CHEROKEE, Oklahoma — Three earthquakes have rattled parts of Oklahoma near the site of last week's 4.7 magnitude temblor.
The U.S. Geological Survey says earthquakes of 4.4, 3.5 and 3.0 magnitudes were recorded Monday afternoon near the town of Cherokee. There were no immediate reports of damage.
Last Thursday, a magnitude 4.7 quake near that town shook parts of northern Oklahoma and southern Kansas.
In response to last week's quake, the Oklahoma Corporation Commission's oil and gas division released a plan calling for changes to oil and gas wastewater disposal wells in the area near the towns of Cherokee and Carmen.
Geologists have said some earthquakes are likely triggered by the injection of wastewater from oil and natural gas operations.
