We had aftershocks on Wednesday from both of last year's more prominent earthquakes in Arizona.
A magnitude 2.5 quake (orange dot on AZ-NM border) is likely an aftershock to last June's M=5.3 Duncan earthquake. It occurred at 3:50 p.m. local time on January 28. The yellow dot is another aftershock, M=3.4 that occurred earlier in the week.
Another magnitude 2.5 quake hit south of Flagstaff, at 9:33 a.m. the same day, an aftershock to the November 30, -M=4.7 earthquake that occurred in Oak Creek Canyon near the Kachina Village area between Flagstaff and Sedona. Our calculated located is a few miles west of the USGS location (yellow dot). We think ours is the more accurate location because we are using the stations in the AZGS and NAU networks for the epicenter solution.
