A rash of earthquakes erupted in counties across northern and central parts of Oklahoma, Sunday night.

Five earthquakes in all were recorded between 8 p.m. and 8:30 p.m., the most of which occurred near the town of Medford, Okla.

The first earthquake was recorded four miles to the northwest of Perkins, Okla., in Payne County, at approximately 8:11 p.m. The United States Geological Survey (USGS) measured this quake as a 2.9 magnitude event.

A second earthquake rumbled, and the most active epicenter of the outbreak, was recorded at 8:18 p.m., 10 miles east, southeast of Medford, in Grant County. Then another quake struck in the same location a minute later. The USGS measured both quakes at a 2.7 magnitude on the Richter scale.

The fourth earthquake struck 16 miles to the northeast of Helena, Okla., in Alfalfa County, at approximately 8:28 p.m. According to the USGS, this earthquake was a 2.5 magnitude recorded at a depth of about seven and a half miles.

Finally, the largest temblor of the group rumbled near Medford, in the same location as its two predecessors. This earthquake, according to the USGS, weighed in at a 3.4 on the Richter scale.

So far, there have been no reports of damage or injuries associated with any of these earthquakes.

Sunday has proven to be a very seismically active day for central and northern parts of Oklahoma. Earlier in the afternoon, a 4.2 magnitude quake struck just south of Stillwater, Okla. In all, nine earthquakes have been recorded.

According to the USGS, earthquakes with magnitudes ranging from 2.5 to 3.0 are generally the smallest ones felt by humans. Damage is more likely from earthquakes at magnitudes of 4.0 and higher.
