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.

Magmas and magma chamber evolution, Troodos ophiolite, Cyprus [PDF]

Geology, 1987
The Troodos ophiolite traditionally has been considered to have formed by constructive processes at an oceanic spreading center. New information on the phase layering and cryptic variation in gabbros and ultramafic cumulates overlying tectonized harzburgites, however, does not support the existence of a large, steady-state, frequently replenished ...

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) Eruption, remelting can occur without a significant increase of the magma temperature, but simply ...

Magnetotelluric evidence for the deep causes of different eruptive styles of Changbaishan Tianchi and Longgang volcanoes [PDF]

Scientific Reports
Longgang 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.
