Complex Shear‐Wave Splitting Behavior in the Northern Andes and Possible Implications for Mantle Flow Around the Caldas Tear

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract We investigate shear‐wave splitting of SKS and SKKS phases from teleseismic earthquakes to study the anisotropic structure of the lithosphere and upper mantle beneath the Colombian Andes. This area is shaped by complex interactions between the subducting Nazca and Caribbean plates beneath the South American plate. A recent broadband deployment

Spatiotemporal Modeling of Lava Dome Evolution of Mt. Mayon during its 2023 Eruption using Remote Sensing Data [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Numerous lava dome construction and destruction processes were observed during the 2023 Mayon Volcano activity from 08 June until 08 December. Studying the lava dome development cycle of active volcanoes similar to Mayon Volcano is crucial because ...

Magma migration below Tancítaro and Paricutin volcanoes revealed by seismology

Geophysical Journal International
SUMMARY In this study, we analyse the 2020 seismic swarm that lasted two months and occurred between the Tancítaro and the Paricutin volcanoes in the Michoacán Guanajuato Volcanic Field, Mexico. We developed a new method to automatically detect and locate about 100 000 earthquakes, enabling us to track the magma migration through narrow ...

Along‐Strike Seismic Structure of the Andreanof Aleutian Arc Segment and Implications for the Formation of Continental Crust

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Crust formed in volcanic arcs is accreted to continents over geologic time, serving as the source material for new continental crust in Earth's present and recent past. Geochemically, arcs are found to be significantly more mafic than bulk continental crust.

Detection and Location of Volcano-Tectonic Earthquakes

Volcanic eruptions are one of the most hazardous natural disasters on Earth. With the increasing rate of development of areas on and around volcanoes, more people and property are at risk of volcanic activity.

Trans-crustal magma plumbing system of Kirishima Volcanic Complex as inferred from dense broadband magnetotelluric observations

Earth, Planets and Space
To investigate the magma plumbing system of the Kirishima Volcanic Complex (KVC), we conducted a broadband magnetotelluric (MT) survey over an expanded area of approximately 60 × 60 km, including the region around Shinmoe-dake volcano, which recently ...

Hydrological Impact of Earthquakes on Reverse and Normal Faults: Results From Numerical Models

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract I investigate earthquake‐induced hydrological signals related to poroelastic deformation, thermal pressurization, fault‐zone dilatancy and rupture of a pressurized reservoir at depth. This is performed using a two dimensional plane strain model that simulates ruptures on reverse and normal faults governed by rate‐and‐state friction coupled to ...
