Friday's catastrophic tsunami event on Sulawesi Island is a puzzle. As the emergency response gathers pace, scientists are scratching their heads to understand why it generated such big waves. The quake was what geophysicists call a strike-slip event, where the ground breaks horizontally. Strike-slip quakes can cause tsunami events but the 6m-tall waves that crashed ashore at Palu city surprised everyone.
