Abstract
An earthquake with a magnitude of (Mw) 5.5 occurred in Yenikoy village of Acipayam district (Denizli) on 20 Mart 2019 caused heavy damages on masonary structures in Acipayam basin. Groundwater level from ground surface in the basin varies between 1m and 11m, and soil structure of the basin is made up of silty, gravely and sandy clay. Soil liquefaction was not observed in the basin after the earthquake. The main reasons of the heavy damage on the structures are mainly, high value of soil amplification, use of clayey adobe bricks and hollow bricks for building masonary houses, unpermitted construction of roof floors by using hollow bricks.
Highlights
An earthquake occurred with a magnitude of (Mw) 5.5 [1], 5.7 [2] in Yeniköy Village of Acıpayam district in Denizli city in SW Turkey at 09:34 with the local time on 20 March 2019
In the Acıpayam extensional area of the Burdur-Fethiye fault zone, magnitude 5 and above 1 earthquake occurred between years 1900 and 2019
The epicenter of this 5.3 magnitude earthquake, which occurred on 08.12.1936, is in the Uçarı district and is approximately 3 km north of the 5.5 magnitude Yeniköy earthquake, which occurred on March 20, 2019
Summary
An earthquake occurred with a magnitude of (Mw) 5.5 [1], 5.7 [2] in Yeniköy Village of Acıpayam district in Denizli city in SW Turkey at 09:34 with the local time on 20 March 2019. Fault plane solution of the earthquake given by [3] depicts that NW-SE trending a normal fault caused the earthquake (Figure 2). The earthquake was triggered by the activity of NWSE trending normal fault intersecting Acıpayam fault of the Fethiye-Burdur Fault Zone in the southeast of the basin [4]. NE-SW trending faults, bounding Burdur Lake from north and south, have left strike slip character. These faults cut through the Quaternary alluvium sediments in many locations resulting step like morphology with steep slopes. Geotechnical site investigation and evaluation of 20 March 2019 Mw 5.5 Acıpayam earthquake was performed by using and evaluating existing geological and geotechnical data, site investigation in study area after the earthquake and seismicity of the region
