Deep Learning Approach for Earthquake Parameters Classification in Earthquake Early Warning System

Magnitude determination of earthquakes is a mandatory step before an earthquake early warning (EEW) system sends an alarm. Beneficiary users of EEW systems depend on how far they are located from such strong events. Therefore, determining the locations of these shakes is an important issue for the tranquility of citizens as well. In light of that, this article proposes a magnitude, location, depth, and origin time categorization using earthquake Ml magnitudes between 2 and 9. The dataset used is the fore and aftershocks of the great Tohoku earthquake of March 11, 2011, recorded by three stations from the Japanese Hi-net seismic network. The proposed algorithm depends on a convolutional neural network (CNN) which has the ability to extract significant features from waveforms that enabled the classifier to reach a robust performance in the required earthquake parameters. The classification accuracies of the suggested approach for magnitude, origin time, depth, and location are $93.67\%, 89.55\%, 92.54\%$ , and 89.50%, respectively.
