One year following Loma Prieta, in direct response to the ground failure caused by the earthquake, the State enacted legislation directing CGS to identify and map areas prone to liquefaction, earthquake-induced landslides and amplified ground shaking. VIDEO: A look back at the hours and days surrounding Loma Prieta EventpageTectonic summary, maps and data. Damage to public infrastructure at or below the ground surface (streets, curbs, and water and gas lines) in southwestern Santa Clara Valley, California, associated with the 1989 Loma Prieta earthquake, is used to support the assertion that the series of photointerpreted lineaments are tectonic in origin and related to long-term reverse faulting along the range front of the Santa Cruz Mountains. As devastating as Loma Prieta was, a magnitude 7.5 earthquake on the Hayward Fault in the East Bay could do $65 billion in damage. It examines how the fault that generated the earthquake ruptured, searches for and evaluates precursors that may have indicated an earthquake was coming, reviews forecasts of the earthquake, and describes the geology of the earthquake area and the crustal forces... Professional Paper 1553 describes how people and organizations responded to the earthquake and how the earthquake impacted people and society.

That particular day … This movie shows shaking intensity as the seismic waves travel away from the earthquake epicenter over time. A total of 1427 damage sites, collected from more than 30 sources, are concentrated in four zones, three of which are near previously mapped faults. It was a tragic reminder of the destructive power of earthquakes. The epicenter was located in the Santa Cruz Mountains west of Loma Prieta Peak on a previously undiscovered fault near the larger and well known San Andreas Fault. 2,575 businesses were damaged and 147 were destroyed. Across the bay area, the quake was responsible for 62 deaths, and damage estimates neared the 5 … Pounding was present over a wide geographical area including the cities of San Francisco, Oakland, Santa Cruz and Watsonville.

This motion typically occurs in sudden jumps during large earthquakes. Land west of the fault has been moving to the northwest relative to land on the east at an average rate of 2 inches per year for millions of year. 30 years later, we revisit the earthquake through the eyes of the scientists who experienced it. Twenty-five years have now passed since the 1989 Loma Prieta earthquake — a 6.9-magnitude temblor — rocked the San Francisco and Monterey bay areas, causing millions of dollars in damages throughout the region.

I don’t feel like it just happened yesterday or anything – I just can’t believe I’m actually that old! Magnitude is a measure of an earthquake's size, but rather than being a dire​ct measure of the level of ground shaking, it is a measurement of the strength of the seismic sound waves given off by the earthquake.
