LEMBATA, Indonesia (AP) — Mount Lewotobi Laki Laki volcano in south-central Indonesia erupted on Tuesday, spewing towering columns of hot ash into the air. Authorities raised the eruption alert to the highest level and expanded the danger zone to about 5 miles from the crater.

Indonesia’s Geology Agency said in a statement it recorded the volcano unleashing 10,000 meters (about 32,800 feet) of thick grey clouds on Tuesday afternoon, following significant volcanic activities, including 50 in two hours, rather than the usual daily 8 to 10 activities.
