Seismologists have made a significant breakthrough in earthquake forecasting with the development of a new deep learning model. The Recurrent Earthquake foreCAST (RECAST) model, created by researchers at the University of California, Santa Cruz and the Technical University of Munich, outperforms existing models in accurately predicting aftershocks.
For over three decades, earthquake forecasting models have remained largely unchanged, struggling to handle the vast amounts of seismic data available today. The RECAST model addresses this limitation by using deep learning techniques to analyze and interpret the data. Compared to the older Epidemic Type Aftershock Sequence (ETAS) model, the RECAST model is more flexible and scalable, making it better suited for earthquake catalogs with tens of thousands of events.
“The ETAS model approach was designed for the observations that we had in the 80s and 90s when we were trying to build reliable forecasts based on very few observations,” explained lead author Kelian Dascher-Cousineau. However, with advancements in technology, earthquake catalogs have become much larger and more detailed, requiring more sophisticated models.
The RECAST model not only outperformed the ETAS model but also demonstrated its ability to handle larger datasets more efficiently. Additionally, its adaptability allows for the incorporation of information from multiple regions, enabling better forecasts for poorly studied areas.
While machine learning has been explored for earthquake forecasting in the past, recent advancements have made it more accurate and adaptable for real-world applications. The computational power and time efficiency of deep learning models make them a promising tool for improving earthquake prediction capabilities.
