2. You're not out of danger after the first wave of a tsunami.
第一波海啸结束并不意味着脱险
A tsunami occurs as a series of waves known as a "wave train," and the series of surges can be five minutes or up to an hour apart. The tsunami does not usually appear on the shoreline as a gigantic breaking wave, but rather as a rapid tide or a wall of water. The worst mistake you can make is staying near the beach out of curiosity. Find higher ground and go as far inland as you can. If you can see the waves, you're still too close.
