Table 1 Performances of three detection methods, excluding the overhead runtimes (1.5 hours of offline training for ConvNetQuake and 47 min of feature extraction and database generation for FAST).

Autocorrelation and FAST results are as reported by Yoon et al. (11). The computational runtimes are for the analysis of 1 week of continuous waveform data. NA, not applicable.
