Tsunami unleashed by Anak Krakatoa eruption was at least 100m high

The deadly volcanic eruption of Anak Krakatoa in 2018 unleashed a wave at least 100m high that could have caused widespread devastation had it been travelling in another direction, new research shows. Over 400 people lost their lives in December 2018 when Anak Krakatoa erupted and partially collapsed into the sea, sending a wave westward towards the Indonesian island of Sumatra that was between 5 and 13 metres high when it made landfall less than an hour later. However, new analysis from researchers at Brunel University London and the University of Tokyo has shown that the disaster wreaked could have been significantly worse had the wave—which started between 100m and 150m high—been travelling towards closer shores. "When volcanic materials fall into the sea they cause displacement of the water surface," said Dr. Mohammad Heidarzadeh, an assistant professor of civil engineering at Brunel, who led the study. "Similar to throwing a stone into a bathtub—it causes waves and displaces the water.
