Abstract

Turkey is the one country in which 90 of the buildings are subject to the risk of earthquake disaster Recent earthquakes revealed that Turkey’s present residential reinforcedconcrete constructions are insufficient in earthquake resistance Many of the buildings which collapsed or were severely damaged have been rehabilitated by applying simple methods whose adequacy is questionable As in Japan and the United States Turkey’s earthquake assessment studies have increased especially after earthquakes in 1999 In US several methodologies and standards such as HazardUS HAZUS and Applied Technology Council ATC 132021 and 156 provide comprehensive earthquake loss estimation methodology for postearthquake assessment This paper provides postearthquake assessment and disaster management for Turkey The main aim of the postearthquake assessment discussed is to evaluate loss and estimate damage through disaster management approach Classification criteria for damage are essential to determine the situation after an earthquake in both the short and long terms The methodology includes probabilisticbased analysis which considers the magnitude of Ms ≥ 50 earthquakes between 1900 and 2005 for determining the probabilistic seismic hazard for Turkey
