NASA helps test tsunami prediction system

GPS used to predict the size of tsunamis

A NASA-led research team has demonstrated a prototype tsunami prediction system that estimates the size of waves after large earthquakes.
The government agency released information Monday about use of the prototype to predict a tsunami following the magnitude 8.8 Chilean earthquake on Feb. 27.
?This successful test demonstrates that coastal GPS systems can effectively be used to predict the size of tsunamis,? Y. Tony Song, team leader for the project, said in a statement. ?This could allow responsible agencies to issue better warnings that can save lives and reduce false alarms that can unnecessarily disturb the lives of coastal residents.?
