  • Areas of high induced earthquake hazard were identified in Oklahoma
  • the hazard is higher than natural earthquakes by a factor of 3 and is similar to the chance of damage caused by natural earthquakes in parts of California.
  • Temporary seismic stations allow us to accurately pinpoint the location of the seismicity including small earthquakes that are not recorded by permanent US seismic networks.

About 25 induced earthquakes occur per year. - Drew Heimsoth https://padlet.com/montheik/83g4e04wrn1gefd7/wish/1936714026 2021-12-08 19:54:28 UTC https://padlet.com/montheik/83g4e04wrn1gefd7/wish/1936714026 Some interesting facts about induced earthquakes are that Induced seismicity can occur at significant distances from injection wells and at different depths. Earthquakes can be induced at distances of 10 miles or more away from the injection point and at significantly greater depths than the injection point. And Wells not requiring surface pressure to inject wastewater can still induce earthquakes. - Drew Heimsoth https://padlet.com/montheik/83g4e04wrn1gefd7/wish/1936714452 2021-12-08 19:54:45 UTC https://padlet.com/montheik/83g4e04wrn1gefd7/wish/1936714452 Disposal of waste fluids including oil are the number 1 reason for induced earthquakes, Induced earthquakes can occur quite far from the injection wells that cause it, Wells not requiring surface pressure can still cause earthquakes reecer06 https://padlet.com/montheik/83g4e04wrn1gefd7/wish/1936715281 2021-12-08 19:55:10 UTC https://padlet.com/montheik/83g4e04wrn1gefd7/wish/1936715281 https://padlet.com/montheik/83g4e04wrn1gefd7/wish/1936715512 3 things about earthquakes
    1.The number of earthquakes in the central U.S. has increased dramatically over the past decade. Between the years 1973–2008, there was an average of 25 earthquakes of magnitude three and larger in the central and eastern United States.

    2. Since 2009, at least 58 earthquakes of this size have occurred each year, and at least 100 earthquakes of this size every year since 2013. 

    3. The rate peaked in 2015 with 1010 M3+ earthquakes. Since 2015, earthquake rate has declined.  A.K

    Induced seismicity can occur at significant distances from injection wells and at different depths.

    Not all wastewater injection wells induce earthquakes.

    1. Recent increases in earthquake occurrence rates in Oklahoma have been linked to the injection of large volumes of saltwater, a byproduct of oil and gas extraction.
    2. The 2016 M5.8 Pawnee, Oklahoma earthquake is the largest earthquake to have been induced by wastewater disposal.

  • All  of these characteristics help us understand if the earthquakes are induced and the physical processes causing them.
  • The catalog of earthquakes generated by the temporary seismic stations provides key data for basic research to understand the mechanics of induced earthquakes.
