Massive Eruption at Mount Lewotobi Raises Alert Level to Highest
On Tuesday evening, Mount Lewotobi Laki-Laki, a twin-peaked volcano rising 1,584 meters on Indonesia’s scenic Flores Island, erupted spectacularly, propelling a towering ash column approximately 10,000 meters into the sky.
The eruption occurred at 5:35 pm local time (0935 GMT), prompting local authorities to immediately elevate the volcano’s alert status to the highest level within the four-tier warning system. Observers reported a thick, gray ash plume that markedly darkened the skies above the region.
Safety Precautions and Potential Hazards
So far, no injuries or structural damages have been reported. However, the head of Indonesia’s Geological Agency cautioned residents and visitors against approaching the volcano, urging everyone to maintain a minimum distance of seven kilometers from the crater. This measure aims to prevent exposure to volcanic ash and other potential hazards.
Officials also highlighted the risk of lahar—dangerous mudflows sparked when heavy rains mix with volcanic debris—which could threaten communities near river valleys downstream from the volcano. As a precaution, locals are advised to wear face masks to reduce inhalation of ash particles.
Past Eruptions and Regional Context
This recent activity marks another significant event in Mount Lewotobi’s volcanic history. Notably, in November, multiple eruptions resulted in the tragic deaths of nine people and forced thousands to evacuate. Those disturbances also led to the cancellation of numerous international flights bound for nearby Bali. Fortunately, Tuesday’s eruption has not caused any immediate flight disruptions.
Mount Lewotobi Laki-Laki, meaning "man" in Indonesian, is paired with its taller and less active twin — Perempuan ("woman"), standing at 1,703 meters. This contrasting pair forms a prominent landmark on Flores Island, a popular tourist destination.
Volcanic Activity in Indonesia’s Ring of Fire
Situated along the Pacific “Ring of Fire,” Indonesia is home to hundreds of volcanoes and is prone to frequent seismic and volcanic events. The region’s dynamic geology demands constant vigilance from authorities and residents alike to safeguard against sudden eruptions.
For now, monitoring efforts are ongoing as experts assess Mount Lewotobi’s behavior and potential further activity. Safety protocols remain in place to keep the local population and tourists out of harm's way.
