Jakarta. Mount Sinabung in North Sumatra erupted again on Wednesday (27/12), spewing volcanic ash up to 4,600 meters into the sky, the National Disaster Mitigation Agency, or BNPB, said.
No casualties have been reported.
The volcano alert has been on the highest level since June 2015.
A rain of volcanic ash fell on several villages on the eastern slope of the mountain, BNPB spokesman Sutopo Nugroho said in a statement.
"Thank God, no fatalities have been reported," Sutopo told the Jakarta Globe over the phone.
An evacuation zone around the volcano has been expanded to a seven-kilometer radius.
"Residents who live near the rivers upstream from Sinabung must be watchful for lava," Sutopo said, warning that riverbeds may unable to accommodate the flow.
