About This Plot

The above plot shows known earthquake faults and historical earthquake locations in and around the state of Arizona.

The known earthquake faults were extracted from The US Geological Survey database of Quaternary Faults and Folds.

Historical earthquakes prior to May 2011 were extracted from Seismicity within Arizona during the Deployment of the EarthScope USArray Transportable Array by Jeffrey S. Lockridge, Matthew J. Fouch, and J Ramón Arrowsmith.
Earthquakes after May 2011 were extracted from the USGS ANSS earthquake catalog.
This plot is generated weekly to add any new earthquake locations.
