P-wave velocity structure models for the hypocenter determination. The red dotted line and blue dotted line denote the P-wave velocity models for the preliminary location and the double-difference method, respectively. The model is derived from the refraction experiment carried out using the OBSs, an airgun array and explosives in 2008 (Nakahigashi et al., in preparation).
