(a) Median three component cross-correlation values on all stations for all event pairs within identified multiplets, (b) moment magnitudes of all ME and SE, (c) moment magnitudes of ME from groups A–D, (d) example of the multiplet consisting of 5 events: overlaid signals after filtration to 1–15 Hz, station HBW, 3 components, (e–g) relocated ME and distinguished ME groups (A–D).
