For the second time in two weeks, a strong earthquake has rattled the northwest Oklahoma area around the Logan County town of Marshall.
The late Tuesday morning earthquake measured 3.5 magnitude and had an epicenter about two and a half miles southwest of the town which would put it in Kingfisher County. The depth was more than a mile.
The quake hit in the STACK oil play where oil and gas development has been aggressive in the past two years. No damage or injuries were reported and it is unclear whether state regulators might ask for reductions in wastewater injection wells that could be in the region.
It was not the first quake to rattle the Marshall area. In late December, a 3.3 magnitude quake struck too. In February of 2017, a 3.2 magnitude quake was recorded around the community.
