2 Dr. Herman Fritz surveys of December 26, 2004 Tsunami DEATH ZONE WAS AREA BELOW 10 METERS and LESS THAN 1 KILOMETER FROM SHORE. DEATH ZONE WAS AREA BELOW 10 METERS and LESS THAN 1 KILOMETER FROM SHORE.

3 Sri Lanka Multiple Tsunami Waves Most witnesses described 3 main waves. Most witnesses described 3 main waves. The first knocked them off their feet, the second picked them up and carried them, often up to 50 km/hr, and the third bore them up to 15 meters high or sucked them under.

Evacuate all areas below 15 meters above sea level and within 0.25 mile of shoreline or along rivers. Evacuate all areas below 10 meters above sea level and within 1.0 mile of shoreline or along rivers. Evacuate all areas below 10 meters above sea level and within 1.0 mile of shoreline or along rivers. Evacuate all areas below 5 meters above sea level and within 3 miles of shoreline. Evacuate all areas below 5 meters above sea level and within 3 miles of shoreline.
