Facts about the 1994 Northridge earthquake

The 1994 Northridge earthquake shook Los Angeles residents from their sleep, caused freeways to crumble and flattened buildings. It was the last deadly quake to strike a U.S. metropolitan region.

Here's a look at the toll the magnitude-6.7 quake wrought:

— Shaking lasted up to 10 seconds and was felt as far away as San Diego and Las Vegas.

— At least 57 people died and more than 9,000 were injured. Counting heart attacks, the death toll stood at 72, according to a 1995 study.

— 82,000 residential and commercial buildings were damaged or destroyed, including many apartment complexes with ground-floor parking. Some 200 steel-frame buildings suffered significant cracking.

— Seven freeway bridges collapsed and 212 others were damaged. The quake sparked fires, and affected communication, water and power systems.

— The quake caused $20 billion to $25 billion in damages.
