioning System (GPS) and radar interferometry (InSAR) data, we show
