Document Summary
The region where the fault curves along the outline of ca. Mountains form due to the collision of oblique strike slip fault where the bend occurs. Legislation passed after 1933 long beach earthquake that requires schools be built to a certain standard to be safe in a seismic event. Thrust fault that pushed the shaking northward into the mountains rather than the valley that is highly populated. A whole fault does not usually rupture, only a section. As you move away from the hypocenter/epicenter there is less slip until you reach zero slip. Ruptures along fault with varying amount of slip. Draw a linear regression line along the aftershocks. Diagram of focus and direction of rupture along fault plane. P-wave (primary)- travels fastest and hits rst. Particle motion is in the same direction the wave travels (twice speed of s-wave) S-wave (secondary)- travels slower than p-wave and hits second.
