How do you know a tsunami is coming?
6 One sign of a tsunami is when the water level along coastlines changes (either by rising or falling) rapidly. In countries that don't have warning systems for tsunamis, the first thing people might see are stronger waves like the ones in an ordinary storm. These are followed quickly by the big tsunami waves.
7 The United States has warning systems in place to help protect people in Hawaii and on the West Coast, where tsunamis can hit. Scientists and researchers monitor for signs of a tsunami (like an underwater earthquake). If they notice something, they notify organizations to warn people through TV and radio announcements and with warning sirens.
Could a tsunami happen where I live?
8 In the United States, Alaska, Hawaii, and the coasts of Washington, Oregon and California are most at risk. In fact, tsunamis hit Hawaii about once a year. Most aren't dangerous. In fact, damaging tsunamis only hit about once every seven years.
