  2. Hambantota, Sri Lanka • Dr. Hermann Fritz surveyed after December 26, 2004 Indian Ocean Tsunami • Noted that it was similar to Hawaii Kai with reef outside with a channel under a road along the sea shore into a large shallow lake.

  3. HAMBANTOTA, SRI LANKADecember 26, 2004 Tsunami • DEATH ZONE WAS AREA BELOW 10 METERS and LESS THAN 1 KILOMETER FROM SHORE.

  4. Sri Lanka Multiple Tsunami 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.

  5. Fritz Indian Ocean Tsunami Survey Conclusions • 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 5 meters above sea level and within 3 miles of shoreline.

  6. The Fritz Indian Ocean Evacuation Criteria • Consider the 1946 historical observations as recorded in • United States Tsunamis - 1690-1988 (page 66) • Waipio Valley - 12 meter run-up amplitude • Swept 1 mile into valley, pulled away homes and people • and left only foundations • Waikolu Valley, Molokai - 16.4 meter run-up amplitude • Destroyed farms and buildings up entire valley. • Makapuu Point, Oahu - 11.1 meter run-up amplitude • Destroyed the nearby Ranch buildings with 3 waves (Helsley • from wave deposits) leaving only foundations. • Three wide valleys destroyed by the 1946 tsunami are • historical evidence that the Fritz Indian Ocean Criteria • is also appropriate for Hawaii .
