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.
