The eruption of Indonesia's Mount Sinabung, which shot ash five kilometres high, also "annihilated" the mountain's summit.

Before and after images from Indonesia's Centre for Volcanology and Geological Hazard Mitigation show an enormous chunk missing from the peak.

Volcanologist Devy Kamil Syahbana said the chunk, known as the "lava dome", had a volume of at least 1.6 million cubic metres (56.5 million cubic feet).

The volcano in North Sumatra, which has been active since 2010, erupted explosively on Monday morning.

Hot ash clouds rolled down its slopes, travelling as far as 4.9 kilometres from the crater.

Rumbling Mount Sinabung on the Indonesian island of Sumatra shot billowing columns of ash more than 16,400ft (5,000m) into the atmosphere and sent hot clouds down its slopes.

There were no fatalities or injuries from the morning eruption, the National Disaster Mitigation Agency said.

The volcano, one of three currently erupting in Indonesia, was dormant for four centuries before exploding in 2010, killing two people.

Another eruption in 2014 killed 16 people, while seven died in a 2016 eruption.

Disaster agency spokesman Sutopo Purwo Nugroho said hot ash clouds travelled as far as three miles (4.km) south.

The regional volcanic ash advisory centre in Darwin, Australia, issued a 'red notice' to airlines.

Some 30,000 people have been forced to leave homes around the mountain in the past few years.
