Coupled subdaily and multiweek cycles during the lava dome erupt of Soufriere Hills Volcano, Montserrat [PDF]
, 2013 Observations of volcanoes extruding andesitic lava to produce lava domes often reveal cyclic behaviour. At Soufriere Hills Volcano, Montserrat, cycles with sub-daily and multi-week periods have been recognised on many occasions.

Magma volume, volatile emissions, and stratospheric aerosols from the 1815 eruption of Tambora [PDF]
, 2004 We suggest that the Tambora 1815 eruption was smaller than previously thought, yielding 30–33 km3 of magma. Valuable insight into the eruption is gained by comparing it to the much smaller 1991 Pinatubo event, which had a similar eruption style and rate.

Stress fields around magma chambers influenced by elastic thermo-mechanical deformation: implications for forecasting chamber failure [PDF]
, 2021 Defining the conditions that lead to the rupture of a magma chamber is essential to forecast eruptions. So far, models simulating magma chamber dynamics have neglected the effects of elastic thermal expansion in the host rocks surrounding a new injection

The Boycott effect in magma chambers [PDF]
Geophysical Research Letters, 2004 We investigate the plausibility of the stratified Boycott effect as a source of layering in magma chambers. Crystal settling within the magma chamber will generate buoyant fluid near the sloping sidewalls whose vertical ascent may be limited by the ambient stratification associated with vertical gradients in SiO2.

Three-dimensional thermal sensitivity analysis of cooling of a magma chamber in the Los Azufres geothermal field, Michoacán, Mexico [PDF]
, 2013 "We present three-dimensional simulation of cooling of 63 models of a magma chamber in the Los Azufres geothermal field by varying the top of the chamber depth between 5 and 9 km (centroid from about 7 to 13 km) and its volume between 300 and 600 km3.

Seismic Imaging of a Magma Chamber and Melt Recharge of the Dormant Datong Volcanoes
Earth and Space Science, 2021 The Datong volcanoes erupted episodically from ca. 0.74 to ca 0.10 Ma with the last eruption at ca. 100 ka, and ever since has remained dormant. It remains elusive whether the Datong volcanoes are being recharged and would become active again in the near
