Quick Answer
To avoid a tsunami, move inland at least 100 yards (91 meters) or higher in elevation. This distance and elevation provide a safe buffer zone from the tsunami wave's impact. The exact distance may vary depending on the local terrain and the tsunami's intensity.
Understanding Tsunami Risks and Terrain
When a tsunami warning is issued, your priority is to quickly move to a safe location. The safest terrain for avoiding a tsunami is high ground, such as hills, mountains, or elevated plateaus. Avoid low-lying coastal areas, beaches, and riverbanks, as these areas are most susceptible to tsunami damage.
Measuring Distance and Elevation
To measure the distance and elevation, use the following techniques: (1) Identify the highest point within a 1-mile radius of your location. (2) Measure the distance from your location to this point, aiming to reach it within 10-15 minutes of walking. (3) Calculate the elevation gain required to reach the safe point, aiming for at least 100 yards (91 meters) of vertical separation from the coastline.
Executing a Rapid Evacuation
When executing a rapid evacuation, consider the following tips: (1) Stay away from buildings near the coast, as they may collapse or be swept away. (2) Move in a group, as this will increase your visibility and help others follow your lead. (3) Stay informed about the tsunami’s progression and adjust your evacuation route accordingly.
