Tsunami prediction gets help from satellites imageries

 Newly released imagery from NASA spaceborne instruments sheds valuable insights into the Indian Ocean tsunami on December 26 2004.

The Multi-angle Imaging SpectroRadiometer imagery includes the only known animations produced by a remote sensing instrument to capture tsunami waves in motion as they make landfall. The image set and animations were collected December 26 as Terra spacecraft passed over the eastern Indian coast about an hour and a half after the first waves hit shore. Together with measurements of ocean depth, these data can be used to refine models of how tsunamis originate and travel. Better understanding of how tsunamis interact with coastal areas is one factor needed to improve near-real-time forecasts of tsunami arrival times and effects, and to reduce damage from such waves in the future.

I'm somewhat surprised to discover that there wasn't a satellite in stationary orbit that was capable of recording the whole thing.

NASA has let me down.
