Strong eruption and major pyroclastic flow observed at Sinabung volcano, Indonesia

Darwin VAAC reported a high level eruption of Indonesian Sinabung volcano on December 14, 2014. Aviation Color Code was briefly set to Red and later downgraded to Orange as the eruption became less active.

At 02:32 UTC today (09:32 local time) volcanic ash cloud reached an altitude of approximately 6 km, and was extending 18 km to the NW.  Last high level erupting was observed at 03:40 UTC.

A large pyroclastic flow, approximately 4.5 km, was observed coming down the volcano yesterday.

Indonesian Mount Sinabung was sleeping for 400 years before awakening in August 2010. The latest series of eruptions started on September 15, 2013, and continued into 2014.

Two large pyroclastic flows on February 1, 2014, claimed lives of at least 14 people and severely injured 3 others.

Geologic summary

Gunung Sinabung is a Pleistocene-to-Holocene stratovolcano with many lava flows on its flanks. The migration of summit vents along a N-S line gives the summit crater complex an elongated form. The youngest crater of this conical, 2460-m-high andesitic-to-dacitic volcano is at the southern end of the four overlapping summit craters. An unconfirmed eruption was noted in 1881, and solfataric activity was seen at the summit and upper flanks in 1912. No confirmed historical eruptions were recorded prior to explosive eruptions during August-September 2010 that produced ash plumes to 5 km above the summit.
