Credit: MAGMA Indonesia 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. Thu, 4 Jun 2015, 11:05 PVMBG reported that during 21 April-21 May dense white plumes rose as high as 700 m above Slamet's crater. ...moreSeismicity consisted of emission signals and tremor; RSAM values fluctuated. The Alert Level remained at 2 (on a scale of 1-4). Residents and tourists were warned to not approach the crater within a radius of 2 km. [ less] Mon, 12 Jan 2015, 09:55 PVMBG reported that during 1 November-5 January white plumes rose at most 1.5 km above Slamet's crater.

The mild strombolian activity which had been going on for months at the volcano has become more and more intense since the beginning of September. Some explosions in the past days have been strong enough to eject incandescent material to all over the summit cone of the volcano. ...moreIn its latest report on 11 Sep, VSI mentions that 165 eruptions occurred on that day with ejection heights between 50-1500 m. BNPB, Indonesian's Civil Protection began preparing for a possible evacuation. According to them, 23,699 people are located within a radius of 5 to 6 km from the summit, and the area up to 4 km radius around the volcano has been declared an exclusion zone.

Fri, 5 Sep 2014, 08:51 Strombolian explosions are continuing from the new cone inside the summit crater. Some of them produce small ash plumes spotted on satellite imagery by VAAC Darwin who monitor the (volcanically very busy) region for volcanic ash plumes.
