Volcano Seismology From Around The World: Case Studies From Mount Pinatubo (Philippines) Galeras (Colombia), Mount Wrangell And Mount Veniaminof (Alaska) [PDF]

, 2005
Dissertation (Ph.D.) University of Alaska Fairbanks, 2005A compilation of research papers in volcano seismology is presented: (1) to study the configuration of magma systems beneath volcanoes, (2) to describe unexpected effects of the shaking from a ...

Pervasively Thin Anatolian Lithosphere With Elevated Upper Mantle Temperatures in the East: Insights From Bayesian Thermo‐Compositional Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Uplift and widespread Late Miocene‐present magmatism in Anatolia are commonly attributed to lithospheric thinning, possibly facilitated by the arrival of hot mantle plume material. There are various lines of evidence for thin present‐day lithosphere, but the spatial extent and degree of lithospheric thinning and the underlying mantle ...

A new consistent and high-precision earthquake catalogue for the Taupō Volcanic Zone, New Zealand

Seismica
The Taupō Volcanic Zone is a ~300 km long, volcanically active region in the North Island of Aotearoa New Zealand. As well as hosting numerous active volcanoes, it is also one of the most seismically active parts of the country.

Development of an early-warning system for monitoring remote volcanoes

Annals of Geophysics, 1996
Many andesitic volcanoes are quiescent for long time periods: usually (but not always) an increase in seismic activity and in deformation precedes an eruption by a few months or a few days.

Microgravity Measurements Spanning 2019–2022 Indicate No Change in Magma Supply or Storage During Kīlauea's Reawakening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract After more than 2 years of quiescence following its major 2018 flank lava effusion and summit caldera collapse, Kīlauea, Hawaiʻi, returned to frequent eruptive activity in late 2020. Microgravity measurements from the summit region in 2019 and 2022 span this reawakening and indicate a gravity increase of up to hundreds of microgals near the ...

Submarine seismicity monitoring with distributed acoustic sensing near Santorini and Kolumbo Volcano

Seismica
Submarine volcanoes and faults pose hazards to nearby populated islands, yet their inaccessibility limits monitoring efforts. The Christiana-Santorini-Kolumbo volcanic field is capable of generating devastating eruptions, earthquakes and tsunamis.

Analysis and quasistatic FE modeling of long period impulsive events associated with explosions at Stromboli volcano (Italy)

Annals of Geophysics, 1999
Broadband seismic measurements performed in 1995 and 1996 in the summit region of Stromboli are analyzed. The experiment in 1995 used an array of four Guralp seismometers and one Wielandt-Streckeisen seismometer.

Episodic Seismicity Bursts Driven by Magma Intrusion During the 2025 Santorini‐Amorgos Seismic Crisis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The 2025 Santorini–Amorgos seismic crisis in Greece had an exceptionally large number and sustained rate of moderate‐sized earthquakes. We used a machine‐learning‐based earthquake monitoring workflow to detect and relocate 66,109 earthquakes and interpret the results in the context of global analogs.

High‐Resolution Body‐Wave Tomography of Kı̄lauea's Summit Magma Storage System From a Dense Passive and Active Source Experiment

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Imaging magma storage beneath active calderas requires resolving crustal structure at scales comparable to those of individual reservoirs. To identify potential reservoirs beneath Kı̄lauea, Hawai'i, we conducted a hybrid seismic experiment at its summit for 37 days in 2023 that combined more than 1,800 three‐component nodal seismometers with ...
