Opportunities and Challenges for Machine Learning Applications in Seismology
Owing to the increase in the availability of large amounts of high-quality open source data, in recent years, we observed a successful surge in Machine Learning (ML) applications in Seismology. For instance, ML has largely been adopted in earthquake detection & seismic phase picking, in generating high-resolution earthquake catalogs, in discrimination and classification of seismic events, in earthquake early warning, in seismicity forecasting, in ground motion modeling and simulation, as well as in seismic inversion. Today, traditional ML techniques, such as CNN and LSTM networks trained over very large datasets, are successfully employed in operational conditions. Nonetheless, efficient training with small and imbalanced datasets, as well as extrapolation to new data are among the challenges that are still unresolved. On one hand, advanced ML techniques such as attention layers, autoencoders and transformers provide accurate and faster alternatives. On the other hand, physics-informed learning attempts to solve the mathematical problem using neural networks or kernel based approaches, nourished by real world data. Moreover, ML techniques are adopted to improve existing predictive tools, in a non-intrusive way. However, a thorough investigation of those data-driven techniques is demanded, in both existing and new research branches of seismology, before their deployment as operational models.

In this session, we invite contributions that explore the potential of ML for seismology. In particular, we are interested in studies focusing on developing state-of-the-art ML models for seismology and earthquake engineering, ML investigations of new research areas, and works highlighting issues related to methodologies in ML, data quantity and quality. Furthermore, we welcome contributions on research topics including null hypothesis testing, open databases for collaborative research, architecture & framework, software packages and development of research capabilities.
