Key Points

The research aims to analyze global seismicity trends over a decade, focusing on earthquake patterns and dynamics.
Utilized USGS ComCat data for a 10-year analysis of seismic activity.
Examined earthquake patterns across eight geographic regions.
Quantified frequency-magnitude scaling using the Gutenberg-Richter law.
Analyzed temporal clustering within major seismic sequences.
Asia was identified as the primary driver of global seismic activity, with nearly 975 events in 2025.
The global b-value was recorded at 1.15, indicating a higher proportion of small-to-moderate earthquakes.
Documented multi-year activity rhythms and inter-event waiting times provide a new baseline for seismic hazard modeling.

Abstract

This research paper by Open Terra Labs provides a comprehensive 10-year analysis of global seismicity from 2016 to 2026 using USGS ComCat data. The study examines earthquake patterns across eight geographic regions, quantifying frequency-magnitude scaling through the Gutenberg-Richter law and analyzing temporal clustering within major seismic sequences. Key findings highlight Asia's role as the primary driver of global seismic activity—peaking at nearly 975 events in 2025—and identify a global b-value of 1.15, suggesting a higher proportion of small-to-moderate events than historical norms. By documenting characteristic multi-year activity rhythms and inter-event waiting times, the paper establishes an empirical baseline for contemporary seismic hazard modeling and regional monitoring priorities.
