All coastlines around the world are vulnerable to tsunamis, so it's important to know your community's hazard and evacuation plans in case they're needed.
You've likely seen images or video of giant waves crashing onto a beach in Banda Aceh, Indonesia, following a massive earthquake in the Indian Ocean in 2004. Or maybe you've seen video of water breaching walls meant to protect seaside communities in Japan following a magnitude 9.0 earthquake off the nation's coast in 2011.
The waves can be hundreds of miles long but only a few inches to a foot high in the ocean. So for people on ships, it may not be noticeable if a tsunami traveled under the vessel. It's important to note that the series of tsunami waves can continue to arrive every few minutes up to an hour for several consecutive hours. The next wave can come as the previous wave continues to push inland, which will cause more significant destruction.All coastlines around the world are vulnerable to tsunamis, so it's essential to know your community's hazard and evacuation plans in case they're needed.
