Major property damage i… Ground Shaking AnimationsTo better understand the distribution of shaking from past and anticipated future earthquakes, seismologists have constructed computer models of earthquakes and the resulting ground shaking. Death, destruction, and havoc were again visited upon the San Francisco area in 1989. Loma Prleta ruptured the southernmost 30 miles of the break that caused the 1906 San Francisco Earthquake. It was the strongest earthquake to hit the area since the San Francisco earthquake of 1906. The earthquake measured 7.1 on the Richter scale, classifying it as "major".The earthquake ran along the San Andreas Fault, the epicenter was located near the Loma Prieta peak in the Santa Cruz Mountains. The investigations evaluate the tools available to the research community to measure the nature, extent, and causes of damage and losses. In Part 2 (of.

That particular day … Oakland City Hall was evacuated after the earthquake until a US$80 million (equivalent to US$165 million today) seismic retrofit and hazard abatement work was completed in 1995. This effort represents just one of the many ways CGS strives to fulfill its mission to provide scientific products and services about the state's geology, seismology and mineral resources—including their related hazards—that affect the health, safety, and business interests of Californians.
