1906 Ground Motion Simulation
"This computer simulation was created by seismologists at the USGS, in order to better understand the distribution of shaking and damage that happened in the 1906 earthquake, and to better predict ground shaking intensity and damage to structures in future earthquakes. Yellow to red colors indicate regions experiencing damaging shaking." (paraphrased by R. Collins)

"One striking observation for those who experienced the 1989 Loma Prieta earthquake's shaking is the comparison of the extent and intensity of shaking with the 1906 earthquake. The Loma Prieta rupture was about 30 times smaller in energy than the great 1906 earthquake."
If the 1906 earthquake is equated to an auto accident at 75 mph, then the Loma Prieta quake would equal an accident at 13 mph. Feeling secure in future severe earthquakes because of the 1989 experience is like believing seat belts are not needed on the highway because of surviving a parking lot fender-bender.
