Abstract

In this study, located in east of Turkey, for Lake Van basin proposed for the peak ground acceleration (PGA) dependent on, describes the attenuation relationships. Earthquake records in and around Van Lake Basin were used in this study. This data is obtained from Turkey. These are the acceleration records taken by Strong Ground Motion Recording Stations under the control of Republic of Turkey Prime Ministry Disaster and Emergency Management Authority Presidential of Earthquake Department. Accelerometer records of earthquakes occurred between 01 January 1976 and 31 December 2018 were compiled. For this purpose, earthquakes occurred in an area of approximately 200 km radius in and around Van province were investigated. For this study, 162 accelerometer records in EW and NS direction were compiled from 249 earthquakes with magnitude 4.0≤MW and acceleration value of 10.0cm/s2 ≤ PGA. A database was created with the earthquake record files obtained. Earthquake magnitude (MW), acceleration (gal= cm/s2), distance (R-km) etc. information for multiple regression analysis were used in these files. Multiple regression analysis was performed in IBM-SPSS software.
