Taming the Seismicity Tsunami with a Scalable Bayesian Framework

These images show where earthquakes happened during the Noto Peninsula swarm in Japan. Maps (a) and (c) use a standard existing method (GrowClust), while maps (b) and (d) show the results from the new tool, SPIDER. The side-view (cross-section) only displays earthquakes that occurred within 2.5 kilometers (about 1.5 miles) of the purple line on the map. Credit: Ross et al. [2026], Figure 6
