EQ’s are caused by the sudden release of stored elastic energy from rocks in the Earth. This energy release is usually adjacent to a fault and is derived from plate tectonics. As we know, plate tectonics shape the Earth as the massive plates slowly move over, under and past each other, accumulating energy along the way. When this energy becomes strong enough it can be released, and cause devastating aftereffects like the Northridge Earthquake of 1994. Geologists have found that most EQ’s occur along faults, which resemble weakness in the crust of the earth. A Fault is a fracture in the Earth’s crust where two blocks of the crust have slipped with respect to each other. There are 3 different types of faults; Normal, Thrust, and Strike-
