SUNDA STRAIT, INDONESIA — The tsunami killed at least 373 people and severely damaged infrastructure.<br /><br />A tsunami struck coastal towns on the islands of Sumatra and Java, Indonesia on Saturday.<br /><br />The tsunami was caused by an eruption from Anak Krakatau, a volcanic island that sits in the Pacific "Ring of Fire" in the Sunda Strait.<br /><br />According to Reuters, the eruption caused a 64-hectare portion of the volcano to collapse into the ocean triggering an underwater landslide that would set off the tsunami.<br /><br />No warning system was triggered at the time of the tsunami. Indonesian officials stated that their tsunami buoy network has not been operational since 2012.<br /><br />According to The Guardian, if a buoy network had been installed around Anak Krakatao, it would have given surrounding towns a maximum of a one-to-two minute warning ahead of pending waves."<br /><br />The tsunami demolished over 700 buildings and left hundreds dead or missing just 24 hours after the volcanic landslide.<br /><br />Anak Krakatao is one of 76 active volcanoes in Indonesia.
