Pressurized magma storage in radial dike network beneath Etna volcano evidenced with P-wave anisotropic imaging [PDF]

Communications Earth & Environment
Investigating crustal stress beneath volcanoes is critical to understanding the dynamics of eruptions. To this end, seismology represents a powerful monitoring tool.

Giuseppe Imbò and his contribution to volcano seismology

Annals of Geophysics, 1999
Together with Fusakichi Omori and Kenzo Sassa, Giuseppe Imbò is one of the founders of volcano seismology. Imbò's novel idea in volcanic tremor analysis was the introduction of what he called "numeri indici dell'intensità eruttiva" (numerical indices of ...

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 ...
