The helicorder station at Flagstaff captured the records of the magnitude 4.7 earthquake last night between Sedona and Flagstaff and 11 aftershocks. Most occurred in the two hours following the main shock, with another around 5 a.m. this morning local time, and one after 1:30 p.m. this afternoon. More aftershocks are expected in the coming days and weeks. Thanks to Jeri Young here at AZGS for providing this record.
