Fig. 6

Changes in detectability along the Japan Trench. The maps show the distribution of the a JMA unified catalog data and b automatically determined epicenters. The colors indicate depth. c Frequency magnitude distribution of each region. Red and black color indicate the numbers of the JMA unified catalog and automatically determined hypocenters, respectively. Mc is based on MAXC (mode value) + 0.2 (Woessner and Wiemer 2005). Region A does not include the epicenters in region D
