What Causes a Tsunami to Travel So Far?

Tsunamis can travel far because they start in deep water and move very fast. Imagine a big stone being dropped into a calm lake, the ripple moves out, getting smaller as it goes. In the ocean, tsunamis are like that ripple, but much bigger and faster. When they reach shallow water near the shore, they grow taller and hit with more force.
