Caldera collapse thresholds correlate with magma chamber dimensions [PDF]
Scientific Reports, 2023 Explosive caldera-forming eruptions eject voluminous magma during the gravitational collapse of the roof of the magma chamber. Caldera collapse is known to occur by rapid decompression of a magma chamber at shallow depth, however, the thresholds for ...

Dense seismic arrays deny a massive magma chamber beneath the Taipei metropolis, Taiwan [PDF]
Scientific Reports, 2021 Several recent studies suggest that the Tatun Volcano Group (TVG) in the Taipei metropolis of Taiwan is still active with a mappable magma chamber beneath it.

Forecasting magma-chamber rupture at Santorini volcano, Greece. [PDF]
Sci Rep, 2015 How much magma needs to be added to a shallow magma chamber to cause rupture, dyke injection, and a potential eruption? Models that yield reliable answers to this question are needed in order to facilitate eruption forecasting.

Collapse-driven large eruptions [PDF]
Geology, 2015 For a typical poroelastic shallow crustal magma chamber, about 0.1% of the mafic magma and about 4% of the felsic magma are erupted and/or injected during magma-chamber rupture.

Volcanic eruptions from ghost magma chambers [PDF]
Geophysical Research Letters, 2008 Recent studies have proposed that magma reservoirs crystallized to a virtually rigid crystal-mush can be partially remelted by diffusion of hot fluids. We show that for a crystal mush with the composition of a K-trachyte from the Campanian Ignimbrite (CI)

Magnetotelluric evidence for the deep causes of different eruptive styles of Changbaishan Tianchi and Longgang volcanoes [PDF]
Scientific ReportsLonggang Volcano (LGV) and Changbaishan Tianchi Volcano (CTV) share a common magmatic source at mantle depths. However, the two volcanoes have produced completely different types of eruptions.
