How to Read Tsunami Hazard Maps for Safety?

Understanding the Map

When reading a tsunami hazard map, you’ll notice different zones and colors that indicate varying levels of risk. Typically, the map will use a color-coding system ranging from green (low hazard) to red (high hazard). The legend will explain the colors and corresponding evacuation times. For example, a map may have a 1- to 3-minute evacuation time for areas within a few hundred feet from the coast. Pay attention to the specific numbers and times indicated on the map, as they may vary depending on the location and severity of the tsunami.

Identifying Evacuation Routes and Zones

The map will also show evacuation routes and zones, including the safest routes to higher ground or designated assembly points. Look for symbols indicating the nearest evacuation routes, such as arrows or footprints. Understand the map’s notation for different zones, such as " tsunami evacuation zone" or " tsunami inundation zone." Familiarize yourself with the closest evacuation routes and assembly points, and make sure to share this information with your family and neighbors.

Preparing for the Tsunami Warning

In the event of a tsunami warning, quickly scan the map to identify your location and the nearest evacuation zone. If you’re in a high-risk area, grab essential items such as a first-aid kit, water, and a battery-powered radio, and head immediately to higher ground or a designated assembly point. Stay alert and follow evacuation instructions from local authorities, which may include specific warnings or evacuation routes. Remember, the key to survival is speed and awareness – quickly understanding the map and acting on evacuation instructions can save your life.
