LOS ANGELES (AP) - Researchers have decided to hand the city of Los Angeles a list of concrete buildings, some of which may be prone to collapse during a strong earthquake.
The Los Angeles Times says about 75 of the 1,500 buildings on the list could be destroyed during violent shaking.
The move Friday, on the 20th anniversary of the deadly Northridge quake, will help the city determine which buildings are at risk and take steps to retrofit them.
Researchers led by the University of California, Berkeley were initially reluctant to share their database because of fears of being sued by property owners.
Los Angeles officials have known about the potential dangers of concrete buildings for more than 40 years, but have not forced owners to strengthen them.
