a year in 2015 where there were ~900 M3.0+ earthquakes against a prior tectonic background rate of just 2-3 M3.0+ earthquakes per year. During that surge in small earthquakes, 4 of the 5 largest earthquakes occurred, all greater than or equal to M5.0. These
earthquakes, widely agreed upon to be induced by wastewater injection, caused moderate but not widespread damage to the rural communities in which they occurred. I will discuss how the induced seismicity story unfolded in Oklahoma and outlook on the future.
Finally, I will discuss a hopeful roadmap to the future where scientists, industry, and regulators can work quickly to identify induced seismicity and mitigate damage to lives and property.</span><b><i><span style="font-family:Arial,sans-serif"><u></u><u></u></span></i></b></p>
