Global seismic records from the USGS show an average of roughly 16 magnitude 7.0 or greater earthquakes annually, with notable year-to-year variability driven by clustered activity along subduction zones in the Pacific Ring of Fire. Five such events have already occurred in 2026 through mid-May, including recent M7.4 shocks near Japan and Indonesia, followed by a multi-week lull with no additional M7+ detections. This pace and the inherent Poisson-like distribution of large quakes position traders to assign an 82% implied probability to reaching eight or more by June 30, while the 17% chance for exactly seven reflects uncertainty over whether the current quiet period will persist or give way to renewed activity before the resolution window closes.
