The U.S. Geological Survey (USGS) has issued a statement that earthquakes have become more frequent in Oklahoma and that more can be expected. They did not issue an “earthquake warning” for that area, just an advisory that more can be expected in the years to come.
The goal of the advisory is to heighten the alert of residents there to the on-going potential of earthquakes. Oklahoma has long been known as a seismic-zone where earthquakes are possible, but there has been a 50% increase in the number of these quakes since 2013.
From October 2013 to April 14th of this year, there have been 183 earthquakes rated 3.0 or higher in Oklahoma, compared to an average of fewer than 2 per year in the two decades prior to that time period.
