Description

  On December 26 2003, an earthquake of relatively moderate size - Mw = 6.6 - occurred in southern Iran. The earthquake destroyed the ancient city of Bam, killing about 26,000 people in this city and suburbs of about 140,000 inhabitants. 70% of the houses and buildings in the city collapsed, resulting in a casualty rate extraordinarily high [Zare´, 2004]. About one earthquake of magnitude similar or higher occurs every week worldwide. Why then was this particular event so destructive, resulting in one of the highest death toll in recent years? Part of the answer has to do with the location of the city near the fault itself and the structural weakness of many houses made of masonry and adobe. Nevertheless damage seems disproportionate for this magnitude earthquake. Rupture directivity has been suggested as an aggravating factor [Nakamura et al., 2005] but has not been quantified due to the poorly-known hypocentral location. We will show that the recording of the ground motion produced by the earthquake in the city itself contains some clues which help explain this disaster.
