The locations of the two Oak Creek Canyon earthquake aftershocks are further north than reported by the USGS. AZGS geologist Jeri Young recalculated the positions using additional stations from the AZGS-run broadband seismic network.
The yellow pins mark the USGS locations with the 5-3-15 M=2.6 event and the 5-5-15 M-3.2 event. The red circles mark the corrected locations. The large red circle marks the main shock.
The AZGS locations move both quakes, especially the M3.2 event, further north and place them along the Oak Creek Canyon fault zone, and closer to the epicenter of the main, M=4.7 shock from Nov. 2014.
