Shift Summary: This day has been marked by a continuing series of earthquakes. After recovering from this morning’s earthquake in Utah, the shift was dogged by earthquakes from Utah, Alaska, Indonesia, and California. We maintained lock through the day, with occasional periods of reduced range due to ground motion. The IFO is currently relocking from the Mag5.2 earthquake in Petrolia CA.
