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.

There were no immediate reports of injury after Mount Lewotobi Laki-laki ejected a plume of smoke and ashes on Tuesday night. An eruption there killed 10 people last year.
