On February 6th, 2023, earthquakes with magnitudes of 7.7 and 7.6 on the Richter scaleoccurred in Pazarcik/Kahramanmaras and Elbistan/Kahramanmaras/Turkey, respectively, withdepths of 9 km and 7 km and at UTC times of 01:17 and 11:24. These earthquakes causedsignificant loss of life and property in Eastern Turkey and Northern Syria. The district of Golbasiin the province of Adiyaman was one of the areas highly affected by the earthquakes due toboth the bearing capacity loss of the soil and the location of the Pazarcik Segment of theEastern Anatolian Fault Zone passing through the district center. Two days after theearthquake, the earthquake research and application center team from Dokuz Eylul Universityconducted preliminary field observations in the region. Structural damage in Golbasi wasobserved to be the result of soil-bearing capacity losses and possible liquefaction. It is knownthat the ground in Golbasi is composed of ancient lake sediments. It is considered that sitesoils in the region has caused significant soil amplification if they are highly plastic whereaslarge deformations and dependent attenuation took place in low plastic clays with silt.Therefore, it is essential to determine shear-wave velocity distribution as part of this study,microtremor measurements were taken at a total of 32 points with a 300 m sampling intervalin the Golbasi district to establish an initial database that could be easily extended by furthermeasurements to be made in intermediate locations. As a result of the microtremormeasurements, the predominant vibration period of the region, the Kg damage indexparameter, and the shear wave velocity models in 1, 2, and 3 dimensions via a forward andinverse solution of the HVSR curves were calculated, and presented. |
