Some info for you, no answers sorry.
This is a link to the Oklahoma Geological Survey Agency position statement.
“Oklahoma has long been recognized as having significant earthquake activity,
and the OGS began earthquake monitoring 40 years ago with its first seismic
station that is still in operation near Leonard, OK. Also during the 30-year
period prior to 2009 when the OGS expanded its monitoring to a network of
stations, there was an average of about 50 locatable earthquakes each year,
with only a few strong enough to be felt.
Since 2009, the earthquake activity in Oklahoma has been approximately 40
times higher than in the previous 30 years. ”
“Summary of Current Oklahoma Seismicity
The OGS has not ruled out that some earthquakes may have a relationship to oil and
gas activities such as water disposal/injection, and examining these issues remains a
major focus of ongoing research. The majority of earthquakes in Oklahoma are not
strong enough to be felt and it is important to note that an apparent spatial
correlation does not necessarily imply a causal relationship. Additionally, fluid
disposal alone is not adding enough energy into the system to materially change the
natural stresses. Overall, the majority, but not all, of the recent earthquakes appear
to be the result of natural stresses, since they are consistent with the regional
Oklahoma natural stress field”
