1989 - Loma Prieta Earthquake
During warmups for Game 3 of the 1989 World Series between the Bay Area rivals Giants and Athletics, the Loma Prieta earthquake struck, causing significant damage in both San Francisco and Oakland. Since the temblor occured at 5:04 p.m., only minutes before the start the Oct. 17 game at Candlestick Park, it became the first major earthquake ever broadcast on live television.
The game was immediately postponed and ABC-TV ran live coverage of the disaster using play-by-play man Al Michaels as its on-the-scene reporter. San Francisco mayor Art Agnos wanted a month-long delay and Major League Baseball would have played the series elsewhere if the venues were proved unsafe. The series returned to the 'Stick after a 10-day suspension and the A's finished their four-game sweep.
Ultimately the World Series helped to save many lives that day, as the early game time kept many people off the roads who otherwise would have been in the midst of their rush hour commute.
