Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.

Improving the Knowledge on Seismogenic Sources in the Lower Tagus Valley for Seismic Hazard Purposes [PDF]

open access: yes, 2012
The Lower Tagus Valley, that includes the metropolitan area of Lisbon, has been struck by several earthquakes which produced significant material damage and loss of lives. Their exact location remains unknown.

A New Surface Rupture of the 1556 Huaxian M ∼ 8.5 Earthquake Revealed by Rock Surface Luminescence Dating of a Bedrock Fault Scarp and Colluvial Wedges

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Bedrock fault scarps and their associated colluvial wedges provide key evidence for reconstructing paleoearthquakes. We apply rock surface luminescence dating to a bedrock scarp on the Huashan fault in central China, using OSL‐depth profiles (DPs) from multiple heights. Results reveal two coseismic displacements of 6.8 and >1.0 m.

Nonvolcanic tremor observed in the Mexican subduction zone [PDF]

open access: yes, 2008
Nonvolcanic tremor (NVT) activity is revealed as episodes of higher spectral amplitude at 1–8 Hz in daily spectrograms from the continuous seismological records in Guerrero, Mexico.

Seismogenic structures activated during the 1987 seismic sequences along the Adriatic coast [PDF]

open access: yesGeophysical Journal International, 1992
SUMMARY In order to obtain a better spatial definition of the structures which were activated during the Marche Adriatic coast seismic sequences in summer 1987 we relocated the earthquakes epicentres by means of an original computer code based on the ‘joint hypocentre determination’ technique.

Coulomb Pre‐Stress Changes Modulate Coseismic Rupture Kinematics of the 2025 Mw7.7 Myanmar Earthquake Revealed by Space Geodesy

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract We estimate the fault geometry and coseismic slip of the 2025 Myanmar earthquake using multi‐source satellite observations, revealing a nine‐segment rupture structure that transitions from eastward‐dipping in the north to westward‐dipping in the south, with peak slip of ∼6 m and negligible shallow slip deficit.

Interpreting intraplate tectonics for seismic hazard : a UK historical perspective [PDF]

open access: yes, 2012
It is notoriously difficult to construct seismic source models for probabilistic seismic hazard assessment in intraplate areas on the basis of geological information, and many practitioners have given up the task in favour of purely seismicity-based ...
