Testing Volcano Deformation Models Against 3D Seismic Reflection Imagery of Ancient Intrusions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Magma intrusion often drives uplift of the overburden and free surface. Analytical modeling of such surface uplift at active volcanoes allows us to estimate intrusion geometries and positions, as well as volume and pressure changes; these insights have proven critical to forecasting volcanic unrest and eruptions. However, it is rarely possible

From Collision to Subduction: Thermal‐Kinematic Inversions Constrain Plate Boundary Structure and Dip‐Slip Activity in Southwestern New Zealand

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Constraints on three‐dimensional fault system geometry and kinematics are required to understand both long‐term tectonics and contemporary seismic hazard. In many cases, these parameters must be inferred from a combination of different data or analyses.

Reconstructing Late Pleistocene to Prehistorical Holocene Geomagnetic Field Variations From La Palma Lava Flows (Canary Islands, Spain): Unraveling Viscous Components

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present new vector paleomagnetic data from 13 radiometrically dated lava‐flows in southern La Palma (Canary Islands) spanning from 1 to 56 ka, which covers most of the Late Pleistocene to prehistoric Holocene volcanic record in the island.

Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.
