Recurrent Convolutional Neural Networks help to predict location of Earthquakes

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.
