Slamet volcano (Central Java, Indonesia) - Smithsonian / USGS Weekly Volcanic Activity Report for 7 October-13 October 2020 (Continuing Activity)

PVMBG reported that during 1 September-9 October white emissions rose as high as 100 m above Slamet's summit. During the previous two weeks seismicity significantly decreased, specifically tremor and the signals indicating emissions. The magnitude of earthquakes returned to baseline levels.
Tiltmeter data from an instrument on the upper E flank indicated inflation in the upper part of the edifice, though data from an instrument located N of the volcano indicated no overall deformation. On 8 October the Alert Level was lowered to 1 (on a scale of 1-4) and the public was warned to stay outside a radius of 1 km.

PVMBG has raised the alert level to 2 due to a two month sustained increase in seismicity (over 50,000 earthquakes!) and, in the last few weeks, inflation, gas emissions (with steam plumes rising 300m above the crater), rising hot spring temperatures and emergence of seismic tremor. All of this indicates that magma is rising under the mountain. An exclusion zone of 2km is in place, as the likelihood of a new eruption is elevated. ... Read all

PVMBG reported that seismicity at Slamet significantly increased beginning in June, with 51,511 signals indicating emissions and 22 tectonic earthquakes recorded through 8 August. White plumes with variable density rose as high as 300 m above the crater rim.Tremor began to be recorded at the end of July with gradually increasing amplitude. In addition, notable inflation was detected at the end of July and long-term temperatures of hot springs showed an upward trend. ... Read all
