Quick Answer
Evacuating during a tsunami watch is necessary to minimize the risk of injury or death from a potential tsunami. This is because the time between the warning and the arrival of the tsunami can be short, making evacuation the best course of action. If you are in a tsunami-prone area, evacuate immediately when a watch is issued.
Understanding Tsunami Warnings
A tsunami watch is issued by authorities when there is a possibility of a tsunami occurring, usually due to an earthquake or landslide. This warning indicates that a tsunami may impact the area, but it is not yet certain. It is essential to understand the difference between a watch and a warning: a warning means a tsunami is imminent or already occurring.
Evacuation Time and Distance
The time between the tsunami watch and the tsunami itself can be as short as 15-30 minutes. In this time, you need to evacuate to higher ground or a safe location at least 100-200 feet (30-60 meters) above sea level and at least 1 mile (1.6 kilometers) inland. The farther inland you are, the safer you will be. If you are near the coast, move immediately to the nearest high ground or elevated area.
Evacuation Techniques
To evacuate quickly and safely during a tsunami watch, follow these steps: (1) Stay informed through local news and emergency alerts; (2) Know your evacuation route and assemble with your family; (3) Move immediately to higher ground or a designated safe location; and (4) Stay away from the coast and avoid low-lying areas. If you are driving, do not try to outrun the tsunami; instead, find a safe location to park and wait for the tsunami to pass.
