Most of the engineered buildings in Dinar were located on the flat part on river-born sediments. The rest were located toward the hills where the buildings rested on better soil. The damage in Dinar is estimated to be very great for such a small area. In the higher parts of Dinar, where the foundations were on the bedrock, the effects of the earthquake on the buildings were small or non-existent. Here the buildings, their chimneys, and the minarets were untouched.
Damage reaches a peak in the center of the city and then starts to decrease.
The last phenomena occur on thick alluvial deposits. Although the major damage was confined to the town of Dinar, there was some damage in the villages and small towns in the surrounding area. However, this damage was mostly light to medium and it rapidly attenuates with distance from Dinar. Figure 4 - Collapse of a weak upper story. The building structures in Dinar range from one to five stories.
