Tsunami Was More Powerful Than Originally Thought.

Data from NASA and European radar satellites captured at least two wave fronts that day. The fronts merged to form a single, double-high wave far out at sea. This wave was capable of traveling long distances without losing power. Ocean ridges and undersea mountain chains pushed the waves together along certain directions from the tsunami’s origin.

The ocean topography had a lot to do with the tsunamis merging. When looking at the data from the buoys and GPS data from Japan along with Reporting of Tsunamis program, the scientists were able to create the simulation.

Scientists now may be able to create maps that take into account all undersea topography, even sub-sea ridges and mountains far from shore. This will help in the prediction of a path that a tsunami may or may not take.

Even though, Japan’s disaster is still being felt today, scientists will hopefully be able to not only create better hazard maps but give warnings to coastlines with better accuracy.

Tsunamis …. as the green future unfolds.
