The Los Angeles Times has obtained a copy of a list compiled by researchers at the University of California of nearly 1,500 older concrete buildings across the City of Los Angeles vulnerable to collapse in the event of a major earthquake. 

Buildings on the list still need to undergo more extensive testing to determine their safety. The list only covers concrete structures in the City of Los Angeles.

Are other cities outside of Los Angeles putting together a similar catalogue of at-risk buildings?

Guests:

Mary Comerio, Professor Emeritus of Architecture, UC Berkeley; Lead scientist of the concrete buildings study

 Thalia Anagnos, Professor of Engineering, San Jose State University; Researcher of the concrete buildings study
