| 内容記述 | The three-dimensional P and S wave velocity structures of the crust of the central and western segments of the North Anatolian Fault Zone are determined by applying a tomography method to arrival times data generated by local earthquakes that occurred beneath the study area. From the obtained P and S wave velocity models, we further calculate Poisson’s ratio for a more reliable interpretation of the imaged seismic anomalies. With the exception of high-velocity anomalies detected at a depth of 8km, prominent low-velocity zones are clearly visible along most parts of the studied segment down to a depth of 25km. High Poisson’s ratio anomalies are widely distributed in most parts of the studied region. Seismic activity is more intense in the high-velocity and high Poisson’s ratio zones, although it sometimes occurs in low-velocity areas. Large crustal earthquakes occur in areas characterized by a highly heterogeneous velocity structure, but with distinctly high Poisson’s ratio anomalies. These results indicate that the active tectonics of this area are reflected in the seismic velocity structure, and that large crustal earthquakes occur generally in highly heterogeneous zones revealed by seismic tomography. These inferences are of great significance for understanding earthquake-generating processes in areas having intense seismic and tectonic activities such as the Anatolian plate. | |||||
