The danger zone around Mount Sinabung has been extended after it spewed gas and lava farther than expected.
The volcano was still spitting clouds of gas and lava as high as 13,000 feet in several eruptions on Sunday.
Officials have moved more than 6,300 families to 32 disaster centers outside of the danger zone.
Homes in the villages of Jewara and Pintu Besi, about four miles from the crater, were covered in volcanic dust.
Indonesia's National Disaster Mitigation Agency (BNPB) spokesman Sutopo Purwo Nugroho said yesterday the danger zone southeast of the volcano has been extended from three to four miles from the crater.
The BNPB stated that the volcano had erupted at least 77 times in a 24-hour time frame.
Another BNPB official told The Wall Street Journal that a further increase of the existing evacuation zone would displace nearly 60,000 local residents.
Sinabung is one of about 130 active volcanoes in Indonesia in danger of erupting because of fault lines encircling the Pacific Basin.
Residents are using any means necessary to avoid inhaling the volcanic ash.
Everything within the evacuation zone was coated in the dust.
The evacuation order hasn't prevented throngs of onlookers from taking in the awesome spectacle, however.
