Location and Felt Reports for the 25 April 2010 mbLg 3.9 Earthquake Near Alice, Texas: Was it Induced by Petroleum Production? [PDF]

, 2012
This study examines seismograms and felt reports for the 25 April 2010 Alice, Texas, earthquake and explores its possible relationship with gas and oil production in the Stratton field. We identified P arrivals at seven broadband stations situated within

Fault Roughness Controls Seismicity Front Migration During Fluid Injection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The increasing occurrence of injection‐induced earthquakes has raised public concern and highlighted the importance of understanding subsurface processes and mechanisms to assess induced seismic hazards and risks. We develop a simple physics‐based model to investigate how fault roughness controls the migration of seismicity during fluid ...

Statistical properties of seismicity of fault zones at different evolutionary stages [PDF]

, 2007
We perform a systematic parameter space study of the seismic response of a large fault with different levels of heterogeneity, using a 3-D elastic framework within the continuum limit.

Plate Interactions and Mantle Flows Beneath the Caribbean and Adjacent Regions Revealed by P‐Wave Anisotropic Tomography

Tectonics, Volume 45, Issue 3, March 2026.
Abstract We determine the first P‐wave azimuthal and radial anisotropy tomography beneath the Caribbean and its adjacent regions. The Cocos and Atlantic Plates are imaged as high‐velocity (high‐V) zones down to ∼1,600 km depth and they have subducted independently beneath the Caribbean Plate.

hypoDD-A Program to Compute Double-Difference Hypocenter Locations [PDF]

Open-File Report, 2001
HypoDD is a Fortran computer program package for relocating earthquakes with the double-difference algorithm of Waldhauser and Ellsworth (2000). This document provides a brief introduction into how to run and use the programs ph2dt and hypoDD to compute double-difference (DD) hypocenter locations.

Double-difference Relocation of the Aftershocks of the Tecomán, Colima, Mexico Earthquake of 22 January 2003 [PDF]

, 2010
On 22 January 2003, the M_w = 7.6 Tecomán earthquake struck offshore of the state of Colima, Mexico, near the diffuse triple junction between the Cocos, Rivera, and North American plates. Three-hundred and fifty aftershocks of the Tecomán earthquake with

Seismicity and Seismotectonics in the Cantabrian‐Pyrenean Zone (N Spain) Using a Dense Temporary Network of Broadband Seismic Stations

Tectonics, Volume 45, Issue 3, March 2026.
Abstract Earthquakes in intraplate regions are often scattered and difficult to associate with specific geological structures, requiring detailed surveys to identify active faults. Improving knowledge of local seismicity in these areas is essential for accurate seismic hazard assessment and for safe planning of economic activities that could affect ...

The 13 November 2016 Kaikoura, New Zealand earthquake: rupture process and seismotectonic implications

Earth and Planetary Physics, 2018
The 13 November 2016 Kaikoura earthquake occurred in the northeastern coastal region of the South Island, New Zealand. The Mw 7.8 mainshock generated a complex pattern of surface ruptures, and was followed within about 12 hours by three moderate shocks ...
