Seismic Imaging and Seismicity Analysis in Beijing-Tianjin-Tangshan Region
Figure 14
Cross-section of focal depth along the profile TT′ by various methods in the Tangshan area. Stars and circles show the earthquakes of ≥ 4.0 and < 4.0, respectively. (a) Distribution of focal depth by Capital Digital Seismic Network and North China Telemetry Seismic Network; (b) distribution of focal depth using local tomography with Thurber [1] method [2]; (c) distribution of focal depth using seismic tomography with Zhao et al. [3] method [4]; (d) distribution of focal depth using DD location method [5]; (e) distribution of focal depth using tomoDD method [6].
