This is because all the energy of the wave is concentrated into a smaller space, which causes the wave to grow higher. Once again, Japan sets the standard. Individuals can take steps to be prepared for a tsunami, and warning systems can help get people out of harm's way if an impending tsunami is predicted. Fact Check: Is the COVID-19 Vaccine Safe? But we can and are developing more sophisticated monitoring systems to detect underwater seismic activity which in turn will make early warning systems work better and help people get the time they need to get to safety. A Tsunami watch means a dangerous tsunami has not yet been verified but could exist and may be as little as an hour away. You should be safe from nearly all tsunamis when you reach the third floor.

The fifth floor should be above even the highest earthquake-generated ocean tsunamis. Because of the unique nature of building a tsunami-resistant structure, the U.S. Federal Emergency Management Agency (FEMA) has a special publication called Guidelines for Design of Structures for Vertical Evacuation from Tsunamis . Even shoreline forests, if they are large enough, can protect areas behind them. This myth is not true. All government, local authorities, emergency services, schools, and most large businesses in vulnerable regions have mandatory tsunami evacuation drills at regular intervals. Unfortunately people often fail to prepare themselves or their homes from earthquake damage.
