Over the last few decades, advancement in our understanding of the dynamics of the earth's surface and the geology of the Cascadia region has revealed that this region is subject to high intensity earthquakes. This is a result of the collision of large elements of the earth's crust called plates. Earthquakes of this type occur less frequently than those from horizontally moving faults like the San Andreas, but they are often of much larger magnitude.
