Tsunami Early Warning

There may be an early warning signal for major subduction zone earthquakes.

"'In areas along subduction zones, like the Northwest coast of the United States, we should look to see where the land has subsided and put instruments there to monitor it,' said Jere Lipps, a UC Berkeley professor of integrative biology and study coauthor. 'If the land continues to subside instead of relaxing back to normal, it could indicate a big earthquake and a tsunami might occur some time in the next few years.'"
