On 29 August 2010, the volcano experienced a minor eruption after several days of rumbling. Ash spewed into the atmosphere up to 1.5 kilometres (0.93 mi) and lava was seen overflowing the crater. The volcano had been inactive for centuries with the most recent eruption occurring in 1600.
Mount Sinabung is classified as category “B”, which means it is not necessary for it to be monitored intensively. Other volcanoes, in category “A”, must be monitored frequently, the head of the National Volcanology Agency, named only as Surono, told Xinhua over phone from the province.
Authority response
Indonesian authorities were reported to have evacuated around 18,000 people from the region on and around the volcano. The government issued the highest-level warning for the area, which was expected to remain in force for around a week, since scientists were unfamiliar with the characteristics of the volcano, due to it having been dormant for so long. The government has also set up kitchens for refugees to have access to food, and have handed out 7,000 masks. Over 10,000 people have been internally evacuated after the eruption, Secretary of the provincial administration Edy Sofyan told Xinhua by phone. Spokesman of National Disaster Management Agency Priyadi Kardono said the eruption has not been predicted much earlier like other volcanoes and authorities must conduct a quick preparation for emergency work as mount Sinabung’s seismic activity has been monitored intensively only since Friday after it showed an increase in activity.
Effects
The nearest towns to the volcano are Kabanjahe and Berastagi; there were no disruptions reported to air services at the regional airport, Medan’s Polonia. One person is reported dead from respiratory problems while fleeing his home.
