Keeping people safe from tsunamis
Alaska has the greatest potential for earthquakes and tsunamis in the entire United States. The communities of southern amd coastal Alaska occupy one of the most seismically active regions of the world,
where the Pacific plate is subducting under the North American plate.
When community emergency management personnel see the inundation mapping results and assess the hazard in an area, they can establish evacuation routes and safe zones. Many communities have sirens in place to alert residents of tsunami warnings.
The most important thing for residents in coastal communities is to be aware and have a plan. A strong earthquake felt in a low-lying coastal area is a natural warning of possible danger. Not all large earthquakes cause tsunamis, but many do.
