Vulcanian eruptions at Sakurajima Volcano: geophysical data, numerical modelling, and petrological evidence
We investigated the magma conduit system beneath three active craters that have repeatedly generated Vulcanian eruptions at Sakurajima Volcano,...

Tephra segregation profiles based on disdrometer observations and tephra dispersal modeling: Vulcanian eruptions of Sakurajima volcano, Japan
The profile of tephra concentration along a volcanic plume (i.e., the tephra segregation profile) is an important source parameter for the simulation...

The pivotal role of Vulcanian activity in ending the explosive phase of rhyolitic eruptions: the case of the Big Obsidian Flow eruption (Newberry Volcano, USA)
Explosive volcanism produces myriad hazards from pyroclastic flows to widespread ejecta dispersal. Effusive eruptions can emit noxious, damaging...

Vulcanian eruption processes inferred from volcanic glow analysis at Sakurajima volcano, Japan
Volcanic glow, which is often observed at active craters during nighttime, contains information on high-temperature zones deep in the crater that are...

Mechanism of the historical and the ongoing Vulcanian eruptions of Ebeko volcano, Northern Kuriles
Ebeko is one of the most active volcanoes of the Kurile island arc, producing frequent mild Vulcanian explosions with eruption clouds up to 5 km...

The sequence of the 2017–2018 eruptions and seismo-acoustic activity at Kirishima volcano group
Kirishima volcano consists of more than 20 eruptive centers. Among them, Shinmoe-dake had magmatic eruptions in October 2017 and March 2018....

Long-lasting, small-to-moderate eruptions at composite volcanoes: reconstructing the largest eruption of Mt. Ruapehu (New Zealand) of the last two millennia
Small-to-moderate explosive eruptions involve VEIs ≤ 3, tephra volumes ≤ 0.1 km 3 and often eject a significant amount of ash-sized pyroclastic...

Decompression and degassing, repressurization, and regassing during cyclic eruptions at Guagua Pichincha volcano, Ecuador, 1999–2001
In 1999–2001, Guagua Pichincha volcano, Ecuador, produced a series of cyclic explosive and effusive eruptions. Rock samples, including dense blocks...

Historical accounts provide insight on the geological evolution of the 20th century eruptions at Santorini volcano, Greece
The 20th century eruptions of the Santorini volcano in Greece are the most recent activity of the volcano’s long lifespan. While the different...
