Figure 3

Seismicity rate forecast for different regions, including the whole study area, central Oklahoma (longitude \(\ge -98^{\circ }\)), western Oklahoma (longitude \(<-98^{\circ }\)), Pawnee area, Prague area, and Fairview area. The gray lines are observations, and the blue and red lines are forecast results from training and test dataset, respectively. The red dashed line shows forecast for year 2020, where the injection data are not available yet. Red areas indicate one standard deviation from 100 runs. The ___location of the Pawnee, Prague, and Fairview is shown in Fig. 1. The \(R^2\) and \(R_{adj}^2\) for training data and test data are listed on each subplot. Notice that \(R_{adj}^2\) is smaller than \(R^2\), especially for Pawnee, Prague, and Fairview, where the number of data points is small.
