Exploring the link between large earthquakes and magma transport at the onset of the Mayotte volcano-seismic crisis

open access: yesComptes Rendus. Géoscience, 2022
The archipelago of Comoros was generally considered a moderately seismic region. However, since May 2018, unusual seismicity has been observed off the east coast of Mayotte Island.

Geophysical characterization of hydrothermal systems and intrusive bodies, El Chichón volcano (Mexico) [PDF]

open access: yes, 2011
[1] The 1982 explosive eruptions of El Chichón volcano (Chiapas, Mexico) destroyed the inner dome and created a 1-km-wide and 180-m-deep crater within the somma crater.

Influence of Site Amplification Approaches in PSRA: Insights From Five Different Cities

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
Regional and national seismic hazard models used in probabilistic seismic risk analysis often rely on generalized proxy‐based site terms to account for ground shaking amplification. This can result in coarse representations of site response, which can introduce bias or additional uncertainty in the associated risk results.

The monitoring of seismic activity at Nyiragongo volcano through telemetered seismic network Goma Volcano Observatory (Democratic Republic of the Congo)

open access: yes, 2007
The eruption, in January 2002, of Mount Nyiragongo in eastern Congo, and the humanitarian disaster that followed in its wake, underlined the critical importance of accurate seismology to predict when such events will take place.

Revealing the Hydrothermal System of La Soufrière Volcano (Guadeloupe) Through Nodal Ambient Noise Tomography

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract La Soufri'ere de Guadeloupe is an active volcano of the Lesser Antilles Volcanic Arc. Its last eruption halted in 1977, yet hydrothermal activity has increased over recent years, raising summit instability hazards. The link between hydrothermal fluids and detachment landslide surfaces is well established and exacerbated by inflation ...

Correction to: Magnitude–frequency distribution of volcanic explosion earthquakes

open access: yesEarth, Planets and Space, 2017
Magnitude–frequency distributions of volcanic explosion earthquakes that are associated with occurrences of vulcanian and strombolian eruptions, or gas burst activity, are examined at six active volcanoes.

Subglacial volcano monitoring with fibre-optic sensing: Grímsvötn, Iceland

open access: yesVolcanica, 2023
We present a distributed acoustic sensing (DAS) experiment at Grímsvötn, Iceland. This is intended to investigate volcano-microseismicity at Grímsvötn specifically, and to assess the suitability of DAS as a subglacial volcano monitoring tool in general ...

CSDP: Seismology of continental thermal regime [PDF]

open access: yes, 1989
This is a progress report for the past one year of research (year 2 of 5-year project) under the project titled CSDP: Seismology of Continental Thermal Regime'', in which we proposed to develop seismological interpretation theory and methods applicable ...

Multi‐Scale Growth of an Mw 7.0 Earthquake via Hierarchical Cascading Rupture From an Mw 3.8 Repeating Event

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract To understand what governs earthquake size, we investigated the 2021 Mw 7.0 Japan Trench earthquake, which began near a nest of repeating earthquakes. High‐precision hypocenter relocation and P‐waveform correlation show that the mainshock initiated nearly identically to Mw 3.8 repeaters.

Lava production at Soufriere Hills Volcano, Montserrat: 1995-2009 [PDF]

open access: yes, 2010
[1] We estimate that about 1 km3 of andesitic lava has been produced at Soufrière Hills Volcano, Montserrat from 1995 to 2009. There were three major episodes of extrusion, each lasting about 2 to 3.5 years and producing about 280 to 340 M m3 of lava ...
