Tuesday, Dec 01, 2015
Last week, PVMBG raised the alert level of Indonesia's northernmost known active volcano a notch, as small signs of new unrest had been detected recently: mostly, this is an increase in shallow seismic activity since the summer and more pronounced since the middle of November. ... [more]

The massive Gunung Awu stratovolcano occupies the northern end of Great Sangihe Island, the largest of the Sangihe arc. Deep valleys that form passageways for lahars dissect the flanks of the 1320-m-high volcano, which was constructed within a 4.5-km-wide caldera.

Background:

Awu is one of Indonesia's deadliest volcanoes; powerful explosive eruptions in 1711, 1812, 1856, 1892, and 1966 produced devastating pyroclastic flows and lahars that caused more than 8000 cumulative fatalities during 5 eruptions (in 1711, 1812, 1856, 1892 and 1966).
Awu contained a summit crater lake that was 1 km wide and 172 m deep in 1922, but was largely ejected during the 1966 eruption.

The eruption in 2004 prompted the evacuation of 27,000 people, but the eruption eventually did not escalate into a major event.
