Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Understanding the cause of spatial variations in seismicity is crucial for comprehending the physics governing earthquake activity. Off Iwate, in the northern Japan Trench subduction zone, the plate boundary can be divided into three distinct zones based on depth‐dependent slip regimes: the slow earthquake, asperity, and stable creeping zones.

Recent Seismic Activity in the Azores Region [PDF]
, 2008 This seismic activity in the Azores Region is characterized by sequences of low-magnitude events, usually with epicenter off-shore. These seismic sequences are sometimes triggered by larger events, felt by the population, that could produce significant ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract We present a high‐resolution local earthquake tomography model that constrains the distribution of hydration and dehydration processes within the subducting Nazca slab beneath Northern Chile. We image a distinct downdip transition from high Vp/Vs (∼1.75) over low Vp/Vs (∼1.65) to a homogeneously high Vp/Vs slab at depths of ≥ ${\ge} $85 km ...

Seismological aspects of the Cairo earthquake, 12th October 1992
Annals of Geophysics, 2000 On 12 October 1992 a significant earthquake (MB = 5.8) occurred southwest of Cairo in the vicinity of the Dahshour region. For the mainshock, an average moment release M 0 = 9.70E17 n-m; a fault length = 13.8 km; an average displacement = 0.22 m; a ...

The mechanisms of spatial and temporal earthquake clustering
, 2009 The number of earthquakes as a function of magnitude decays as a power law. This trend is usually justified using spring-block models, where slips with the appropriate global statistics have been numerically observed.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Recent megathrust earthquakes preceded by slow slip events highlight static stress transfer as a key triggering mechanism. However, there are limited insights into the interplay between static stress transfer and elevated fluid pressure before earthquake triggering.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Геодинамика и тектонофизика, 2015 The cataclastic method developed by Yu.L. Rebetsky is applied to reconstruct the recent field of stresses related to aftershock sequences of earthquakes that occurred in the Altai-Sayan mountainous region, specifically the Altai earthquake of 27 ...

Crustal Heat Flow Drives the Earthquake Magnitude Distribution
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Earthquake magnitude‐frequency distributions exhibit significant space‐time variations, which can provide critical insights into the physical processes driving seismicity. Understanding these variations is crucial for assessing seismic hazards and uncovering the physical processes driving earthquakes.
