How it Works(Emergency Alert System, EAS): Emergency Alert System (EAS) - SCD EOC initiates public message, - Transmits immediately by dedicated microwave link - Designated radio stations - neighbor islands - TV broadcasts (crawlers) originate from Honolulu Tsunami Evacuation Mapslocated in the front of Telephone White Pages SENSE-ing a Tsunami TOUCH Strong local earthquakes may cause tsunamis. FEEL the ground shaking severely? Evacuate low-lying coastal areas and move inland to higher ground! SIGHT As a tsunami approaches shorelines, water may recede from the coast, exposing the ocean floor and reefs. SEE an unusual disappearance of water? Evacuate low-lying coastal areas and move inland to higher ground! SOUND The abnormal ocean activity, a wall of water, and approaching tsunami waves create a loud “roaring” sound similar to that of a train or jet aircraft. HEAR the roar? Evacuate low-lying coastal areas and move inland to higher ground! Local Tsunami Warning Evacuation PTWC issues an urgent tsunami warning for local earthquakes magnitude 6.9 or greater. County Warning Points sound sirens in designated Counties (e.g. Hawaii and Maui Counties). National Weather Service broadcasts warning and evacuation through the EAS.
