Map of the study region. The area indicated by the open rectangle was used to select LFE events from the JMA catalog. The black and red dots represent the LFE epicenters before and after relocation, respectively. The gray square shows the fault plane, which is a 16 km × 16 km square that is centered at the centroid of the relocated LFEs. The triangles indicate Hi-net stations used in this study. The inset map shows the location of the study region in western Shikoku relative to Japan
