Erzincan havzası ve dolayının üst-kabuk hız yapısının (1-B) belirlenmesi

Bu çalışmada, Erzincan havzası ve dolayına ait 1-B P- ve S- dalgası hız yapısının bulunması amaçlanmıştır. 13 Mart 1992 Erzincan depremine (Mw=6.9) ait 1548 artsarsıntının 22250 P- ve 10184 S- varış zamanı, çözümlemeler için kullanılmıştır. Tüm veri grubu içerisinden GAP

Determination of upper_crust velocity structure (1-D) of the Erzincan basin and its surroundings

In this study, we aimed to obtain upper-crust 1-D P- and S- wave velocity structure of the Erzincan basin and its surroundings and to find accurate hypocentral parameters. 22250 P- and 10184 S- arrival times that belong to 1548 aftershocks of the March 13, 1992 Erzincan earthquake (Mw=6.9) were used for calculations. The stations that have Telemetry, Geostras, MEQ, Reftek and MLR type recorders were consist of sismometers with both vertical and tree-components. VELEST was used to calculate minimum 1-D velocity structure of the region for both P- and S- wave. A subset of all data set was prepared by selecting well locatable afterhocks have GAP
