OKARCHE, Okla. — A magnitude 3.3 earthquake was recorded early Friday morning west of the Okarche-Kingfisher area.
The temblor hit at 1:34 a.m. about 9.5 miles northwest of Okarche, according to U.S. Geological Survey. It was centered about 2.49 miles deep.
It was the second earthquake measuring more than magnitude 3 in Northwest Oklahoma this week.
Wednesday evening, a magnitude 3.5 quake struck a little northeast of where Friday's quake was recorded. Wednesday's quake was about 8.8 miles west of Kingfisher, according to USGS. It was about 1.24 miles deep.
A swarm of 27 earthquakes were recorded west of Kingfisher in late July. The largest of those measured magnitude 3.8, according to USGS. Nine of the quakes in the swarm registered more than magnitude 3.0.
The swarm of quakes prompted a well site to be shut down indefinitely. Well completion work was being conducted by Encana Corp., but the company shut down operations.
According to USGS records, there have been 32 earthquakes this year measuring at least magnitude 3.0, compared to 122 recorded last year through Aug. 9, 2018.
The largest quake recorded in Oklahoma in 2019 was a magnitude 4.4 — approximately 5 miles east of Pond Creek and 9 miles south of Medford — on May 17.
