A new kind of concrete called "SIMCON" may keep buildings earthquake proof  

(CNN) -- Seattle recently experienced a big earthquake, but suffered relatively little damage. The city's buildings shook, but did not collapse.

Scientists say building collapse is what causes most of the death and injury in quakes like the one that killed 20,000 people last August in Turkey.

Researchers at North Carolina State University found out a new kind of concrete called "simcon," which is reinforced with mats made of stainless steel fiber, that could make buildings virtually earthquake proof.

CNN's David George tells us how researchers are working to make buildings as safe as they can be from earthquakes.
