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

QuakeMigrate: a Python Package for Automatic Earthquake Detection and Location Using Waveform Migration and Stacking

Seismica
QuakeMigrate is a modular, open-source Python package providing a framework to efficiently and automatically detect and locate microseismicity. From raw seismic waveforms and a modest number of physically meaningful inputs and tuneable parameters, it ...

Crustal Shear‐Wave Velocity and Azimuthal Anisotropy Imaging Reveals the Merapi‐Merbabu‐Telomoyo Volcanic Chain, Central Java

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 ...

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 ...

Structural Heterogeneity Shapes Segmentation of Megathrust Earthquakes and Volcanism in Central America

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.

The Role of Tectonic Inheritance in Active Rift Seismicity and Magmatism: Constraints From 3‐D Gravity Inversion and D‐InSAR Modeling of the 2025 Fentale Swarm, Ethiopia

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 ...

Near Vent Seismicity at the Tour Eiffel Vent Site, Lucky Strike Hydrothermal Field, Mid-Atlantic Ridge

Seismica
Secondary hydrothermal circulation is created by local entrainment of cold seawater into the shallow subseafloor by the intense discharge of high temperature fluids through focused vents at black smoker hydrothermal fields.

Near‐Field Acoustic and Gravity Wave Modes in the Ionosphere Triggered by Ground Motion and Tsunami During the 2024 Mw7.4 Hualien Earthquake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The interaction between the atmosphere and other components of the Earth system, such as the solid Earth and the oceans, remains an open and active area of research. In particular, the dynamic response of the ionosphere to forcing from below, such as earthquakes and tsunamis, is not yet fully understood.

The critical role of volcano monitoring in risk reduction [PDF]

, 2008
Data from volcano-monitoring studies constitute the only scientifically valid basis for short-term forecasts of a future eruption, or of possible changes during an ongoing eruption.

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.
