ABAG Animation of Shaking Due to an Earthquake on the Hayward Fault
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.
