    In this June 26, 2014 file photo, Austin Holland, research seismologist at the Oklahoma Geological Survey, hangs up a chart depicting earthquake activity at their offices at the University of Oklahoma in Norman, Okla. A study published Thursday, July 3, 2014 by the journal Science explains how just four wells forcing massive amounts of drilling wastewater into the ground are probably causing quakes in Oklahoma. The wells seem to have triggered more than 100 small-to-medium earthquakes in the past five years, according to a study.

    Two earthquakes have struck northern Oklahoma in less than 24 hours.

    The area felt a 4.0 magnitude quake Tuesday morning and a 4.3  one Monday afternoon.

    One tremblor hit Grant County, with an epicenter about three miles northeast of Medford at a depth of about 4.7 miles, according to the United States Geological Survey (USGS).

    Oklahoma, Texas and Kansas have been witnessing tens of temblors, which scientists link to hydraulic fracking and its wastewater wells in the area.

    The other was felt in Noble County, which is southeast of Medford. 

    Angela Wilson, a dispatcher in the Grant County Sheriff's office, told USA Today that she felt shaking in the Medford office but that no calls related to the quake had come in from first responders or residents.

    The USGS says the quake was felt in the Oklahoma City area and in southern Kansas.

    Fracking, or hydraulic fracturing, is the process of blasting pressurized sand and liquid (water and other chemicals) deep into the earth to extract gas and oil, a controversial process a growing number of states are using.
