FLORES, INDONESIA: Mount Lewotobi Laki-Laki, a volcano located on the Indonesian island of Flores, erupted on Monday, sending a massive ash plume 18 kilometres (11 miles) into the atmosphere, according to the country’s volcanology agency. Authorities reported no immediate casualties or property damage.
The eruption occurred at approximately 11:05 a.m. local time (0305 GMT), with officials describing the ash column as “colossal” and warning nearby communities of potential lahar — fast-moving flows of volcanic debris and mud — especially during heavy rainfall.
“The activity level at the volcano is very high, marked by explosive eruptions and continuous tremors,” said Muhammad Wafid, head of Indonesia’s geological agency. He urged residents to stay at least six kilometres (3.7 miles) from the volcano and to wear face masks to guard against ash inhalation.
Mount Lewotobi Laki-Laki, which stands 1,584 metres tall, has become increasingly volatile in recent months. A previous eruption in June led to the cancellation of dozens of flights to and from Bali, and earlier eruptions in November 2023 claimed nine lives, forced thousands to evacuate, and disrupted international air travel.
Despite the dramatic ash plume on Monday, operations at Bali’s Ngurah Rai International Airport remained unaffected, according to an InJourney Airports customer service agent. Indonesia’s transport ministry and the airport operator had not commented as of press time.
The volcano is part of a twin-peak system, with its companion summit, Mount Lewotobi Perempuan — meaning “woman” in Indonesian — known for its relatively calmer activity.
Indonesia, situated along the seismically active Pacific “Ring of Fire,” is home to more than 120 active volcanoes and experiences frequent geological disturbances, including earthquakes and volcanic eruptions.
Authorities continue to monitor Mount Lewotobi Laki-Laki closely, with ongoing advisories issued for aviation and nearby populations.
