1. Neotectonic subdivision of Anatolia. Heavy dots indicate compressional areas, light dots indicate extensional areas. Vertical lines show complex areas within which heavy vertical lines show extensional regions, and light vertical lines show compressional regions (from Barka et al., 1995).
2. Major neotectonic structures of southwestern Turkey (from Eyidogan and Barka, 1996).

Fig. 4a

General view of trench 2 in the hanging wall of the Dinar fault. The 1995 break bounds the soil pit in the left side of the picture. Note the offset of a whitish layer in the wall perpendicular to the 1995 rupture. View from west towards east (See Fig. 2 for location).
