In the early morning hours of January 17, 1994, the San Fernando Valley region of Los Angeles was hit by a 6.7 magnitude earthquake, known as the "Northridge earthquake". The quake killed more than 70 people and injured 9,000. Most of the fatalities were attributed to collapsed buildings, parking structures, or freeways. Striking an urban area, it was very destructive, causing $20 billion in damage.
