Indonesia which is located on the Philippine plate. I believe the
last eruption occurred in 1806. Please send current information as well

Ken for Michael
Dear Michael (via Ken),
The volcanoes of Indonesia result from the subduction of the oceanic part
of the Australian plate beneath the Asian plate. The Philippine plate is
to the north and is not associated with the volcanoes in Indonesia. The
curving line of volcanoes that makes up the islands of Indonesia is
called the Sunda arc. The first recorded eruption was Krakatau in the
3rd century A.D. Indonesia has 76 active volcanoes, the largest number
of any volcanic region. Explosive eruptions are relatively common.
Between 1976 and 1994 there were 26 eruption that required the evacuation
of people. Fatalities have been avoided in all but a few eruptions. The
Volcanological Society of Indonesia has 64 volcano observatories and
continuously monitors 59 volcanoes. The Global Volcanism Network
reported eruptions at Semeru and
Anak Krakatau
in June of 1995.
