Mount Lewotobi Laki-Laki on Flores Island, eastern Indonesia, erupted several times on June 5, creating large piles of ash and forcing a local airport in Maumere town to close.
According to the Indonesian national volcanic agency, the latest eruption occurred at 11:15 am, pushing volcanic material to an altitude of about 2.5 km above the crater.
The closure of the Maumere airport has affected 5 domestic flights.
Lewotobi Laki-Laki is currently at the 2nd highest alert level in Indonesia's volcanic activity warning system. Authorities have established a no-fly zone within a radius of 5 km around the crater to ensure safety.
Functional agencies also recommend that people raise their vigilance against the risk of mud and lava floods, also known as lahar, if heavy rain appears in the area.
Mount Lewotobi Laki-Laki is 1.584m high. In Indonesian, "Laki-Laki" means "man". This mountain is located next to a 1.703m high twin volcano called Perempuan, which means "woman".
This is not the first time Lewotobi Laki-Laki's activities have affected air traffic. In July 2025, this volcano crowned a giant column of ash up to 18km high, causing the international airport on the resort island of Bali to cancel 24 flights.
Indonesia is one of the countries with the strongest seismic and volcanic activity in the world due to its location on the Pacific "Fire Belt", an area that regularly records earthquakes and volcanic eruptions.
