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.

The eruption of Mount Lewotobi Laki-Laki in Indonesia has prompted the highest volcanic alert and travel advisories in East Nusa Tenggara.
