Mount Lewotobi Laki‑laki erupted on Tuesday (June 17), sending a towering ash plume up to 11 km into the sky, which grounded dozens of flights to and from Bali. Located in East Nusa Tenggara Province, Indonesia, the volcano is one half of a twin peak known locally as “Laki-laki” (male) and “Perempuan” (female).

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.
