The application of HVSR microtremor survey method in Yüksekova (Hakkari) region, Eastern Turkey

• Local soil conditions of Yüksekova (Eastern Turkey) are investigated.
• Seismotectonic features of the Yüksekova region are determined.
• HVSR peak amplitude values are measured in Yüksekova settlement.
• HVSR peak period map has been prepared in the study area.
• Hillside effect of study area is found.

The horizontal to vertical spectral ratios of microtremor (HVSR) analysis of Yüksekova and its surroundings is carried out using the results of field investigations, local soil conditions and seismotectonic features of the region. Soil-structure interaction is one of the most important reason for building damage ratio. The effects of soil conditions on probably damaged building units were determined, by conducting HVSR microtremor measurements.In this study data collection is handled during 30 min using three component seismograph measurements at 40 points in the Yüksekova region. HVSR peak period map shows that the fundamental period range between 0.4 and 1.6 s in the soft sediments units. Rock sites of the northern coast of Yüksekova period range between 0.1 and 0.2 s. HVSR peak amplitude values are in the interval 1.5–6.0.
