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.
