November 5th was World Tsunami Awareness Day. A day to help spread awareness among people across the world who are at risk of experiencing a tsunami. This day raises awareness of the dangerous effects of tsunamis and the importance of early warning signs and preparedness for tsunamis.
How to Identify a Tsunami
A tsunami can be identified by the following warnings:
- Strong or long earthquakes
- Loud roar coming from the ocean
- Unusual ocean behavior; fast rising floor, wall of water, or draining away suddenly showing the ocean floor
Tsunamis can kill or injure people and damage or destroy buildings as waves come and go. Tsunamis are typically caused by earthquakes, underwater landslides, volcanic eruptions, or asteroids.
If a tsunami warning is given:
- Protect yourself from an earthquake; drop, cover, and hold on
- Get to high ground as far inland as possible
- Be alert to signs of a tsunami
- Listen to emergency information and alerts
- Evacuate; do not wait, leave as soon as you see or hear tsunami warnings
- If you are in a boat, go out to sea
Prepare Yourself Now
If you live near oceans, learn about tsunamis in your area. Know the safest evacuation routes. Learn the signs of potential tsunamis. Create family emergency communication plans. You can also sign up for any tsunami alert system.
After a Tsunami
After a tsunami occurs:
- Listen to local alerts and authorities for information on areas to avoid and shelter locations
- Avoid wading in floodwater as water can be deeper than it appears, and the water can contain dangerous debris
- Be aware of electrocution risks
- Stay away from damaged buildings, roads, and bridges
