USGS studies suggest that fracking is only rarely the cause of felt earthquakes


For the first time, new USGS maps identify potential ground-shaking hazards from both human-induced and natural earthquakes. In the past, USGS maps only identified natural earthquake hazards.

This is also the first one-year outlook for the nation’s earthquake hazards, and is a supplement to existing USGS assessments that provide a 50-year forecast

The report shows that approximately 7 million people live and work in areas of the central and eastern U.S. (CEUS) with potential for damaging shaking from induced seismicity. Within a few portions of the CEUS, the chance of damage from all types of earthquakes is similar to that of natural earthquakes in high-hazard areas of California.

“By including human-induced events, our assessment of earthquake hazards has significantly increased in parts of the U.S.,” said Mark Petersen, Chief of the USGS National Seismic Hazard Mapping Project. “This research also shows that much more of the nation faces a significant chance of having damaging earthquakes over the next year, whether natural or human-induced.”

Induced earthquakes are triggered by human activities, with wastewater disposal being the primary cause for recent events in many areas of the CEUS. Wastewater from oil and gas production operations can be disposed of by injecting it into deep underground wells, below aquifers that provide drinking water.

  1. Dr Jennifer Andrews, chemist says:

    It appears to me from reading the article that you headline is exactly contradictory to the information producd in the USGS report.
    But what can we expect from a dishonest industry promoting group like yourselves?

    • RockPick says:

      Perhaps you should re-read the whole article. If you do, you will find that the headline is taken directly from the authors text and can be found under the section titled “Explanation of Updates — Mostly, But Not All, Are Induced” – the direct quote is: “and USGS studies suggest that this process is only rarely the cause of felt earthquakes.” I would expect someone with your credentials to look at all the data before coming to a conclusion.
