New images of Indonesian volcano eruption emerge
New photos have emerged of the eruption of an Indonesian volcano which is believed to have triggered a tsunami killing hundreds.
Images posted to social media by National disaster agency spokesman Sutopo Purwo Nugroho show magma flowing out into the sea along with a large ash cloud.
The Anak Krakatoa volcano situated between Java and Sumatra erupted about 9pm on Saturday night and is thought to have triggered an underwater landslide that brought about a tsunami killing 281 and injuring more than 1000 people.
Volcanologist Heather Handley from Macquarie University has examined the photos and said the photos and videos show clear interaction between magma and water.
"It looks like part of the flank of the volcano is gone and the eruption is not coming out of the top of the volcano anymore – it is very close to the water level or it is coming up through the water," Professor Handley said.
"It looks like a lot of steam, so the magma is heating up the water and converting it as well as the actual eruption."
The academic said the dark clouds seen above the volcano were typical of a "wet" eruption, where magma or lava has to pass through either surface water or the ocean.
The volcano had been intermittently erupting since June but had been active since it began to emerge from the ocean in 1927.
The original Krakatoa volcano killed thousands after a massive eruption in 1883.
