(Tuesday, October 17, 1989, 5:04:15 p.m. PDT; during the 1989 Loma Prieta earthquake) — An earthquake measuring 7.1 on the Richter scale struck today in northern California, killing 63 people, injuring another 3,757 people and causing $6 billion worth of damage.

Because the quake hit during a national live broadcast just before the scheduled start of Game 3 of the World Series in San Francisco between the Giants and the Oakland A’s, it is sometimes referred to as the “World Series earthquake.”

The shock, the most powerful California earthquake since the legendary temblor of 1906 struck the San Francisco Bay area, was centered in The Forest of Nisene Marks State Park approximately 10 miles northeast of Santa Cruz on a section of the San Andreas Fault System and was named for the nearby Loma Prieta Peak in the Santa Cruz Mountains.

The worst disaster of the earthquake was the collapse of the double-deck Cypress Street Viaduct of Interstate 880 in West Oakland. The failure of a 1.25-mile section of the viaduct, also known as the “Cypress Structure” and the “Cypress Freeway”, killed 42 and injured many more.

The San Francisco–Oakland Bay Bridge also suffered severe damage, as a 76-by-50-foot section of the upper deck on the eastern cantilever side fell onto the deck below.

Four people died in San Francisco’s Marina District, four buildings were destroyed by fire, and seven buildings collapsed.

Rush-hour traffic on the Bay Area freeways was lighter than normal because the game, being played at Candlestick Park in San Francisco, was about to begin, and this may have prevented a larger loss of life, as several of the Bay Area’s major transportation structures suffered catastrophic failures.
