Abstract;The Bam earthquake of December 26, 2003 (Mw6.5) occurred around the city of Bam in southeast Iran. Because the earthquake happened early in the morning at 01:56:56 (GMT, 05:26:26 local time), most of the reported 43,100 victims were killed in their dwellings. In Iran, there are dense strong ground motion networks for describing the seismological features of earthquakes, but very sparse networks for damage distribution analysis. Actually, damage differed from street block to street block, and only one seismometer was available in the city. Measuring traces of intense shakes remaining in structures, which are seen everywhere and have common features, can be very effective. The authors used utility poles in Bam for this structure. This report provides a spatial distribution of strains induced in these poles, and compares them with damage distribution in the city. (author abst.)
