A Deep Active Learning Approach to the Automatic Classification of Volcano-Seismic Events

Frontiers in Earth Science, 2022
Volcano-seismic event classification represents a fundamental component of volcanic monitoring. Recent advances in techniques for the automatic classification of volcano-seismic events using supervised deep learning models achieve high accuracy. However,

Investigating potential icequakes at Llaima volcano, Chile

Volcanica, 2020
Glacially- and magmatically-derived seismic events have been noted to heavily overlap in characteristics, thus there exists the potential for false-alarms or missed warnings at ice-covered volcanoes. Here we present the first study to specifically target

The recent seismicity of Mt. Vesuvius: inference on seismogenic processes

Annals of Geophysics, 2013
We have analyzed the recent seismicity of Mt. Vesuvius, with particular emphasis on the period 1999-2012. Since 1972 continuous observations with electromagnetic seismometers allowed the compilation of a detailed earthquake catalogue for the station OVO.

Crustal structure below Popocat\'epetl Volcano (Mexico) from analysis of Rayleigh waves [PDF]

, 2007
An array of ten broadband stations was installed on the Popocat\'epetl volcano (Mexico) for five months between October 2002 and February 2003. 26 regional and teleseismic earthquakes were selected and filtered in the frequency time domain to extract the

The 2018 Hokkaido Eastern Iburi earthquake (M JMA = 6.7) was triggered by a strike-slip faulting in a stepover segment: insights from the aftershock distribution and the focal mechanism solution of the main shock

Earth, Planets and Space, 2019
The Hokkaido Eastern Iburi earthquake (M JMA = 6.7) occurred on September 6, 2018, in the Hokkaido corner region where the Kurile and northeastern Japan island arcs meet.

Volcanic earthquake catalog enhancement using integrated detection, matched-filtering, and relocation tools

Frontiers in Earth Science, 2023
Volcanic earthquake catalogs are an essential data product used to interpret subsurface volcanic activity and forecast eruptions. Advances in detection techniques (e.g., matched-filtering, machine learning) and relative relocation tools have improved ...

An analytical model for gas overpressure in slug-driven explosions:insights into Strombolian volcanic eruptions [PDF]

, 2012
Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.

A preliminary survey of the broadband seismic wavefield at Puu Oo, the active vent of Kilauea volcano, Hawaii

Annals of Geophysics, 1996
The seismic wavefield near an active volcanic vent consists of superimposed signals in a wide range of frequency bands from sources inside and outside the volcano.

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

Annals 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 ...
