By the way, if you guys remember that tsunami that hit the Indian Ocean back in 2004 the magnitude of the Japan earthquake is similar this. Back in 2004 the magnitude of that earthquake was so huge that it tilted the earth's axis by a few degrees. I dont know if you guys remember but this caused abnormal season changes throughout the world. This Japan earthquake may also cause the earth tilt again by a few degrees. Therefore, you may be expecting weird weather in the future.
About the Earth's axis tilting a few degrees that is inaccurate from what I've learned Astronomy class, it did tilt but not by a whole much, I'll have to get back to you on that.
