JAKARTA, Indonesia — Major eruptions at five volcanoes in Indonesia have darkened skies with ash over a large swath of the archipelagic nation and three airports have closed.

Government volcanologist Surono said Mount Raung on Java island erupted again Wednesday, blasting ash and debris up to 2,000 metres (6,560 feet) into the air after rumbling for several weeks.

Eruptions of Gamalama and Dukono mountains on the Moluccas islands chain and the Sinabung volcano on Sumatra island have darkened skies and forced the evacuation of more than 10,000 people. Mount Karangetang on Siau island also erupted.

Transport Ministry spokesman Julius Adravida Barata said Jember and Banyuwangi airports closed late Tuesday and Bali’s international airport was closed for several hours on Wednesday, disrupting flights.

Indonesia has 130 active volcanoes.
