The Oklahoma Geological Survey has shed light on the ongoing seismic activity in the metro area, attributing it to aftershocks stemming from two significant earthquakes earlier this year: a 4.4 magnitude quake near Edmond in January and a 5.1 magnitude event in Prague in February.
State seismologist Jake Walter emphasized that these aftershocks are expected to persist for several months. The agency has recorded over 2,500 aftershocks in Prague and more than 150 in the Edmond/Arcadia region. While many of these aftershocks go unnoticed by residents, the Oklahoma Geological Survey has enhanced monitoring capabilities in the Prague area, allowing for more extensive data collection.
Despite ongoing research, the cause of the initial January quake in Edmond remains a mystery. Walter noted that both fault zones have a history of activity, but further analysis is needed to understand the underlying mechanisms.
The Oklahoma Corporation Commission halted wastewater disposal into the Arbuckle formation in the Edmond area years ago in response to seismic activity. However, such disposal was permitted near Prague until the February earthquake prompted an immediate cessation request. The OCC assured that regular inspections have not uncovered any illegal operations.
The Oklahoma Geological Survey affirmed its vigilance in monitoring disposal activity and noted a decline in earthquake magnitudes and frequencies based on independent data analysis.
