Automatic Earthquake Declustering Using the Nearest‐Neighbor Distance
Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract In the widely adopted description of seismic occurrence, earthquakes are categorized as either background or triggered events. In this work, we present a fully automated, non‐parametric algorithm for distinguishing between these two categories, a process known as seismic declustering, based on the widely used nearest‐neighbor (NN) metric.

Progress in Earth and Planetary Science, 2019 On December 7, 2012, an earthquake occurred within the Pacific Plate near the Japan Trench, which was composed of deep reverse- and shallow normal-faulting subevents (Mw 7.2 and 7.1, respectively) with a time interval of ~10 s. It had been known that the

The Age and Composition of the Voyager Seamounts: Evidence for a Long‐Lived Marquesas Mantle Source
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract We present new observations on the dynamics and locations of deep mantle reservoirs derived from the ages and compositions of Voyager Seamount Chain lava flows. The previously unexplored Voyager Seamount Chain trends NW–SE between the Mid‐Pacific Mountains and the Northwestern Hawaiian Ridge.

What controls the occurrence of shallow intraplate earthquakes? [PDF]
Earth, Planets and Space, 2014 We simulated the occurrence of both intraplate and interplate earthquakes in a simple spring-slider-dashpot model that includes both types of earthquake faults. We found that recurrence intervals of intraplate earthquakes are not controlled by the velocity of the relative plate motion but by the viscosity in the ductile fault zone, the coefficients of ...

Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

Comparative analysis of the seismic hazard of Central China [PDF]
, 2008 Seismic hazard assessment is globally recognised as a tool in identifying levels of earthquake ground shaking within an area. However, methodologies for seismic hazard calculation are wide ranging and produce variations in results and maps.

Special Publications, 2015 The prehistoric Egiin Davaa earthquake rupture is well-preserved in late Quaternary deposits within the Hangay Mountains of central Mongolia. The rupture is expressed by a semi-continuous 80 km-long topographic scarp.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Intraplate volcanism has long been linked to deep mantle plumes. However, recent studies showed that intraplate magmatism can originate from transition zone dynamics, where lower‐mantle plumes might be ponding, creating a Thermal Boundary Layer (TBL).
