(Norman-AP) -- Homes and businesses in Cleveland County shook and shimmied as two minor earthquakes rocked the area.
There were no reports of damage, but plenty of people called local police yesterday to find out what was happening.
Kenneth Luza, a geologist with the Oklahoma Geological Survey in Norman, says the source of the quakes are underground fault lines that originate west of Norman.
Norman was at the epicenter of both earthquakes. Luza says the first, at 9:50 a-m, was a magnitude one-point-seven quake that probably was not felt by too many people. The second, at 1:18 p-m, was a magnitude two and was probably felt by most residents.
Neither quake was considered large enough to damage buildings or infrastructure.
