Active volcanoes / Aktive vulkaner:
Lokon-Empung, Indonesia   



Eruption from the Tompaluan crater May 13th, 1987. Lokon to the left..



The twin volcanoes Lokon and Empung, rising about 800 m above the plain of Tondano, are among the most active
volcanoes of Sulawesi. Lokon, the higher of the two peaks ( whose summits are only 2.2 km apart), has a flat, craterless
top. The morphologically younger Empung volcano has a 400-m-wide, 150-m-deep crater that erupted last in the 18th
century, but all subsequent eruptions have originated from Tompaluan, a 150 x 250 m wide double crater situated in the
saddle between the two peaks. Historical eruptions have primarily produced small-to-moderate ash plumes that have
occasionally damaged croplands and houses, but lava-dome growth and pyroclastic flows have also occurred.

Mt. Lokon near Tomohon city, erupted three times on Tuesday morning, according to the Volcanology and Geology Disaster Mitigation Center (PVMBG). The first eruption occurred at 3:07 a.m. local time (2:07 a.m. Jakarta time),
followed shortly by two other eruptions.

The volcano's activity has been increasing since Monday, when there were 5 explosions, and ash rose 250 m into the air.
The volcano's activity accelerated on Tuesday when 23 deep volcanic tremors, 40 shallow volcanic tremors, four blows
and three eruptions were recorded. Alert-level continues on ORANGE, no 3 of 4, with an exclusion zone of
2.5 kilometers from the volcano.

The volcano erupted on July 15, forcing more than 5,000 people from three villages to evacuate for two weeks
