1989 Loma Prieta earthquake Area's automobile transportation landscape. Not only did the quake force seismic retrofitting of all San Francisco Bay Area bridges, it caused enough damage that some parts of the region's freeway system had to be demolished. Damage to the region's transportation system was estimated at $1.8 billion. The 1989 World Series featured the Oakland Athletics and the San Francisco Giants in the first cross-town World Series since 1956. Game 3 of the series was scheduled to begin at San Francisco's Candlestick Park on October 17 at 17:35 PDT, and American TV network ABC began its pre-game show at 17:00 PDT. When
1989 Loma Prieta earthquake about from the epicenter. From October 5, they reported that a substantial increase in noise was measured in the frequency range 0.01–10 Hz. The measurement instrument was a single-axis search-coil magnetometer that was being used for low frequency research. Precursor increases of noise apparently started a few days before the earthquake, with noise in the range 0.01–0.5 Hz rising to exceptionally high levels about three hours before the earthquake. Though this pattern gave scientists new ideas for research into potential precursors to earthquakes, and the Fraser-Smith et al. report remains one of the most frequently cited examples of a specific
