Abstract

The earthquake of Adana (Southern Turkey) took place on 27 June 1998. Its epicenter lays close to the city and its magnitude was M^6.2, sufficient to cause a large number of deaths and extensive damage to human constructions. This motion resulted by a left lateral strike-slip faulting along the NE-trending East Anatolian fault system and other fault zones, parallel to it, in the west. The earthquake focal mechanism solution is in agreement with this tectonic setting. In Adana, mainly older constructions bore the brunt of damage, though newer; multi-story buildings did not escape unharmed. In Ceyhan, extensive damage was spread, even to new constructions, while multi-story buildings were largely destroyed. In Ceyhan, specific types of failure were observed; they were due to construction type, building shape and azimuth
