Evacuations are underway after a strong swarm of earthquakes including a magnitude 4.5 quake led to the alert level being raised to orange at Indonesia's Bur ni Telong volcano. There is now a chance that a phreatic eruption might occur, which while low, is sufficient enough to warrant the 4 kilometer exclusion zone. Bur ni Telong is an andesitic lava dome which has not erupted in nearly a century (last eruption was in 1937).
