The Indonesian volcano which caused a tsunami that killed more than 400 people last week lost more than two-thirds of its height following the eruption which triggered the tsunami waves.
A section of Anak Krakatoa’s crater collapsed into the seas after an eruption, which generated the tsunami last Saturday 22 Dec 2018 night.
Anak Krakatoa used to stand tall at 338 metres high. Now its height was dropped to just 110 metres tall losing at least 228 metres.

It terms of its volume, it was reported that Anak Krakatoa lost between 150-170 million cubic metres of its volume. Only 40-70 million cubi metres of remains. The loss was said to be caused by the high eruption rate between 24 to 27 Dec 2018 (Monday to Thursday).
Japan’s space agency took before and after stellite images, which showed that a two square kilometre chunk of the volcanic island had collapsed into the water.
“Anak Krakatoa is now much shorter, usually you can see the peak from the observatory post, now you can’t,” Wawan Irawan, a senior official at the agency, told AFP.
