-Means Cluster for Seismicity Partitioning and Geological Structure Interpretation, with Application to the Yongshaba Mine (China)

Figure 4

Cluster results and typical variables of -Means with different cluster numbers. (a) ; (b) ; (c) ; (d) ; (e) ; (f) . The solid lines represent determined faults, while the dashed lines represent inferred faults by mine geologists. The symbols ① and ② represent two caves, and the triangles represent the location of the sensors. The statistics under (a)–(f) are the typical variables for each cluster, where is the number of seismic events, is the maximum moment magnitude, is the mean moment magnitude, is the mean S-wave to P-wave energy ratio, and is the number of events with moment magnitude >0.5.
