Without studying the specifics of the wastewater injection and oil and gas production in this area, the USGS cannot currently conclude whether or not this particular earthquake was caused by industrial-related, human activities. However, we do know that many earthquakes in Oklahoma have been triggered by wastewater fluid injection. The USGS will continue to process seismic data in the following days and weeks that will help answer this question.
