Rodingite‐Derived Melt as a Recipe for Ultra‐Calcic Magmas
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Rodingite is a high‐CaO rock formed by Ca‐rich fluid metasomatism on mafic protoliths. It typically occurs within serpentinite and represents an often‐overlooked constituent of the altered oceanic lithosphere that may be subducted into the mantle.

Segmented Moho Uplift and Implications for Magmatic Underplating Beneath the Datong Basin
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Understanding how the deep crust responds to coupled tectonic and magmatic processes is essential for deciphering intracontinental rifting. We apply high‐resolution passive‐source reverse time migration to teleseismic P‐wave receiver functions recorded by a dense seismic array to image the Moho beneath the Datong Basin. Our observations reveal

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract We present new results from ambient noise tomography and azimuthal anisotropy analysis of the DOMERAPI data set to investigate crustal structure beneath the Merapi‐Merbabu‐Telomoyo region in central Java. The 3D shear‐wave velocity (Vs) model reveals a prominent high‐Vs anomaly extending from south of Merapi through Merbabu to Telomoyo ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The mechanisms underlying the patchy distribution of forearc megathrust earthquakes and arc volcanoes in subduction zones remain poorly understood. Here we present a high‐resolution seismic tomographic model of the Central American subduction zone, derived from a joint inversion of local body‐wave and teleseismic Rayleigh‐wave data.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The role of inherited lithospheric structures in active rift seismicity and magma intrusion remains a key uncertainty in continental breakup dynamics. We investigate the January 2025 Northern Main Ethiopian Rift swarm using constrained 3‐D gravity inversion and D‐InSAR observations to characterize crustal architecture, seismicity, and active ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract SO2 flux and gas composition were measured during the 2021 flank eruption of Pacaya Volcano (Guatemala). The SO2 flux, measured with Tropomi, gradually rose from ∼2 to ∼30 kg/s over a 5 month period before the eruption. Field UV camera data showed that >95% of the SO2 was emitted from the summit crater.

Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...
