Merging Waves

In March Japan was hit with a high magnitude earthquakes and then a tsunami that killed thousands. Today scientists said that the huge wave was caused by merging waves. At least two or more waves had to merge together for this wave to be so powerful. Ocean ridges and mountains below the water were able to channel the waves caused by the large earthquake.

I found this to be a great article. Researchers have not be able to observe merging waves before now. Scientists used data from satellites to observe this behavior. Also, they now are able to predict some risks for tsunamis in the future. This made me think of our labs and how some of the tools are used to prevent risk. Now scientists can better forecast the tsunami danger all around the world.
