Eruptions at three volcanoes in Indonesia have darkened skies in parts of the archipelago and disrupted some flights this week.
Sinabung volcano on Sumatra Island and Mount Gamalama in the Moluccas chain of islands have both erupted in the past couple of days, along with Mount Rinjani on Lombok Island near Bali.
No one has been injured, but flights at two airports have been disrupted.
Sultan Babullah airport in Ternate, the capital of North Maluku province, was closed Wednesday and Lombok's international airport was closed for several hours on Tuesday.
The three mountains are among about 130 active volcanoes in Indonesia.
