Pyroclastic Flows on Mount Semeru.

14 FEBRUARY 2016. The Center for Volcanology and Geological Hazard Mitigation (PVMBG) in Bandung reports Pyroclastic Flows from Mount Semeru, on Saturday morning, February 13, 2016.
PVMBG head, Edi Prasojo, said it appears at this stage to be Pyroclastic Flows from Mount Semeru, due to the formation of a lava dome in the crater.



« Provisional estimates for the formation of a hot cloud glowing dome November 2015. Because after November 2015, all the parameters down (tremor or the number of avalanches), » said Edi via short message on Saturday afternoon, February 13, 2016. The indication is not that continuous Pyroclastic Flows will occur. After the incandescent lava flows on Saturday morning, there were no subsequent Pyroclastic Flows.
Nevertheless, Semeru Volcano Observation Post Mount Sawur, Sumberwuluh Village, District Candipuro, Lumajang will continue to conduct continuous observations in 24 hours.
As reported earlier, reported from Semeru Volcano Observation Post Pyroclastic Flows have occurred at 06:05 am as far as approximately 4-5 kilometers from the peak Semeru and headed toward the South and Southeast sector.

« On Saturday morning, around 06:00, the crater of the Semeru has emitted volcanic material that came out suddenly, may be lava. This produced a dark gray smoke that went in the same direction as the flow « said Lasmono, a villager in Oro-oro Ombo.


The level of activity of Mount Semeru is still level II or alert since 2012 with safe distance beyond 4 kilometers to the South and Southeast sector. Distance to the nearest village to the South and Southeast wine sector about 9 kilometers. Alleged while clouds of hot avalanches were caused by the activity of lava dome growth in November 2015 around the peak.
« Tongue or a lava dome last November 2015 became broken or unstable in February 2016 », Edi said today. PVMBG will evaluate whether the source of hot clouds of material is from the known dome of November 2015 or if a new supply source has occurred. From these evaluations, it will determine the status of the activity at Mount Semeru.
