The Loma Prieta Earthquake occurred on Tuesday, October 17, 1989. The magnitude was 6.9, the most powerful the state had experienced in several years. Sixty-three people were killed, 3,757 were reported injured and 12,053 displaced. Damage and business interruption estimates reached as high as $10 billion. Structural problems in Intersection’s building, in addition to the Loma Prieta earthquake, forced Intersection to move again down the street to 446 Valencia.
