PERRY, Okla. – Two earthquakes recorded in less than a minute of each other rattled an area in northern Oklahoma.
The U. S. Geological Survey, says each of the earthquake was recorded Tuesday about 16 miles (27 km) west-southwest of Perry.
Geologists say 3.3 earthquake was recorded at 11:11 pm was preceded by a 2.7-magnitude temblor in the same area about 30 seconds earlier. The earthquakes were recorded at a depth of about 2 miles (3 km).
No injuries or damage reported. Geologists say damage is not likely in quakes below magnitude 4.0.
Thousands of earthquakes were recorded in Oklahoma in the past few years, with many linked to the underground injection of wastewater from oil and gas production. State regulators have directed producers to close some of the injection wells.
