Lewotobi Volcano

On 12th November 2025, Indonesia’s Mount Lewotobi Laki-laki erupted twice, sending massive plumes of volcanic ash into the sky and prompting authorities to elevate the alert status to its highest level due to rapidly increasing volcanic activity.

Mount Lewotobi Laki-laki, located in East Nusa Tenggara province, erupted early for nearly nine minutes, shooting volcanic ash up to 10 kilometres into the atmosphere as confirmed by the country’s Geological Agency.
A second eruption occurred the same morning at 9:21 a.m., lasting about three minutes and spewing ash columns reaching a height of 8 kilometres, indicating continued instability within the volcano’s magmatic system.
Indonesia’s volcanology agency had already raised the alert status to the highest level late Tuesday after detecting a significant escalation in volcanic activity beginning on Monday, reflecting the growing threat to surrounding communities.
