Transcript for Computer Animation of Loma Prieta Aftershocks, segment 05 of 12


{{{MUSIC}}}

The green circles are selected aftershocks from the first fourteen days of the sequence. You will see a time lapse animation of the first five days of these aftershocks, which will be shown in yellow. 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 for two frames. An earthquake is thus on the screen for three frames, or three hours. The animation is played twice.
