Branched Conduit Structure Beneath the Active Craters of Sakurajima Volcano Inferred From Muography

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.
Abstract Observing in‐conduit physical mechanism underlying the switching of eruptive activity between the craters of multi‐vent volcanoes could contribute to hazard assessment at these complex volcanic edifices. We performed monitoring of mass density changes beneath two active craters of Sakurajima volcano in Kyushu, Japan between September 2018 and ...

Time‐Resolved Trigger Processes Leading to the Plinian Eruptions at Sakurajima Volcano, Japan

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.
Abstract Mafic magma recharge of crustal reservoirs and subsequent magma mixing has been considered a direct trigger of volcanic eruptions. However, although recharge frequently occurs in many active volcanoes, it rarely leads to an eruption immediately, making its role as a trigger ambiguous.

Source process of Vulcanian explosion earthquakes at Sakurajima volcano, Japan, derived from seismic waveform inversion analysis in the very-long and long period bands and infrasound signals

Earth, Planets and Space
Eruption models developed using the waveform inversion method for explosion earthquakes differ across studies, and a unified model has not been established. Here, Vulcanian eruption processes of the Sakurajima volcano, Japan, were clarified using seismic

Twenty years of explosive-effusive activity at El Reventador volcano (Ecuador) recorded in its geomorphology

Frontiers in Earth Science
Shifts in activity at long-active, open-vent volcanoes are difficult to forecast because precursory signals are enigmatic and can be lost in and amongst daily activity.
