Unlike previous earthquakes such as San Francisco in 1906, when the plates shifted a maximum of 6.4 M (21ft) relative to each other no fault plane or rifting was evident at the surface in the 1989 Loma Prieta, California, area. Instead, the fault plane suggested in Figure12.19 shows the two plates moving horizontally approximately 2 m(6ft) past each other deep below the surface, with the Pacific plate thrusting 1.3 m upward. This vertical motion is unusual for the San Andreas fault and indicates that this portion of the San Andreas system is more complex than previously throught. Damage totaled $8 billion, 14000 people were displaced from their homes, 4000 were injured, and 67 were killed.
