The geochemical evolution of Montserrat provides an important background to understanding the current activity of this island arc volcano. Here we present major and trace element, and U-, Thand O-isotope data for rocks generated in the last 300 kyr t

Compositions of matrix glasses from the current eruption of Soufriere Hills Volcano indicate that decompression-driven crystallization results in 20-70 wt % groundmass crystallization during eruption and variable degassing. Variations in crystallinit

Eyewitness and survivor accounts allow reconstruction of the sequence of events on 25 June 1997, when a sustained partial collapse of the lava dome occurred leading to the death of 19 people. An unsteady pyroclastic flow was generated with three dist

Pyroclastic flows were formed at Soufriere Hills Volcano by lava-dome collapse and by fountain collapse associated with Vulcanian explosions. Major episodes of dome collapse, lasting tens of minutes to a few hours, followed escalating patterns of pro

The Eruption of Soufrière Hills Volcano, Montserrat, from 1995 to 1999
Dome growth at Soufriere Hills Volcano halted in early March 1998. After dome growth ceased, seismicity reduced significantly, but activity related to dome disintegration and degassing of magma at depth continued. A sustained episode of pyroclastic f

The Eruption of Soufrière Hills Volcano, Montserrat, from 1995 to 1999
In 1997 Soufriere Hills Volcano on Montserrat produced 88 Vulcanian explosions: 13 between 4 and 12 August and 75 between 22 September and 21 October. Each episode was preceded by a large dome collapse that decompressed the conduit and led to the con

40 Ar/ 39 Ar dating has facilitated a substantial reinterpretation of the volcanic evolution of Montserrat. Three volcanic centres with non-overlapping volcanic activity are identified: Silver Hills (c. 2600 to c. 1200 ka); Centre Hills (at least c.

On 17 September 1996 the Soufriere Hills Volcano started a 9 hour period of dome collapse involving 11.7 × 106 m³ (DRE) of lava. After 2.5 hours of quiescence a sustained explosive eruption began. Estimated eruption parameters are: plume height at

From November 1995 to December 1997 a total volume of 246 × 106 (DRE) m³ of andesite magma erupted, partitioned into 93 × 106 m³ of the dome, 125 × 106 m³ of pyroclastic flow deposits and 28 × 106 m³ of explosive ejecta. In the first 11 weeks
