While making the plots below I have observed that the earthquakes have become higher in number since 2010. As you look at the magnitude the min is 0, the Max is 5.6 and the mean is 2.58. The Depth has a min of 0, a max of 56.21 and a mean of 5.16. Most earthquakes clutter over the latitude of 35 and 37 and a longitude between -98 to -96. As the histogram shows that in 2015 Oklahoma had a very large increase in earthquakes. According to an Article from Seismological Research Letters, the main culprit is wastewater disposal leading to more earthquakes due to increase fluid pressure in larger areas for periods of time.
