A desperate exodus underlines the level of fear along Indonesia's gutted coastline after the volcano-triggered tsunami struck without warning, killing over 400 people.
Mount Mayon is characterised as a stratovolcano, meaning a volcano consisting of multiple layers of lava and ash. In the past, its eruptions have occurred within 10 years of one another
More than 40,000 people have already fled since smoke and ash started spewing from the mountain, with scientists warning of the danger of an explosive eruption and authorities urging people not to be complacent.
Lava was slowly flowing out of the Mayon volcano's crater along with a spectacular 1,000-metre (3,280-foot) ash plume rising into the sky, the nation's volcanology institute said.
The 10-kilometre radius around Mount Agung is littered with roadside signs that read "Volcanic danger zone. No entry!", underscoring the potential risks.
