Fig. 2From: Focal mechanisms and stress field in the Atotsugawa fault area, central Honshu, JapanP-wave velocity structure used for hypocenter location in the study area. Solid line indicates the structure used for the routine hypocenter determination at Kamitakara Seismic Observatory, Kyoto University (Ito and Wada, 2002). Broken line indicates the structure based on an explosion experiment (Iidaka et al., 2003).Back to article page
