SUMMARY
Western Anatolia is one of the most active regions in the world and is represented by
horsts and grabens faulted on the margins. The subject of this work, the Büyük
Menderes graben, is one of the most active structures in the region and extends between
the Aegean Sea in the west and the Denizli Basin in the east. Detailed mapping shows
that the active faults bounding the northern boundary of the graben were ruptured with
surface breaks in historical periods. These ruptures identified in detail during the field
studies. Where direct observations were not possible, however, the characteristic
features of the faults were identified by using the Ground Penetrating Radar (GPR), one
of the shallow geophysical methods.

The GPR method works on the basis of recording of the reflections of the
electromagnetic waves from the interfaces by a horizontal receiver which were
transmitted to the ground with high velocity by using a horizontal antenna. Data
collected is filtered to eliminate the environmental and instrumental noise by using
computers and then interpreted to determine the buried structures in high resolution and
sensitivity.

In scope of the investigation, GPR studies were conducted in six different locations
(two trenches, three faulted archaeological site and a buried archaeological site). The
trace of the fault, width of the fault zone and the amount of the offset of the young units
along the fault were determined by the GPR method before the excavation of the
trenches. In the archaeological site where the offset remnants of the archaeological
objects were observed, the trace of the faults and the width of the deformational zones
were determined by the GPR and the amount of offset obtained from GPR profiles were
compared with the offset amounts measured on the surface. In order to locate the exact
location of the ancient road entering the ancient Nysa town GPR, studies were
conducted and a previously unknown temple was discovered.

In the trenches which were excavated based on the GPR findings, it was found that the
amount of the offset obtained by the GPR method and the actual offset measured on the
trench wall were agreeable with each other. Where the offset archaeological structures
exist, it was observed that the faults on the GPR profiles correspond to the ruptures on
these structures. In Nysa ancient town, the image obtained from GPR was interpreted to
belong to a structure rather than the road expected; in fact, the excavations conducted
later on revealed a temple which was not known to exist before.


Key Words: Ground Penetrating Radar (GPR), Büyük Menderes graben, buried
structure, active fault.
