Listening carefully: unique observations of harmonic tremor at Lascar volcano, Chile

open access: yesAnnals of Geophysics, 1999
During the deployment of Proyecto de Investigación Sismológica de la Cordillera Occidental 94 (PISCO'94) in the Atacama Desert of Northern Chile, a broadband seismic station and a network of three short-period three-component stations were installed ...

Imaging Torfajökull’s volcano with seismic interferometry and surface-wave tomography [PDF]

open access: yes, 2019
Torfajökull volcano, Iceland, has not erupted since 1477. However, intense geothermal activity, deformation, and seismicity suggest a long‐lasting magmatic system.

The Stromboli Volcano landslides of December 2002: A seismological description [PDF]

open access: yesGeophysical Research Letters, 2004
We analyse seismograms of the slump episodes at Stromboli on December 30, 2002. Using a simple single force model, we estimate the volume involved in the individual subevents and attempt a chronological reconstruction of the whole process. Our results indicate the occurrence of two main events that could be interpreted as a submarine slump, which ...

Back‐Projection Imaging of Extended, Diffuse Sources of Volcano‐Tectonic Seismicity During June 2010 at Sierra Negra Volcano, Galápagos

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Seismic signals generated by subsurface volcano‐tectonic processes commonly have low signal‐to‐noise ratios that make it difficult to resolve both 3‐D subsurface structures and seismic source locations using established seismic imaging methods (e.g ...

Foundations for Forecasting: Defining Baseline Seismicity at Fuego Volcano, Guatemala

open access: yesFrontiers in Earth Science, 2018
Accurate volcanic eruption forecasting is especially challenging at open vent volcanoes with persistent low levels of activity and relatively sparse permanent monitoring networks.

Single-Station Seismo-Acoustic Monitoring of Nyiragongo's Lava Lake Activity (D.R. Congo)

open access: yesFrontiers in Earth Science, 2018
Since its last effusive eruption in 2002, Nyiragongo has been an open-vent volcano characterized by the world's largest persistent lava lake. This lava lake provides a unique opportunity to detect pressure change in the magmatic system by analyzing its ...

Volcanic and Tectonic Sources of Seismicity Near the Tanaga Volcanic Cluster, Alaska

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Tanaga Island in the Central Aleutian Islands includes four stratovolcanoes: Sajaka, Tanaga, and East Tanaga in the northwest, and Takawangha in the central part of the island. Of these volcanoes, only Tanaga has a confirmed record of historical eruptive

Studies in Fluid Dynamics as Applied to Seismology and Volcanology [PDF]

open access: yes, 2001
This thesis addresses three problems in seismology and volcanology by applying fluid dynamical theories that have been developed for engineering applications. Fault zones are proposed to operate analogously to journal bearings.
