Tsunamis travel at very high speeds across an ocean basin. The map above shows the travel progression of the December 2004 tsunami that was generated by an earthquake in the Indian Ocean. Note how the wave struck Sri Lanka and India within two hours and had completely crossed the Indian Ocean in about ten hours. See a larger collection of tsunami maps at Geology.com.
