Mount Sinabung is a 2 460 meters high Pleistocene-to-Holocene stratovolcano located in Tanah Karo Regency, North Sumatra Province of Indonesia. The migration of summit vents along N-S trending line has given an elongated form of its summit. The youngest crater of this conical andecitic to dacitic stratovolcano is at southern end of four overlapping craters. Solfataric activity WAS seen on its summit and upper flanks of Sinabung in 1912. there is no historical record of Sinabung eruption before today, as volcanological data from Indonesian Volcanism Bureau had been classified this volcano in Type B volcano, meaning that this volcano is never erupted before 1600 AD and features volcanic activity. Because it was included as a Type B volcano, (until today) there is no volcanism observatory at this mountain. All volcanic activity is observed from Medan. Now this volcano is classified into Type A, meaning that there is a known historical eruption of the volcano after 1600 AD.
Surono, the chairman of Geologic Hazard Mitigation and Volcanism Center was swear, "if Sinabung Volcano is gonna erupt, i have to put my position as a chairman". Now, the Sinabung volcano is erupt and i beg your swear! :-)
Aids has came to the disaster-affected region. The aids are mostly came in form of maskings, 75 government officers, foods, and other kind of logistics. I predicted that the ash from Sinabung will interfere some flight schedules from International Airport of Polonia 3 days from now, the cause is the ash will be directed North East. (based on GFS model).
