Earthquake Animation


This sequence of intensity maps shows how the intensity grows as a fault rupture increases in length. This sequence, shown for the northern Hayward fault, starts from a hypothetical magnitude 5 and grows to a magnitude 7.1 earthquake. The dynamic rupture process in this hypothetical earthquake would occur in about 8 seconds.
