Montserrat Island
Montserrat is a volcanic island in the Caribbean. On the southern end of the
island is the Soufriere Hills volcano. The volcano, which first erupted about
100,000 years ago, has been dormant for centuries. The volcano took the
islanders by surprise when it began to erupt again in 1995. Since then life on
the island has changed greatly. Montserrat island is located in a 50 million
year old subduction zone. This is an area where one of the earth’s oceanic
plates is forced beneath a more buoyant plate. Fluids rich in water and
dissolved minerals are taken out of the crust that is being driven into the
earth’s mantle by the extreme temperatures and pressure. When the fluids rise
they cause the overlying mantle to melt and form magma. The magma erupts along
the subduction zone and eventually builds up on itself and forms volcanic
islands. * http://www.geo.mtu.edu/volcanoes/west.indies/soufriere/govt/images/forty.jpg
The volcano began erupting again on July 18, 1995 after remaining silent for
almost four hundred years. The volcano has erupted numerous times since then.
The southern part of the island has been evacuated three times. There are about
3,200 people living on the island today. Of the 8,00 that fled most plan to
return to the island once the volcano settles down. The problem is that no one
knows when that will be. It could be a long time before the people return to the
island. * http://www.nationalgeographic.com/features/98/volcanoes/images/1ml-back1.jpg
