Recurrent Convolutional Neural Networks help to predict location of Earthquakes

IEEE Geoscience and Remote Sensing Letters (GRSL), 2020
Abstract

We examine the applicability of modern neural network architectures to the midterm prediction of earthquakes. Our data-based classification model aims to predict if an earthquake with the magnitude above a threshold takes place at a given area of size 10×1010 \times 10 kilometers in 3030-180180 days from a given moment. Our deep neural network model has a recurrent part (LSTM) that accounts for time dependencies between earthquakes and a convolutional part that accounts for spatial dependencies. Obtained results show that neural networks-based models beat baseline feature-based models that also account for spatio-temporal dependencies between different earthquakes. For historical data on Japan earthquakes 19901990-20162016 our best model predicts earthquakes with magnitude Mc>5M_c > 5 with quality metrics ROC AUC 0.9750.975 and PR AUC 0.08900.0890, making 1.181031.18 \cdot 10^3 correct predictions, while missing 2.091032.09 \cdot 10^3 earthquakes and making 192103192 \cdot 10^3 false alarms. The baseline approach has similar ROC AUC 0.9920.992, the number of correct predictions 1.191031.19 \cdot 10^3, and missing 2.071032.07 \cdot 10^3 earthquakes, but significantly worse PR AUC 0.009110.00911, and the number of false alarms 10041031004 \cdot 10^3.
