The force of some tsunamis is enormous. Large rocks weighing several tons along with boats and other debris can be moved inland hundreds of feet by tsunami wave activity. Homes and other buildings are destroyed. All this material and water move with great force and can kill or injure people. Tsunamis can occur at any time, day or night.
Tsunamis can travel up rivers and streams that lead to the ocean.
