Watch: Moment volcano erupts, spews 6.8 miles-high ash cloud in Indonesia
Indonesia’s Mount Lewotobi Laki-Laki volcano erupted on Monday, sending ash skyward and prompting evacuations.
Indonesia’s Mount Lewotobi Laki-Laki volcano erupted on Monday, sending a fiery plume of ash 11 kilometres (6.8 miles) high into the sky, per Reuters. The disaster has forced hundreds of residents from surrounding villages to evacuate. The eruption, which occurred on Flores Island in East Nusa Tenggara province, prompted authorities to issue an urgent safety advisory, restricting activity within 6 kilometres of the crater.

Authorities issue a high alert after volcanic eruption
Indonesia’s Centre for Volcanology and Geological Hazard Mitigation (PVMBG) confirmed the eruption and raised the alert level.
“The public and tourists are urged not to carry out activities within a radius of 6 km from the eruption centre. Remain calm and follow directions from the local government,” the agency said in an official statement.
The volcanic ash cloud triggered emergency protocols across the region, with many residents seeking shelter and wearing masks to protect against fine particulate inhalation.
Risk of lava floods adds to fears
Beyond the immediate dangers of ash and falling debris, officials warned of another serious threat-lava flooding. If heavy rainfall combines with volcanic material, lahars could form and flow into low-lying areas.
Communities near watersheds upstream of Lewotobi, including Dulipali, Nobo, Hokeng Jaya, and Nurabelen, have been asked to remain alert.
“In addition, communities around disaster-prone areas should be aware of the potential for lava flooding in the event of heavy rain,” the PVMBG stated.
Monitoring continues, flights on watch
Emergency crews remain stationed near the volcano as monitoring continues. Lewotobi’s eruption has also prompted aviation alerts, though no major flight disruptions have been reported so far.
The twin-peaked volcano last recorded notable activity late last year, raising concerns about its increasingly volatile behaviour. Residents impacted by ashfall have been advised to use face coverings and avoid outdoor exposure for extended periods.
