An Indonesian volcano, Mount Lewotobi Laki-Laki, erupted on Monday morning, shooting a massive ash cloud 18 kilometres into the sky. The eruption on the island of Flores happened at 11:05 A.M. local time.

So far, no damage or casualties have been reported, according to Hindustan Times.

This is the third time the volcano has erupted in 2025, HT reported. Following an eruption in June, the volcano’s alert status was raised to the highest level, and a 7-kilometre safety zone was established around it. That eruption also caused volcanic ash to rain down on nearby villages, leading to evacuations.

Authorities have warned residents about the possibility of lahar floods, which are fast-moving flows of mud and volcanic debris.

Mount Lewotobi Laki-Laki is a twin volcano, paired with another peak named Perempuan. Indonesia, a hotspot for volcanoes, is situated on the Pacific "Ring of Fire” and reportedly has over 100 active volcanoes.
