ShakeOut Damage to Buildings! Concrete buildings: ! Commercial buildings from 1950s and 1960s ! In highest shaking areas, 10% collapse! Biggest life loss in scenario
! Unreinforced masonry ! Collapse of 300+ buildings ! Complete financial loss for 90% within 30 km of
fault ! Pre-1994 steel frame high rises could collapse ! 300,000 buildings with loss >10% of value

Retrofitting URMs has saved lives
! In the Northridge earthquake: •No one died in a URM •Only 19% of inspected URMs needed repairs
compared to 33% of buildings overall
!Statewide•Jurisdictions have retrofitted or demolished
88% of URMs with mandatory programs •Only 22% with voluntary programs

In California, many more buildings impaired
▪ Average of Loma Prieta & Northridge ▪ For each collapse
+ 13 red tags ▪ For each red tag,
+ 3.8 yellow tags ▪ = 63 impaired per collapse
