Natural Hazards Mitigation PlanCity of Glendale, CaliforniaSection 6 – Earthquakeshave the tools to predict where, when, and how a fault will break, and HAZUS does not considerthese issues in the loss estimation analysis.Building Damage - HAZUS estimates that between approximately 350 and 5,000 buildingswill be at least moderately damaged in response to the earthquake scenarios presented herein,with the lower number representative of damage as a result of an earthquake on the SanAndreas fault, and the higher number representing damage as a result of an earthquake oneither the Verdugo or Sierra Madre fault. These figures represent about 1 to 15 percent of thetotal number of buildings in the study area. An estimated 0 to 55 buildings will be completelydestroyed. Table 6-6 summarizes the expected damage to buildings by general occupancy type,while Table 6-7 summarizes the expected damage to buildings in Glendale, classified byconstruction type.The data presented in Tables 6-6 and 6-7 show that most of the buildings damaged will beresidential, with wood-frame structures experiencing mostly slight to moderate damage. TheVerdugo and Sierra Madre fault earthquake scenarios both have the potential to cause at leastslight damage to more than 50 percent of the residential structures in Glendale, and moderateto complete damage to as much as 16 percent of the residential stock. The distribution andseverity of the damage caused by these earthquakes to the residential buildings in the city isillustrated in Map 6.6. As mentioned before, an earthquake on the Sierra Madre fault wouldcause more damage in the northern section of the city than an earthquake on either the Verdugoor Raymond faults. The Raymond (and Hollywood) faults have the potential to cause significantdamage to the residential stock of Glendale, but the damage would not be as severe as thatcaused by either the Sierra Madre or Verdugo faults. The San Andreas fault scenario isanticipated to cause slight to moderate damage to about 10 percent of the residential buildingsin the city.2006 PAGE 6 - 43
