Transcript for Computer Animation of Loma Prieta Aftershocks, segment 06 of 12
This is a view of the Santa Cruz Mountains from space.
You are looking at the San Andreas Fault from the side. The green circles are selected aftershocks that occurred on the fault during the first fourteen days of the sequence. The earthquakes in yellow make a time lapse animation of the first five days of aftershocks. As before, each frame of the animation steps ahead one hour. An earthquake is plotted as a solid circle on one frame, then as an open circle on the next two frames. An earthquake is thus on the screen for three frames, or three hours. The animation is played twice.
