The lava is typical of many Caribbean volcanoes and is known as andesite. Eruption 1992 - Investigation into revived offshore finance industry results in closure of most offshore banks. By late-1996, as magma effusion rates escalated, most seismic events were originating within a volume about 2 km diameter which extended up to the surface from only about 3 km depth - the diminution of shear failure earthquakes suggests the pathway for magma discharge had become effectively unconstricted. Montserrat is a small volcanicisland and is part of the Antilles Islands, at its largest is no more than 12km by 8km. )$162.7 million (2009 est.
