Animations show how the Chilean earthquake-generated tsunami spread across the Pacific and beyond.
NOAA's Center for Tsunami Research has generated some impressive animations of the February 27th Chilean tsunami. There are actually several animations, though you'll need to go to the NOAA website to play them. One is a wave amplitude animation. Another's a wave amplitude over time animation, but with a more wavelike look to it. There are also energy propagation plots displayed on Google maps or on Google Earth.
From the NOAA Chile event page:
"The Chile tsunami was generated by a Mw 8.8 earthquake (35.846°S, 72.719°W ), at 06:34 UTC, 115 km (60 miles) NNE of Concepcion, Chile (according to the USGS). In approximately 3 hours, the tsunami was first recorded at DART® buoy 32412. Forecast results shown below were created with the NOAA forecast method using MOST model with the tsunami source inferred from DART® data. The tsunami waves first arrived at Valparaiso, Chile (approximately 330 km northeast from earthquake epicenter ) earlier than other tide gages, at 0708UTC, about 34 minutes after the earthquake."
