• Title: EarthquakeNPP: Benchmark Datasets for Earthquake Forecasting with Neural Point Processes
• Authors: Samuel Stockman, Daniel Lawson, Maximilian Werner,
• Abstract summary: We introduce EarthquakeNPP: a collection of benchmark datasets to facilitate testing of NPPs on earthquake data. The datasets cover a range of small to large target regions within California, dating from 1971 to 2021. In a benchmarking experiment, we compare three splits-temporal NPPs against ETAS and find that none outperform ETAS in either spatial or temporal log-likelihood.

• Abstract: Classical point process models, such as the epidemic-type aftershock sequence (ETAS) model, have been widely used for forecasting the event times and locations of earthquakes for decades. Recent advances have led to Neural Point Processes (NPPs), which promise greater flexibility and improvements over classical models. However, the currently-used benchmark dataset for NPPs does not represent an up-to-date challenge in the seismological community since it lacks a key earthquake sequence from the region and improperly splits training and testing data. Furthermore, initial earthquake forecast benchmarking lacks a comparison to state-of-the-art earthquake forecasting models typically used by the seismological community. To address these gaps, we introduce EarthquakeNPP: a collection of benchmark datasets to facilitate testing of NPPs on earthquake data, accompanied by a credible implementation of the ETAS model. The datasets cover a range of small to large target regions within California, dating from 1971 to 2021, and include different methodologies for dataset generation. In a benchmarking experiment, we compare three spatio-temporal NPPs against ETAS and find that none outperform ETAS in either spatial or temporal log-likelihood. These results indicate that current NPP implementations are not yet suitable for practical earthquake forecasting. However, EarthquakeNPP will serve as a platform for collaboration between the seismology and machine learning communities with the goal of improving earthquake predictability.
