WASHINGTON, July 15 (Reuters) - Satellites can spot the leading edge of a tsunami, U.S. government researchers said on Wednesday in a study that might lead to better ways of detecting the giant waves and get people out of their way.
They went back and looked at satellite images in the Indian Ocean as the December 2004 tsunami raced across to destroy coastlines in Thailand, Sri Lanka and elsewhere. They found clear patterns in the water.
"We've found that roughness of the surface water provides a good measure of the true strength of the tsunami along its entire leading edge," Oleg Godin of the National Oceanic and Atmospheric Administration in Boulder, Colorado, said in a statement.
