The ANF Catalog of Central United States Seismicity

Abstract:

The USArray Transportable Array (TA) network, a major program within the National Science Foundation’s Earthscope Initiative, recorded numerous earthquakes in the vicinity of Oklahoma and surrounding regions that are receiving increasing attention regarding the issue of induced seismicity via hydro-fracturing and waste-water injection practices. The Array Network Facility (ANF) in San Diego employs several seismic data analysts that continuously process these events and have created an extensive catalog. Here we will present data from the ANF catalog that will include locations, magnitude ranges, depths, and time-lines for these events that may potentially include a number of anthropogenic seismic events. We will also present a visual representation of the installation footprint for the TA network in order to demonstrate the location of the TA stations with time and proximity to the suspect regions within the United States.
