Waves: destructive energy and power

The earthquake zones off of certain coasts – like those of Japan and Java - make them especially vulnerable to tsunamis.

The new study authored by Utku Kanoglu and Costas Synolakis has changed the way scientists explain the rules of tsunami. Until now, it was largely believed that the maximum tsunami height onshore could not exceed the depth of the seafloor.

The recent research shows that when focusing occurs, the scaling relationship breaks down and flooding can be up to 50 percent deeper with waves that do not lose height as they get closer to shore.

Federal District Court Judge Carl Barbier in New Orleans will decide whether BP's actions on the drilling rig were negligent – as has already been determined in the criminal case – or grossly negligent, which could force the company to pay significantly higher fines.
