On October 17, 1989, the Loma Prieta earthquake struck Northern California, causing widespread damage to the San Francisco Bay Area. The 6.9 magnitude earthquake killed 63 people and injured over 3,700 others. It caused significant destruction in San Francisco, particularly the collapse of a portion of the Bay Bridge and the collapse of buildings in the city. The quake disrupted the World Series, which was being broadcast live when the shaking began. The disaster led to improvements in building codes and emergency preparedness throughout California.
