Oklahoma rattled by shallow 5.1 magnitude earthquake

A 5.1-magnitude earthquake struck Oklahoma City at 11:24 p.m. on Friday, severely trembling the city’s residents.
The US Geological Survey (USGS) reports that the earthquake’s epicentre was situated 8 kilometres (4.9 miles) northwest of Prague, Oklahoma. The town of Prague was most severely damaged by the earthquake, and it is situated about 92 kilometres (57 miles) east of Oklahoma City.

A 5.1-magnitude earthquake strikes late at night in Oklahoma City, and aftershocks are felt.

Shawnee, Stillwater, and Tecumseh also mentioned feeling uneasy. The USGS reports that the earthquake was only 3 kilometres (1.8 miles) deep, which may have contributed to the shaking’s severity.
The USGS also discovered four further earthquakes in January near Oklahoma City, about 15 miles (24 km) northeast, with magnitudes ranging from 2.5 to 3.2. Damage usually starts at magnitude 4. A city spokesman, Bill Begley, stated that no major injuries or damage had been recorded. He also mentioned that investigators would do a detailed inspection of the infrastructure.

In a news release, Begley said: “We are in contact with state officials investigating the occurrences, as well as the Corps of Engineers, who will inspect the dam at Arcadia Lake.” The 96,000 residents of the city rely on Arcadia Lake for their drinking water.
Oklahoma saw its largest earthquake to date in September 2016, a 5.8 magnitude earthquake near Pawnee. According to Matt Skinner of the Oklahoma Corporation Commission, an investigation is underway into the earthquakes that took place at Arcadia Field.

The subterranean storage of wastewater, a waste product left over from the extraction of oil and gas, has been linked to previous earthquakes.
They stopped using the injection wells, Skinner said. “There is no oil and gas activity in that area that can be linked to these earthquakes,” he stated. Moreover, he claimed that fracking—the procedure that uses chemicals and water to extract gas and oil from rocks—does not take place there.

In Oklahoma, underground storage of wastewater from oil and gas operations has been connected to multiple earthquakes in the past few years. The corporate commission, which is in charge of the state’s oil and gas sector, has ordered several companies to either shut down their wells or retain less wastewater as a result of the earthquakes.

The earthquake was felt over much of Oklahoma, including Oklahoma City and Tulsa, as well as in Kansas, Missouri, Arkansas, and some cross-state parts of Texas, according to the U.S. Geological Survey. According to the USGS, earthquakes east of the Rockies are typically felt over larger areas, while being less frequent than those in the West. A 4.1-magnitude earthquake with a depth of 4.1 miles occurred in the Oklahoma City area in mid-January. It happened near the Northeast Edmond Gas and Oil Field on a fault line, one of several that did so.

Infrastructure is being examined; there have been no reports of significant injuries or damage.

The state has experienced a rise in earthquakes in recent years; many of them have been brought on by human activity, such as the exploitation of oil and natural gas.Late on Friday, a magnitude 5.1 earthquake with multiple aftershocks was detected in the Oklahoma City area.
The earthquake happened at 11:24 p.m. local time near Prague, about 63 miles east of Oklahoma City, according to the Oklahoma Geological Survey. Its depth was just under two kilometres.

A series of small earthquakes with a maximum magnitude of 3.5 occurred in the area.Oklahoma City and Tulsa were two of the numerous locations in the state where residents felt the trembling from the earthquake, according to preliminary estimates made public by USGS. According to the Geological Survey, the trembling was felt all the way to Wichita, Kansas.

Analysing the Earthquakes in Arcadia Field: No Relation to Oil and Gas

Shortly later, the USGS discovered minor earthquakes in the area with magnitudes of 2.6 and 3.5. Determining if the earthquakes had any effect was a slow process.The geological survey states that earthquakes in the western United States often have an equivalent magnitude but are felt over a much smaller region than earthquakes that occur east of the Rocky Mountains.

On its website, the Geological Survey said that an earthquake “can be felt over an area more than ten times larger than a similar magnitude earthquake on the west coast, east of the Rockies.”
