Mount Slamet has been erupting on and off since days ago, but went to overdrive on Friday, according to him. Authorities warned residents to remain outside a four-kilometer radius of the volcano. The volcano last erupted in 1999.

There were no casualties or damage from the eruptions and residents went about their activities as usual, said Sutopo Purwo Nugroho, a spokesman for the National Disaster Management Agency.
