The earthquake simulation starts to the north, near Parkfield, and ruptures southeastward. The colors (white depicts the most intense shaking) show the amplitude of the waves as they are generated on the fault and radiate to surrounding areas. The number in the top right corner lists the time since the initiation of the earthquake. Notice how areas such as Ventura, Los Angeles, San Bernardino, and the Coachella Valley generate some of the strongest (and longest duration) shaking, due to amplification of the underlying sedimentary basins. San Diego feels the shaking about 2 minutes after the earthquake starts. Finally, 5-6 minutes after the start, the last waves dissipate in the Imperial Valley and northern Baja.
