A magnitude 2.3 earthquake near Duncan Arizona, at 10:24 pm Monday night was likely another aftershock from last June's magnitude 5.3 quake. What is interesting is that this small event was felt by local residents. Typically, it takes a magnitude 3 or larger for it to be felt.
AZGS has a temporary seismometer deployed in the area, so we were able to come up with a more accurate location (red dot on photo map) than the one posted by the USGS using their regional network.
