I’ve found two NOAA maps showing the progress and impact of the tsunami generated by this morning’s 8.8-magnitude earthquake in Chile. Note that the wave is happening as I write this and that by the time you read this post these maps may well be out of date.

This map shows the estimated travel times for the tsunami wave:

Via Phil Plait, this map projects the spread of the quake’s energy across the Pacific Ocean:

Phil says: “It’s unclear to me just how big a wave this means in terms of real height (it’s a model, not an actual measurement), but it should bring home that you should take this seriously.”

The Pacific Tsunami Warning Center has no equivalent maps, but does have plenty of data.
