Indonesian Volcano Erupts, Prompts Evacuation and Flight Warnings
Mount Lewotobi Laki-Laki, a volcano on the Indonesian island of Flores, has entered a new phase of heightened activity. On August 1, 2025, the volcano erupted twice between the evening and early morning. The second eruption was particularly powerful, sending a column of volcanic ash up to 18 kilometers (approximately 11 miles) into the sky. The eruption was accompanied by rumbling, loud booms, glowing lava, and volcanic lightning.
The volcano, part of the Lewotobi twin volcano complex, has been at its highest alert level, Level IV, due to continuous activity since late 2023. The recent eruptions on August 1st and 2nd followed a period of decreased activity and a buildup of pressure.
Authorities have established an exclusion zone around the crater and have advised residents and visitors to stay away. They have also warned of the potential for lahars, which are dangerous mudflows created when volcanic debris mixes with heavy rainfall. Volcanic ash has caused flight delays and cancellations at nearby airports, and residents have been urged to wear masks to protect against the health hazards of the ash.
