  1. Tohoku Tsunami Seen in Ionosphere Using GPSCompared with JPL’s Song Tsunami Model Earthquake: 05:46:23 UT Observations from ~1200 GPS receivers One of 1200 GPS receiver observations - Tsunami generates atmospheric gravity waves that propagate to ionosphere. - Allows imaging of tsunami using GPS Total Electron Content. Potential application: - Real-time tsunami monitoring and early warning Attila Komjathy (335G), David Galvan (335G), Y. Tony Song (3244), Tony Mannucci (335G)

  2. Tohoku Tsunami Seen in Ionosphere Using GPSCompared with JPL’s Song Tsunami Model Observations from ~1200 GPS receivers Tsunami generates atmospheric gravity waves that propagate to ionosphere. Allows imaging of tsunami using GPS Total Electron Content (TEC). Potential application: -Real-time tsunami monitoring and early warning Attila Komjathy (335G), David Galvan (335G), Y. Tony Song (3244), Tony Mannucci (335G)
