Ceilings caved in at two high schools and several ancient Hindu temples were damaged, with stones tumbling to the ground and walls crumpling. Some cars in the bustling capital were crushed by falling slabs of concrete. The U.S .Geological Survey said the quake was centred 60 miles (100 kilometres) southwest of the island, famous for its resorts and spectacular surfing beaches. It hit 21 miles (35 kilometres) beneath the ocean floor.
