Source mechanisms of vulcanian eruptions at Mt. Asama, Japan, inferred from volcano seismic signals

Geological Society, London, Special Publications, 2008
Abstract During the 2004 Asama volcanic activity, five summit eruptions, accompanied by the broadband seismic signals, were observed. We re-analyse the broadband waveform data analysed by Ohminato et al. (2006) using relaxed restrictions.

Dual Infrasound Sources from a Vulcanian Eruption of Sakurajima Volcano Inferred from Cross-Array Observation

Seismological Research Letters, 2014
The study of volcano infrasound is becoming increasingly popular (Johnson and Ripepe, 2011; Fee and Matoza, 2013) with analysis of the recorded signals contributing to our understanding of eruption dynamics and enhancing capabilities in remote monitoring of volcanoes. Multiple studies have determined the source locations of the infrasound from volcanic

Mechanism of small vulcanian eruptions at Suwanosejima volcano, Japan, as inferred from precursor inflations and tremor signals

Bulletin of Volcanology, 2013
We examine precursory signals of vulcanian eruptions at Suwanosejima volcano, southwest of Japan, by deploying seismic and tilt stations close to the active crater to understand the shallow conduit processes just before explosions. Vulcanian eruptions at Suwanosejima for the period from October 2009 to 2011 are often preceded by a sudden cessation of ...

From Vulcanian explosions to sustained explosive eruptions: The role of diffusive mass transfer in conduit flow dynamics

Journal of Volcanology and Geothermal Research, 2006
Abstract Magmatic explosive eruptions are influenced by mass transfer processes of gas diffusion into bubbles caused by decompression.

On the occurrence of volcanic lightning during vulcanian eruptions at Sakurajima volcano, Japan

Volcanic eruptions are enigmatic, not in the least because of volcanic lightning during eruptions, which is still not fully understood. In an effort to better constrain conditions under which electrical discharges occur, we use data from a multicomponent geophysical network installed in 2019 at Sakurajima volcano, Japan.
