There has been a lot of excitement in the past few
years about the rather sudden appearance of
a large number of earthquakes in a region that one would expect to be quiet,
Several studies suggest that these earthquakes have a human origin: deep
injection of waste water
from the fracking process lubricating ancient faults.

The oil industry is very important to the economy of
Oklahoma. The following view represents the
location of approximately 25,000 well sites that still had equipment located at
the site. I visually located
and identified each individual well site. Well sites that had been
abandoned and the equipment removed
were not included this map.
There were so many locations that the marking icons
I recorded earthquake epicenters in Oklahoma from
October 2012 to January 2016 on a daily basis.
The information was reported on the USGS website for earthquakes for the past
week. There are
approximately 2500 earthquake epicenters indicated on the following map.
During most of the time
period from 2012 to 1216, Oklahoma was the most active earthquake zone in the
U.S., even more active
happens when the wells and epicenters are posted on the same map? There is
but there are areas with only wells and no earthquakes, but there are areas with
many earthquakes and
few wells in the same vicinity. Because of the high density of wells and
earthquakes, it is difficult to see
the details of the pattern.
I love seeing actual data in order to draw my own
conclusions. Consequently, I am presenting the oil
well and earthquake data on a county by county basis.
