Why does a tsunami move faster than a regular wave?

Answer 1

That's because a tsunami contains thousands of more gallons than a regular wave. Example: In a bowling lane, a bowling ball (tsunami) is heavier and it can easily knock down pins. It's fast and heavy. If you tried to knock over the pins with a bouncy ball (regular wave), not much pins would be knocked over.. Though this explains why a tsunami can do so much damage, it does not explain how it moves faster. in a bowling alley both a bowling ball and a bouncy ball would move at the same speed.
