FOR SEISMIC EVENT DETECTION. Part 1: ARCHITECTURE

An artificial neural network, SeisDetNet, has been developed for distinguishing seismic events from seismic noise based on waveform records. The international STEAD database, which contains minute-long records of local earthquakes and seismic noise, was used as the data source for training, validation, and testing. Specifically, we selected waveforms from 27 seismic stations located in Kyrgyzstan and surrounding areas from the KRNET, KNET, KZ, G, and TJ networks, present in the STEAD database. The model architecture is a combination of a convolutional network, designed to extract key features for class separation, and a fully connected network for the task of classifying the input record as either a seismic event or seismic noise. Evaluating the model on the test set showed good results, with the following binary classification metrics: accuracy of 0.983, precision of 0.989, recall of 0.982, and F1-score of 0.985.
