4.2-magnitude earthquake strikes Oklahoma, the state’s biggest in 2021

Story at a glance

  • Amid winter storm Uri, Oklahoma was hit with a 4.2-magnitude earthquake.
  • The state saw a maximum of 6 inches of snow this week.

A 4.2-magnitude earthquake struck Oklahoma on Friday, according to reports by the U.S. Geological Survey (USGS). 

The quake struck 6 kilometers, or roughly 3.7 miles, away from the town of Manchester. Since Manchester sits close to the Kansas-Oklahoma state line, tremors radiated over state lines, affecting the southwestern most region of Wichita. 

Officials report that the quake occurred at 7:56 am CST. No injuries or damage have been reported.

The depth of the quake was 7 kilometers below the Earth’s surface. Local outlets report that the seismic shakes lasted around 10 seconds. 

So far, more than 1,900 people submitted responses to the USGS reporting some level of having felt the earthquake, with responses ranging from Kansas to Oklahoma. Some responses felt weak tremors north of Wichita past Salina and as far south as Oklahoma City. 

Oklahoma has seen scores of smaller earthquakes in 2021, with this latest 4.2-magnitude quake being the strongest the state has seen this year. 

Prior to this, the state recorded a 5.8 earthquake in September 2016 — the strongest seismic event in state history. 

This latest earthquake comes at a precarious time for the Sooner State; winter storm Uri touched parts of Oklahoma, with some areas seeing up to 6 inches of snowfall, making commutes hard for drivers.

While Oklahoma hasn’t been affected as severely as its southern neighbor Texas, 175 power outages are reported across the state, potentially making it challenging for first responders and emergency services to respond to residents in need.
