The training results: (a) the corresponding relationship between the number of epochs and the accuracy rate during the training process; (b) the model accuracy rate of earthquakes with different magnitudes; (c) part of the results. The magnitudes from left to right are 5.4, 6.1, 7.3, and 9.0, respectively. The ratio of the Arias intensity in the last 5 seconds to the previous 5 seconds is 5.2, 0.61, 0.67, and 2.17. The model predicts that the probability that the intensity of the magnitude 5.4 earthquake will increase is 99.6%, that the probability of decreasing intensity of the magnitude 6.1 earthquake is 65.6%, that the probability of decreasing intensity of the magnitude 7.3 earthquake is 58.2%, and that the probability of increasing intensity of a magnitude 9.0 earthquake is 74.0%.
