Lewotobi Laki-Laki Volcano Erupts Again: Indonesia on High Alert as Ash Plumes Soar
October 15, 2025
Despite the explosive activity, there have been no reports of injuries or fatalities, and previous eruptions have caused no structural damage.
Heavy rains in the region have raised concerns about possible volcanic mudslides, adding to the hazards associated with the ongoing eruptions.
The volcano is part of the Pacific Ring of Fire, a zone known for its frequent seismic and volcanic activity.
Indonesia's volcanic activity is a reminder of its position on the Ring of Fire, which contributes to its high number of active volcanoes and frequent eruptions.
The Lewotobi Laki-Laki volcano on Indonesia's Flores Island erupted again, producing ash plumes up to ten kilometers high and prompting the highest alert level from authorities.
Indonesia, part of the Pacific Ring of Fire with over 120 active volcanoes, frequently experiences seismic activity and eruptions, including recent events that caused regional flight cancellations.
This eruption marks the second within 24 hours, with the previous one on October 14, 2025, also generating significant ash clouds that disrupted air travel.
The volcano's recent activity is part of a pattern of ongoing unrest since July, with seismic signs such as shallow tremors and upward-moving magma indicating continued volatility.
The eruption was accompanied by an explosion around 01:35 local time, lasting over four minutes, and has led to the temporary closure of Frans Xavier Seda Airport in Maumere.
Authorities have issued the highest alert level, evacuated nearby villages, and established a six-kilometer exclusion zone to prevent injuries and protect agricultural areas from ash fall.
The eruption has created a substantial ash column, posing risks including ash fall, air travel disruptions, and potential further volcanic activity.
The volcano remains highly active with ongoing seismic activity, including shallow tremors and rising magma, indicating continued unrest.
Media outlets such as the Straits Times have documented the eruptions with videos, highlighting the scale of the volcanic activity.
