An earthquake measuring a 3.1 magnitude has hit outside the capital city of Ohio.
The US Geological Survey (USGS) detected the tremor 77 miles east of Columbus at 3:14pm ET.
The region sits atop an ancient fault line, a pre-existing weakness in the Earth’s crust that can be reactivated by tectonic stress, making it more prone to earthquakes.
The USGS shows ‘weak’ to ‘light’ shaking was felt around the epicenter in Cambridge.
Another earthquake hit the same around on Tuesday, also measuring a 3.1 magnitude.
An assessment from Michigan Tech University showed that people typically do not feel quakes with a magnitude of 2.5 or less.
Those from 2.5 to 5.4 are often felt but only cause minor damage.
However, no injuries or damages have been reported following Thursday’s quake.
Ohio has experienced another earthquake in that last 24 hours, measuring a 3.1 magnitude
The fault line near Cambridge is known as the Burning Springs-Cambridge fault zone that formed more than 4.6 million years ago.
The 31-foot fault extends from West Virginia through eastern Ohio.
The USGS shows Thursday’s quake hit at a shallow depth of two miles.
The shallower an earthquake, the more damage it can produce at the surface.
The 3.1 magnitude earthquake that hit on April 22 was centered about 1.2 miles southeast of Pleasant City in Noble County and occurred at a depth of three miles.
No injuries or damages were reported.
Ohio has experienced eight earthquakes of magnitudes above 2 and up to 3.1 since the start of 2025.
The Ohio Geological Survey released a new report this week, showing the state experienced 129 earthquakes last year.
That puts the state right on par with recent years, but was slightly higher than 127 that hit in 2023 and 135 in 2022.
