Around 100,000 people near Bali's Mount Agung have been ordered to evacuate as officials fear a major eruption.
Indonesian authorities have raised the state of alert to its highest level, and expanded the exclusion zone around the rumbling volcano.
The island's airport has now closed, leaving thousands stranded in the tourist hotspot.
Authorities say dark smoke and ash have been billowing up to 3,400m (11,150ft) above the mountain's summit.
Officials have warned residents to stay away from rock and debris flows known as lahars, which have been spotted flowing down from the mountain.
How close is it to a major eruption?
The National Board for Disaster Management raised the alert to level four from 06:00 local time (22:00 GMT Sunday), because of "the possibility and imminent risk of disaster".
The volcano was seen emitting "continuous ash puffs" occasionally accompanied by "explosive eruptions" and "weak booms" that could be heard 12km (7 miles) away from the summit.
