The 1994 Northridge earthquake struck on January 17 and measured 6.7 on the Moment magnitude scale. It produced the largest ground motions ever recorded in an urban environment and was the first earthquake that had its hypocenter located directly under a U.S. city since the Long Beach earthquake of 1933. It caused the greatest damage in the United States since the 1906 San Francisco earthquake. Although given the name Northridge, the epicenter was located in the community of Reseda, between Arminta and Ingomar streets, just west of Reseda Boulevard. The death toll was 57, and more than 1,500 people were seriously injured. A few days after the earthquake, 9,000 homes and businesses were still without electricity; 20,000 were without gas; and more than 48,500 had little or no water. About 12,500 structures were moderately to severely damaged, which left thousands of people temporarily homeless. Of the 66,546 buildings inspected, 6 percent were severely damaged (red tagged) and 17 percent were moderately damaged (yellow tagged). In addition, damage to several major freeways serving Los Angeles choked the traffic system in the days following the earthquake. Major freeway damage occurred as far away as from the epicenter. Collapses and other severe damage forced closure of portions of 11 major roads to downtown Los Angeles.
