How is a Tsunami formed?
Tsunami's can be caused by a nuclear explosion, eruption, landslides, earthquakes and meteorite. So when one of those things happen it sends a vibration of energy through the water, then as it get closer to land it rises taller but it starts to reduce its speed. The giant wave moves more slower as it gets to land because the water depth is lower so it can't draw as much water as it did in the deep ocean water. Then it will slowly approach land, then CRASH it hits land!
