In a reminder of how powerful last year's Asian earthquake and tsunami actually were, scientists working at the Pacific Marine Environmental Laboratory in Seattle published a study in Science Express that says that their research confirmed tidal gauges around the world detected the approaching tsunami and that it was tracked by satellite.
By the time the wave reached other parts of the world it was between three and twenty inches high. Other nations were spared the thirty foot monster wave that slammed into South Asian nations and killed hundreds of thousands of people and made millions homeless.
Our understanding of how currents and underwater ridges affect wave patterns has been increased exponentially by the tsunami and the information is still coming in.
