stratovolcano

Soufrière St. Vincent volcano is located on St Vincent Island, Caribbean. The Yellow Tephra Formation was deposited during explosive eruptions 4300 years ago.

2005 Sulphurous Odours
In February 2005 sulphurous odours and haze was reported on the island of St. Vincent and as far as the Grenadines 50-75 km south. This resulted from changes in wind patterns rather than increased gas output.

1979 Eruption
Explosions and lava extrusion accompanied the last eruption of the volcano in 1979.
Powerful explosions from Soufrière in April 1979 produced large ash clouds and pyroclastic avalanches, forcing the evacuation of more than 17,000 persons from the northern end of St. Vincent. The largest hot pyroclastic avalanche flowed down the Larikai River valley 14 April 1979 and continued several kilometers out to sea. A lava dome grew in the crater until late October 1979.
