Recent Samoan tsunami was up to 46 feet high

Hard to imagine how anything could have survived such a hit.

The massive waves that struck Samoa, American Samoa and Tonga totally destroyed traditional wooden buildings, many of them singly story, along the coast while reinforced concrete buildings sustained only minor damage, said Stefan Reese, a risk engineer with New Zealand's National Institute of Water and Atmospheric Research.

The waves were up to 46 feet (14 meters) high, Reese told The Associated Press. The scientists measured watermarks on buildings and trees to help confirm the height of the waves.

"In some areas there was virtually nothing left" after the waves reached up to 765 yards (700 meters) inland, Reese said.
