The active volcano blew its top shortly after 9pm local time (2pm GMT). The eruption led to an underwater landslide which triggered a vast tsunami. At least 62 people were killed by the ensuing wave, with 600 more injured, according to authorities in the Southeast Asian nation.
The tidal wave made landfall at roughly 9.30pm local time (2.30pm GMT), obliterating the homes of 430 people and almost completely wiping out entire communities.
Indonesian officials believe the tsunami was caused by an eruption on nearby Krakatoa, which has been spewing volcanic ash into the air.
The Australian Bureau of Meteorology has been monitoring the situation and has issued a red warning to airline pilots operating in the region that an ash cloud is spreading south-west from the volcano to an altitude of 55,000 feet.
The ash cloud could wreak havoc with thousands of people’s travel plans as they make their Christmas getaways.
The country’s Disaster Mitigation Agency confirmed roughly 600 people have been injured as a result of the natural disaster.
A further 20 people are believed to be missing.
Horrific scenes were caught on videos and posted to social media.
Some footage showed people being rescued from the rubble as emergency services scrambled to save those affected by the massive calamity.
Another clip showed the moment a rock band was entirely swamped by the wave while playing to an audience on stage.
And another video showed the moment the wave hurtled into a small town community.
Commenting on the footage, Sutopo Purwo Nugroho, an Indonesian civil servant and head of public relations at the Indonesian National Board for Disaster Management said in a tweet: “It shows the impact of the tide on the coast of Anyer Pandeglang Regency South Lampung, which left one person dead and 11 people injured.
“The wounded were treated in hospital.”
Mr Nugroho speculated the “cause of the tsunami in Pandeglang and South Lampung is possibly a combination of underwater landslides due to the influence of the eruption of Anak Krakatoa (child of Mount Krakatoa) and the high tides caused by the full moon”.
