Last year, a group at the U.S. Geological Survey also The magnitude 5.7 quake near Prague was preceded by a 5.0 shock and followed by thousands of aftershocks. Further research is needed but at a minimum, “there should be careful monitoring in regions where you have injection wells and protocols for stopping pumping even when small earthquakes are detected,” said Abers. Ideally, injection should be kept away from known faults and companies should be required to provide detailed records of how much fluid they are pumping underground and at what pressure, said Keranen. The Oklahoma Geological Survey has yet to issue an official account of the sequence, and wastewater injection at the site continues. Regional and national news that may include Oklahoma but not it's primary focus need to be posted elsewhere. The largest known earthquakes attributed to humans may be the two magnitude 7.0 events that shook the Gazli gas fields of Soviet Uzbekistan in 1976, followed by a third magnitude 7.0 quake eight years later.
News articles have a more stringent requirement and must be primarily focused to something occuring in Oklahoma. At this point, we are estimating that Oklahoma will hit peak demand on hospitals, ICU beds, and other critical medical supplies around April 21.”A copy of OSDH’s COVID-19 forecasting can be read by clicking Further, wellhead records showed that after 13 years of pumping at zero to low pressure, injection pressure rose more than 10-fold from 2001 to 2006, the study says. A new study in the journal Geology is the latest to tie a string of unusual earthquakes, in this case, in central Oklahoma, to the injection of wastewater deep underground. What made the swarm unusual is that wastewater had been pumped into abandoned oil wells nearby for 17 years without incident. The study authors also recommend sub-surface monitoring of fluid pressure for earthquake warning signs.

In In many of the wastewater injection cases documented so far, earthquakes followed within days or months of fluid injection starting.
“When you overpressure the fault, you reduce the stress that’s pinning the fault into place and that’s when earthquakes happen,” said study coauthor The amount of wastewater injected into the well was relatively small, yet it triggered a cascading series of tremors that led to the main shock, said study co-author Hours after the first magnitude 5.0 quake on Nov. 5, 2011, University of Oklahoma seismologist University of Oklahoma seismologist Katie Keranen (left) and Oklahoma State University geophysicist Estella Atekwana install a seismometer following a series of earlier quakes. The network's staff had felt their building shake 10 miles away so they quickly re-routed a news … The criteria is open to interpretation, but mods will have the final say if a post is approved or not. University of Memphis seismologist Stephen Horton in Wastewater injection is not the only way that people can touch off quakes. Researchers now say that the magnitude 5.7 earthquake near Prague, Okla., on Nov. 6, 2011, may also be the largest ever linked to wastewater injection. The water linked to the Prague quakes was a byproduct of oil extraction at one set of oil wells, and was pumped into another set of depleted oil wells targeted for waste storage.Scientists have linked a rising number of quakes in normally calm parts of Arkansas, Texas, Ohio and Colorado to below-ground injection. Evidence suggests that geothermal drilling, impoundment of water behind dams, enhanced oil recovery, solution salt mining and rock quarrying also can trigger seismic events. In the last four years, the number of quakes in the middle of the United States jumped 11-fold from the three decades prior, the authors of the Geology study estimate. There remain many open questions, and more scientific investigations are underway on this sequence of earthquakes and many others within the state of Oklahoma.”The risk of setting off earthquakes by injecting fluid underground has been known since at least the 1960s, when injection at the Rocky Mountain Arsenal near Denver was suspended after a quake estimated at magnitude 4.8 or greater struck nearby—the largest tied to wastewater disposal until the one near Prague, Okla. A series of similar incidents have emerged recently. In both cases, the brine and chemical-laced water has to be disposed of, often by injecting it back underground elsewhere, where it has the potential to trigger earthquakes. In contrast, the Oklahoma swarm happened years after injection began, similar to swarms at the The Wilzetta fault system remains under stress, the study’s authors say, yet regulators continue to allow injection into nearby wells. (John Leeman)The recent boom in U.S. energy production has produced massive amounts of wastewater. Kevin Stitt announced Friday, May 29.
