• A great many buildings were severely damaged or collapsed during the earthquake that struck the northwestern part of Iran on June 22, 2002. We investigated the damage done to buildings and carried out microtremor measurements. Adobe buildings were completely destroyed or suffered heavy damage. Un-reinforced masonry (URM) structures commonly were damaged because of poor construction of their bearing walls. Absence of a lateral resistance system was one cause of failure of semi-steel structures. To examine the ground surface and structural seismic response characteristics in the stricken area, microtremor measurements were conducted on the ground surface in several locations in Abdareh Village, in which almost 100% of the adobe dwellings were completely destroyed, and on an adobe house in Tablashkin Village. A Fourier analysis, based on the H/V spectral ratio, was made to explore the relationship between the strong ground motion of the earthquake and the damage done which may have been affected by local site conditions. Building damage could be explained by the good compatibility between ground microtremor findings and the dynamic characteristics of adobe buildings which collapsed in many places but survived in part of Abdareh.
