A look at how buildings fared in a 2006 study. About RVS scores: An RVS score of 1 signals a 1-in-10 probability of collapse during a magnitude-7 earthquake. 1.4 signals a 1-in-25 probability of collapse; 2 signals a 1-in-100 probability of collapse. Engineering assessments on buildings that score 2 or less are encouraged by the Federal Emergency Management Agency.
