Abstract

The ancient city of Perge is located in the Aksu district of Antalya province. Perge is one of the most important ancient city is around the world. The first settlement in Perge began on the acropolis. The earliest findings date back to the Late Neolithic Period. In a clay tablet belonging to the period of Hittite King Tuthaliya iv, the name of the city is mentioned as Parha. Perge, Archaic, Classical, Hellenistic and Roman period has hosted important buildings. Hellenistic towers, gymnasium (palaestra), theater, stadion, agora (macellum), south and north baths are examples of monumental structures. In addition, the period of Hadrian-Antoninus, by means of Pax Romana benefited greatly, can be considered the most brillant period of the city. On the margins of the acropolis, there are generally rock falls which size of 1-15 m. Breaking rocks can have a devastating effect on the archaelolgical site. Similar but more destructive rock overturns occur in the nearby Sillyon ancient city. The acropolis of Perge is geologically located on young sediments known as Quaternary Antalya travertine. In areas where mass movements such as falls and overturning occur in the Acropolis there is an Antalya Travertine (Qa) on the surface, under Kurşunlu Formation (Plk) and Yenimahalle Formation (Plk) beneath this unit. Kurşunlu and Aksu streams and creeks in the region have an abrasive effect on travertines. In addition, the cemented conglomerate unit at the bottom is degraded and transported. Besides that, travertine spreading at high elevations is generally cracked, hollow and permeable. Therefore, precipitation and surface waters infiltrate into this unit and degraded the conglomerate under the travertine. Under these effects, the conglomerate unit whose cement is disintegrated and whose strenght is weakened is subjected to defeat by the effect of vertical stress applied by the upper travertine mass and as a result, collapses, tipping and falling type mass movement occur in travertine mass. In addition to this, it can be thought that earthquakes have a triggering effect on the mass movements in the Acropolis of Perge.
