Satellite Geodesy Reveals Shallow, Transient Magma Intrusions at Sotará Volcano, Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Sotará is a little‐known andesitic‐dacitic stratovolcano in southwestern Colombia. Although there are no recorded historical eruptions, the volcano shows clear evidence of geothermal activity, deformation, and volcano‐tectonic seismicity. Its remote location and rugged terrain pose challenges for access and routine monitoring.

Observations of Small‐Scale Heterogeneity in the Upper Mantle Beneath Old Oceanic Lithosphere

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract We present tomographic images of the velocity structure of the upper mantle beneath old (∼90 ${\sim} 90$ Ma) oceanic lithosphere, derived from arrival time measurements of teleseismic body waves recorded by ocean‐bottom seismometers. Differential travel time measurements on P, S, and SKS body waves across a wide range of frequency bands show ...
