Agung (Indonesia) - Report for 6 June-12 June 2018

PVMBG reported that during 1 May-7 June activity at Agung remained at a relatively high level.
Emissions were mostly water vapor, occasionally with ash.
In general, tiltmeter and GPS showed long-term deflation since December 2017, though inflation began to be detected the second week of May; deformation analysis indicated that magma continued to accumulate about 3-4 km below the crater.
Low- and high-frequency earthquakes also suggested rising magma.
Sulfur dioxide flux was 190-203 tons/day, and thermal anomalies in the crater were identified in satellite data.
The erupted volume of lava was estimated to be 23 million cubic meters, equivalent to about a third of the total crater volume.
At 2214 on 10 June an event generated an ash plume that drifted W at an unspecified altitude.
The Alert Level remained at 3 (on a scale of 1-4) and the exclusion zone was stable at a 4-km radius.
