Hypocenter distributions by previous studies were compared with the down-warping high-attenuation zone specified on SAP of KR101. The color scale shows percentage deviation from the mean. The lower boundaries of the hypocenter distributions of Sakai et al. (2001), the 1st observation of Nishizawa et al. (2002), 2nd observation of Nishizawa et al. (2002) and Uhira et al. (2005) are indicated as a thick chain line, a thin dashed line, a thick dashed line and a dotted line, respectively
