Japan Earthquake DetailsA massive 9.0 earthquake hit along the coast of Japan, at the pacific coast of Tokoku, on March 11, 2011. It is the fourth largest earthquake ever recorded. The earthquake is a result of two floating tectonic plates forcing pressure against one another. In this case, the Pacific Plate and Ohkotsk Plate slowly created massive pressure for thousands of years. Eventually the pressure becomes too great and one of the plates slips up (technically slip slip). In this case, the Pacific plate shot up 50 feet for over 150 miles instantly. The great force of the shifting earth pushed the water violently upward and created the massive tsunamis with waves over eight feet high with enough power to travel the entire ocean to other nations. And, due to its location, will be one of the most devastating. To date, there are over 2,700 people that have died and the devastation is estimated at over 112 billion dollars. Over fifty nations are rendering aid. People from all over the world are rendering financial and on the ground support. Our hearts go out to the Japanese people and we especially thank those involved in rescue efforts. Sesmological SystemsJapan has had great earthquakes before (Kyoto for one). Their scientists have been trying to predict these earthquakes for years, but they aren't predictable. In any case, Japan has some of the best earthquake data and predictive warning systems available. The USGS has some old Japanese documents that confirm warnings of future North American Earthquakes.
