Indonesia’s Mount Lewotobi Laki-Laki erupted on June 18, 2025, sending an enormous column of ash over 11 kilometers into the sky. Located in East Nusa Tenggara province, the volcano showed intense seismic activity before the blast. Indonesia’s geological agency immediately raised the alert level to the maximum, warning of further eruptions.
This marks one of the most significant volcanic events in Indonesia this year. The agency advised residents and visitors to stay at least 7 kilometers away from the crater, citing ongoing tremors and ash fallout. Several villages near the volcano underwent emergency evacuations.
Mount Lewotobi, consisting of two volcanic cones -Lewotobi Laki-Laki (male) and Lewotobi Perempuan (female), has a long history of eruptions. Located on the island of Flores in eastern Indonesia, the volcano last erupted in November 2023, forcing thousands to evacuate. Indonesia sits on the Pacific “Ring of Fire,” making it one of the most volcanically active regions in the world. With over 120 active volcanoes, the country faces regular seismic threats that often disrupt daily life and travel. Authorities monitor the region continuously, but volcanic ash clouds, like the one from Lewotobi, can quickly ground flights and endanger nearby communities.
The eruption had a widespread impact on international air travel. Authorities at Ngurah Rai International Airport in Bali confirmed that at least 32 flights were cancelled or diverted due to volcanic ash affecting visibility and air safety.
Flights between India and Bali, including Air India flight AI2145 from Delhi, had to turn back mid-air. The airline safely returned to Delhi and disembarked all passengers. Similarly, Singapore Airlines, Scoot, Jetstar, and Virgin Australia suspended routes connecting Bali with Singapore, Brisbane, and Melbourne. Air New Zealand also cancelled services from Auckland, and Malaysia-based carriers paused departures to Denpasar.
Indonesia’s disaster agency relocated hundreds of residents from high-risk zones. The government also temporarily shut down Fransiskus Xaverius Seda airport in Maumere as a safety precaution.
Travelers have been advised to monitor airline alerts and refrain from visiting areas within the exclusion zone. Airlines continue to assess the situation and will resume services once conditions improve.
Indonesia, situated on the Pacific Ring of Fire, experiences frequent volcanic eruptions. This eruption serves as another reminder of the region’s unpredictable seismic activity and its growing impact on tourism and transportation
