Indonesia tsunami worsened by shape of Palu bay: scientists

Indonesia tsunami worsened by shape of Palu bay: scientistsThe tsunami that ravaged the Indonesian city of Palu was outsized compared to the earthquake that spawned it, but other factors — including a long, narrow bay — conspired to create monster waves, scientists say. The 7.5-magnitude quake, which struck early evening on Friday — a time when many in the Muslim-majority country would have been at the mosque — brought buildings down all over Palu and its surrounding area. “The waves were at least two-to-three metres high, and possibly twice that,” said Jane Cunneen, a research fellow at Curtin University’s Faculty of Science and Engineering in Bentley, Western Australia, and an architect of the Indian Ocean’s tsunami warning system, developed under UN guidance.
