A coccidioidomycosis outbreak following the Northridge, Calif, earthquake. Most were unable to meet this deadline and only managed to achieve compliance in 2008 or 2009.[34].

Damage to wood-frame apartment houses was widespread in the San Fernando Valley and Santa Monica areas, especially to structures with soft first floor or lower-level parking garages. He likely did not realize until too late in the early morning darkness that the elevated roadway had collapsed. It presents an opportunity to examine a significant number of such buildings affected to various degrees by severe ground shaking, to document actual damage in depth, and to dispel the myths about the Faults with the highest probability of rupturing in a magnitude 6.7 (Northridge-sized) earthquake in the next 30 years. The Northridge earthquake produced the strongest ground motions ever instrumentally recorded in a North American urban setting. Damage was wide-spread: Sections of major freeways with unwrapped supports and unextended expansion joints collapsed; parking structures and office buildings with concrete framing (non-ductile) collapsed; and numerous apartment buildings suffered irreparable damage.

Damage to the system resulted in water pressure dropping to zero in some areas; this predictably affected success in fighting subsequent fires. The comparison of the seismic behavior of underground braced walls with ACI 318 design method reveals that bending moment and shear force of the walls under Northridge earthquake loads were observed to reach 2.8 and 2.7 times as large as the respective allowable limits. In response, the California Legislature created the California Earthquake Authority (CEA), which is a publicly managed but privately funded organization that offers minimal coverage.
