dc.description.abstract |
We estimate that about 1 km(3) of andesitic lava has been produced at Soufriere Hills Volcano, Montserrat from 1995 to 2009. There were three major episodes of extrusion, each lasting about 2 to 3.5 years and producing about 280 to 340 M m(3) of lava, and one minor episode. Our estimates account for the dense rock equivalent volumetric contributions from the core and talus components of the lava dome, pyroclastic flow deposits and air-fall deposits. By 2005 at least two thirds of the erupted mass has already entered the sea. The average lava flux across the major extrusion episodes has been 3-5 m(3)s(-1), with short-period (10-15 days) pulses up to 10-20 m(3)s(-1). The first and third episodes of extrusion show similar flux histories suggesting similar behaviour of the system ten years apart. Waning flux towards the end of each episode may be caused by declining overpressure in the magma reservoir. Citation: Wadge, G., R. Herd, G. Ryan, E. S. Calder, and J.-C.
