How much time do you have?
Yeah, right...
The USGS Real Time Data site can be surfed by state, then by well site, to get the kind of graph I pulled up for Aurora, MO. A random sampling would at least show the spike, if not its magnitude or time of occurrence. I haven't tried to pull more detail out of the reports yet.
And the site numbers (I just determined with a bit more searching), are Lat & Long locations in DMS format.
