The recording below from the broadband seismic station on the North Rim picked up the quake nicely [top arrow] and a possible minor aftershock less than 4 hours later [lower arrow]
The Google Earth image at the bottom shows the revised location (lower red squiggle) determined using the AZGS-run Arizona Broadband Seismic Network vs the original location from the USGS (upper red squiggle marked "USGS") which did not use our stations. There are also reports of the quake being felt in Havasupai Canyon.
