Tsunamis travel across oceans at 500+ mph and can strike coastlines with waves reaching 100+ feet.
Why Tsunami Preparedness Matters Now
A Cascadia Subduction Zone event could generate a tsunami reaching shore in just 15-30 minutes.

Frequently Asked Questions
How much warning time?
Local tsunami: 15-30 minutes. Distant tsunami: 3-12 hours. For local events, the earthquake itself is your warning.
How far inland can it travel?
Up to 10 miles in flat coastal areas. Elevation matters more than distance. Reaching 100 feet above sea level provides safety.
Does the ocean recede first?
Sometimes, but not always. Never wait for this sign. If you feel a strong earthquake near the coast, move to high ground immediately.
Can tsunamis happen on the East Coast?
Yes, though lower risk. Atlantic tsunamis can come from Caribbean earthquakes, volcanic collapses, or submarine landslides.
What if I’m on the beach?
Move immediately to high ground or as far inland as possible. Go on foot if roads are congested. If no high ground, go to 3rd+ floor of reinforced concrete building.
