This article is fascinating — apparently scientists have discovered that an earthquake greater than an 8.0 on the Richter Scale may cause errors with GPS systems. Apparently the shift in the earth may throw off GPS measurements.
This is an interesting look at how Tsunami’s are formed after an earthquake. I am fascinated by the description of the receding water as it rushes out to sea before the momentum turns and it creates a wall of water headed towards land.

I also recall the little girl vacationing during the Indian earthquake who recognized the draining sound taught to her as a key indicator of a tsunami. That bit of knowledge saved lives.
So remember, if you are ever on the coastline, after a local earthquake or one on the other side of the ocean, please keep in mind… if the ocean recedes quickly and or you hear a draining noise from the water as it rushes out to sea…. RUN… RUN as fast as you can for the highest point you can possibly find. In fact, whenever I visit the beach, I always scope out the highest point and the easiest route if I need to get my family to higher ground.
