Vulcanian eruption column from Sinabung volcano this morning (@sitepu_yolanda)The activity of the volcano continues to increase. More vulcanian-type explosions have occurred over the past days. Since yesterday evening alone, at least 8 explosions have been registered, the biggest one being probably one this morning that produced an ash plume rising to 25,000 ft (7.5 km) and drifting 60 nautical miles to the NW.
The frequent eruptions have been causing severe ash fall in villages nearby where lapilli of up to 0.5-1 cm in size have fallen. In Medan city 50 km to the NE, ash fall caused disruptions of traffic as visibility was reduced to 20 meters.
The aviation color code (red) and alert status (4 out of 1-4) of the volcano are now on their highest levels. The exclusion zone was extended from 3 to 5 km, which implies that about 10,000 additional people should be evacuated.
