Imaging and seismic modelling inside volcanoes using machine learning

Scientific Reports, 2023
Despite advances in seismology and computing, the ability to image subsurface volcanic environments is poor, limiting our understanding of the overall workings of volcanic systems.

Volcanic Unrest at Taupō Volcano in 2019: Causes, Mechanisms and Implications

Geochemistry, Geophysics, Geosystems, 2021
Taupō volcano, New Zealand, is a large caldera volcano that has been highly active through the Holocene. It most recently erupted ∼1,800 years ago but there have been multiple periods of historic volcanic unrest.

High-frequency S and S-coda waves at ocean-bottom seismometers

Earth, Planets and Space, 2023
To clarify the characteristics of high-frequency (> 1 Hz) S and S-coda waves at ocean-bottom seismometers (OBSs), we analyzed seismograms observed at permanent OBSs and inland broadband seismometers around the Kii Peninsula in southwest Japan along the ...

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.

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.
