A string of small earthquakes have been recorded this weekend in central Oklahoma.
The U.S. Geological Survey says the latest was a 3.3 magnitude quake recorded just before 8 p.m. Sunday, three miles north of Spencer, which is about 10 miles northeast of Oklahoma City.
Four others were recorded from 3:15 to 8:45 p.m. Saturday and ranged in magnitude from 2.5 to 2.7. Three were near Spencer and the fourth near Jones, about 15 miles northeast of Oklahoma City.
Those were recorded several hours after 3.6 and 3.7 magnitude quakes near the Oklahoma City suburb of Edmond and another 2.7 magnitude tremor near Jones.
Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest felt by humans and damage is not generally seen from quakes below magnitude 4.0.
