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 ...

The Significance of Inherited Crustal Thickening in Surface Uplift of Hangai Dome in Central Mongolia

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The Hangai Dome in central Mongolia represents one of the most prominent intracontinental uplifts, yet the relative contributions of crustal and mantle dynamics in sustaining its high topography remain unresolved. Here we jointly invert Rayleigh wave dispersion and receiver function data to constrain crustal and uppermost mantle structures ...

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 ...

Magma migration below Tancítaro and Paricutin volcanoes revealed by seismology

Geophysical Journal International
SUMMARY In this study, we analyse the 2020 seismic swarm that lasted two months and occurred between the Tancítaro and the Paricutin volcanoes in the Michoacán Guanajuato Volcanic Field, Mexico. We developed a new method to automatically detect and locate about 100 000 earthquakes, enabling us to track the magma migration through narrow ...

Magma Pathways Beneath the Klyuchevskoy Volcanic Group, Kamchatka, Revealed by a Machine‐Learning‐Based Earthquake Catalog

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Klyuchevskoy Volcanic Group (KVG) is one of the world's largest clusters of subduction‐zone volcanoes and hosts a complex trans‐crustal magmatic system. Using a machine‐learning–based detection workflow applied to data from the KISS seismic experiment in 2015–2016, we obtained an enhanced earthquake catalog for KVG volcano‐magmatic activity ...

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.

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.

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
