The USGS reports a M3.0 earthquake at 8:35 pm last night, about 22 miles (36 km) east of Kingman, Arizona. [Right, orange star marks epicenter. Red lines are active faults. Credit, USGS]
However, the Kingman seismic monitoring station run by AZGS as part of the Arizona Broadband Seismic Network, shows not only this event but two others [below - time is shown as UTC; local time is 7 hours earlier]
We are assessing whether these are all earthquakes or of some origin, including blasting.
