Fig. 8

Detected event distribution without the second criterion of outlier control which rejects an envelope when the cross-correlation with the template is below the threshold, \(C_{ \lim }^{t}\), for a western Japan and b western Shikoku. The dots show the located tremor hypocenters, with the colors indicating their depths. Many of scattered hypocenters are considered as false detections. The red triangles show the Hi-net seismic stations. The inset figure in b shows a cross section of tremors located within the red rectangle
