Episode notes
Massive Earthquake Created Pacific Tsunami
- An 8.8 magnitude earthquake off Russia's coast displaced water upward, creating a tsunami across the Pacific.
- Tsunami waves can travel up to 500 miles per hour, forcing precautionary warnings across the Pacific including the U.S. west coast.
Run When Water Recedes
- If at the beach you see the water suddenly recede far from the shore, run inland immediately.
- This "trough" is the first sign of a tsunami wave about to hit.
Tsunami Waves Affect Coastlines Differently
- Tsunamis consist of multiple waves whose patterns change due to underwater geography.
- Even after warnings are lifted, strong and dangerous water currents remain near the coast.
