Ductile Extrusion Triggered by Continental Collision in NE Brazil

Terra Nova, Volume 38, Issue 4, Page 266-277, August 2026.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Future Global Warming Constrained by Observed AMOC Strength

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The spread in projected global warming across the Coupled Model Intercomparison Project (CMIP) models under idealized forcing has been statistically linked to the inter‐model difference in climatological Atlantic Meridional Overturning Circulation (cAMOC), yet the underlying physical mechanisms remain unclear. Here, we analyze realistic future

High‐Resolution Imaging of a Distant M6 Intermediate‐Depth Earthquake Using Ocean‐Bottom DAS and Seismic Network

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Distributed Acoustic Sensing (DAS) provides dense, wide‐aperture observations potentially ideal for imaging earthquake rupture processes. By combining data from a ∼450 km‐long seafloor DAS array offshore Chile and a conventional seismic network, we image an Mw 6.0 intermediate‐depth earthquake ∼400 km away in Argentina, achieving km‐scale ...

Insights Into Magmatic Degassing, Hydrothermal Dynamics, and Eruption Precursors From Long Term SO2 Emission Monitoring at Whakaari/White Island, New Zealand

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Long‐term SO2 emission rate time series are critical for deciphering the subsurface processes regulating open‐vent volcanoes, yet extracting cyclical drivers from continuous degassing records remains challenging. We analyze a 14‐year (2006–2020) SO2 emission rate data set from Whakaari/White Island, New Zealand, identifying five chronological ...

From Magma to Atmosphere: Halogen Fluxes During Volcanic Eruptions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Volcanic eruptions release significant quantities of volatile elements into the atmosphere and stratosphere. Plinian eruptions are particularly efficient at dispersing these elements due to their large magma volumes and high eruption columns.

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...
