The 1994 Northridge earthquake was a magnitude of 6.7 (Mw), blind thrust earthquake that occurred on January 17, 1994, at 4:30:55 a.m. PST in the San Fernando Valley region of the County of Los Angeles. Its epicenter was in Reseda, a neighborhood in the north-central Valley. The quake had a duration of approximately 10–20 seconds, and its peak ground acceleration of 1.8g (16.7 m/s2) was the highest ever instrumentally recorded in an urban area in North America. Strong ground motion was felt as far away as Las Vegas, Nevada, about 220 miles (360 km) from the epicenter. The peak ground velocity at the Rinaldi Receiving Station was 183 cm/s, the fastest ever recorded.
