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.

Spatiotemporal Modeling of Lava Dome Evolution of Mt. Mayon during its 2023 Eruption using Remote Sensing Data [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Numerous lava dome construction and destruction processes were observed during the 2023 Mayon Volcano activity from 08 June until 08 December. Studying the lava dome development cycle of active volcanoes similar to Mayon Volcano is crucial because ...

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‐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.

Deep‐Learning‐Based Phase Picking for Volcano‐Tectonic and Long‐Period Earthquakes

Geophysical Research Letters
The application of deep‐learning‐based seismic phase pickers has surged in recent years. However, the efficacy of these models when applied to monitoring volcano seismicity has yet to be fully evaluated.

Lithospheric geotherm and basalt assemblage beneath Nemrut and Suphan volcanoes (East Anatolia)

Volcanica
Understanding volcanic processes including eruption mechanisms depends on knowledge of temperature and chemical compo- sition (thermochemical structure) of the crust and the upper mantle. This study applies an integrated geophysical-petrological modeling

Migration of Seismicity from the Mantle to the Upper Crust Beneath Harrat Lunayyir Volcanic Field, Saudi Arabia

Seismica
Harrat Lunayyir is a volcanic field in Saudi Arabia that experienced a Mw~5.4 earthquake driven by an upper-crustal dike intrusion in May 2009. This volcanic field has exhibited numerous forms of volcanic seismicity both prior to and since the 2009 dike
