Indonesia halted operations at its main international airport outside Jakarta on Sunday after ash spewed from the Anak Krakatoa volcano more than 150 kilometres away, impacting thousands of passengers.
Mount Anak Krakatoa erupted on Saturday, producing a fountain of lava and booming sounds that could be heard up to 700 kilometres (435 miles) away, the geology agency said in a statement.
Two new eruptions were recorded on Sunday, the volcanology agency warned.
