Fig. 10

Values of MI, CC, and MICC from 0:00 to 12:00 on 21 December 2010. The right axis shows each index after normalization by the MAD. The MAD is calculated using the half-day waveform data. The lowest panel shows the velocity waveform. The template earthquake is the earthquake shown in Fig. 2. Red lines show the threshold of detection. Green triangles in each panel show the detected events by the template using the index. White triangles show the detection using other templates. All of the events in this time window that were detected by the summed CC and MICC at station N.SUKH were identified as DLF earthquakes by visual inspection
