The 1971 Burdur earthquake struck on the morning of 12 may 1971 at 06:25 UTC (08:25 local time), with an epicenter located near Yeşilova in Burdur province, Turkey. A Surface wave magnitude of 6.1, and a body wave magnitude of 5.6 was measured. This disaster caused 57 fatalities and 150 injuries. At least 400 aftershocks were registered.[1] The total cost have been estaminated at $25 million.[2] 3227 buildings have been damaged.[5]
Geological setting[edit]
Western Turkey is one of the most seismically active regions in the world. It is experiencing an approximately north-south crustal extension. The most notable neotectonic features of western Turkey are east-west trending horst-graben and cross-graben structures, such as the Gediz graben, Büyük Menderes graben and Simav graben. A less prominent element of the region is the northeast-southwest trending basins. Some examples include the Gördes basin and the Demirci basin. The Burdur province has two of those feautures, the Burdur basin and the Acıgöl basin, both of which are half-grabens.[6][7]
The Burdur basin basin is a part of the left-lateral Fethiye-Burdur fault zone, the existence of which is disputed.[8][9]The southern end of the basin consists of the Hacılar fault and Suludere fault. The Hacılar is a 20 kilometre long northwest dipping normal fault. The Suludere fault has a right lateral strike-slip component, approximately 30 kilometre long. Both faults seperate the hanging wall with the footwall of the Burdur half-graben, along with the Burdur fault. The earthquake occured on the Hacılar fault.[7][9]
