The safest place to be in a tsunami is at a location 100 feet or more above sea level, or at least one mile inland.
Here's a more detailed breakdown of tsunami safety and preparedness:
Understanding Tsunami Risks
Tsunamis are powerful ocean waves caused by large-scale disturbances, most commonly underwater earthquakes. They can travel across entire oceans and cause immense destruction upon reaching coastal areas. Understanding the risks is the first step to staying safe.
Key Safety Measures
- Evacuate to Higher Ground: As mentioned, the most critical step is to move to higher ground. The safest options are:
- Elevations of 100 feet or more above sea level: This provides a significant buffer against the wave's height.
- At least one mile inland: Moving this distance inland mitigates the risk of inundation and strong currents.
- Heed Warnings: Pay close attention to official tsunami warnings issued by authorities. Evacuate immediately when a warning is issued. Don't wait to see the wave; tsunamis can travel much faster than you can run.
- Vertical Evacuation (If Necessary): If you cannot reach higher ground or move inland, seek refuge in a sturdy, multi-story building designed to withstand tsunami forces. This is a last resort option, but it's better than being caught in the wave. Ensure the building is specifically designed for tsunami survival; not all buildings are created equal.
- Stay Informed: Monitor official news channels and weather updates for the latest information on the tsunami threat.
Developing a Family Emergency Plan
A well-thought-out family emergency plan can save lives. Here are essential components:
- Communication Plan: Designate an out-of-state contact person. It's often easier to make calls outside the affected area during an emergency.
- Meeting Point: Establish a designated meeting place away from the coast where family members can reunite if separated.
- Emergency Kit: Prepare a kit with essential supplies such as water, food, first-aid supplies, medications, a flashlight, and a radio.
- Community Alert System: Sign up for your community's warning system to receive timely alerts and updates.
After a Tsunami
- Stay Away from the Coast: Do not return to the coast until authorities have declared it safe. Subsequent waves may occur, and the danger is not over after the initial surge.
- Be Aware of Hazards: Be cautious of debris, damaged structures, and contaminated water.
- Assist Others: If possible, help those who may be injured or in need of assistance.
