Hs. Akyuz et E. Altunel, Geological and archaeological evidence for post-Roman earthquake surface faulting at Cibyra, SW Turkey, GEODIN ACTA, 14(1-3), 2001, pp. 95-101
The NE-SW-trending Burdur-Fethiye fault zone is one of the major active fau
lt zones of southwestern Turkey and the ancient city of Cibyra is located o
n this zone. Segments of the Burdur-Fethiye fault zone have ruptured in the
historical period and during the 20th century. A detailed investigation in
the ancient city of Cibyra showed the presence of faults sinistrally offse
t sitting rows of the stadium up to 50 cm. In addition, there are broken co
rners of blocks, collapsed walls, broken columns, and tilted and toppled bl
ocks in existing major buildings in the city centre. Field observations sho
wed that fractures and associated damage at Cibyra were produced by a post-
Roman earthquake, possibly during the 417-A.D.-earthquake which had an inte
nsity of 9 on the MSK scale. (C) 2001 Editions scientifiques et medicales E
