Time scales and temperatures of crystal storage in magma reservoirs: implications for magma reservoir dynamics. [PDF]
The thermal and therefore physical state of magma bodies within the crust controls the processes and time scales required to mobilize magmas before eruptions, which in turn are critical to hazard assessment. Crystal records can be used to reconstruct magma reservoir histories, and the resulting time and length scales are converging with ...

Seismic Detection of a Magma Reservoir beneath Turtle Island of Taiwan by S-Wave Shadows and Reflections [PDF]
Although surface geology, eruption information and clustering seismicity all suggest Turtle Island (Kueishantao) of northern Taiwan is an active volcano, there was no direct evidence to conclude that magma reservoirs exist beneath it.

Growth and thermal maturation of the Toba magma reservoir. [PDF]
Significance Understanding the thermal state of magma reservoirs before supereruptions is crucial for interpreting the processes leading to such catastrophic events. Here, we show that the two supereruptions of Toba were preceded and followed by protracted magma influx at relatively constant average volumetric rate over the past 2.2 ...

Magma convection favors ephemeral melt-rich bodies within mushy reservoirs [PDF]
Magma convection is a mechanism that greatly enhances heat transfer from mobilizable, crystal-poor magma bodies to the surrounding immobile, crystal-rich mush reservoir of Earth’s igneous systems.

Long-period microseismicity reveals cryptic earthquake-triggered fluid activity can facilitate caldera eruptions [PDF]
Spatiotemporal correlations between moderate-to-large earthquakes and volcanic eruptions indicate that earthquake-induced stress changes can trigger eruptions.

Redox and magma recharge controls on excess sulfur build-up at Mount Samalas, 1257 CE [PDF]
The 1257 CE eruption of Mount Samalas (Indonesia) caused the largest stratospheric sulfur injection of the Common Era, as recorded by Greenland and Antarctic ice cores, and led to strong climate perturbations.

Strong seismic reflections indicating possible eruptible magma beneath the Tatun Volcano Group in Taiwan [PDF]
The Tatun Volcano Group (TVG), located at the northern tip of Taiwan, is situated near the Taipei metropolitan area. A future eruption of the TVG could have a significant impact not only on Taipei but also on the global economy, as Taiwan produces over ...

Scenario-based forecast of the evolution of 75 years of unrest at Campi Flegrei caldera (Italy) [PDF]
Campi Flegrei last erupted in 1538 and periods of increased seismicity, gas emission and ground deformation occurred in the 50’s, 70’s 80’s and are ongoing since 2005.

Architecture and dynamics of magma reservoirs [PDF]
This introductory article provides a synopsis of our current understanding of the form and dynamics of magma reservoirs in the crust. This knowledge is based on a range of experimental, observational and theoretical approaches, some of which are multidisclipinary and pioneering.
