Indonesia’s rumbling Mount Lewotobi Laki-Laki erupted again on Monday, sending a column of volcanic materials as high as 18km (11 miles) into the sky and depositing ash on villages.

Indonesia’s Geology Agency said in a statement that it recorded the volcano unleashing an avalanche of searing gas clouds down its slopes during the eruption. There were no immediate reports of casualties.

The column of hot clouds that rose into the sky was the volcano’s highest since the major eruption in November 2024 that killed nine people and injured dozens, said Muhammad Wafid, the Geology Agency chief. It also erupted in March.

“An eruption of that size certainly carries a higher potential for danger, including its impact on aviation,” Wafid said from Switzerland, where he was attending a seminar. “We shall re-evaluate to enlarge its danger zone that must be cleared of villagers and tourist activities.”

The volcano monitoring agency had increased the alert status for Mount Lewotobi Laki to the highest level after an eruption on June 18, and more than doubled the exclusion zone to a 7km (4.3-mile) radius since then as eruptions became more frequent.

By Monday afternoon, at least 24 flights serving between Bali and Australia, Singapore and South Korea were cancelled, and many others delayed, while flights on four domestic routes were cancelled, said Ahmad Syaugi Shahab, spokesperson for Bali’s Ngurah Rai international airport. Domestic flights from Bali to Labuan Bajo were also cancelled.
