Thread:Comments:8.9 magnitude earthquake hits Japan, causes tsunami/A map with "live" simulated wavefront?

For moments like this it would be interesting to have a map displaying an approximate "live" simulated wavefront of the tsunami (an ideal system would actually run simulations of the wave instead of just expand a circle in function of time, and update the simulation as the events happen in case reality disagrees with the simulation to keep it less far from realty).
