Part of the Will California experience an earthquake of magnitude 6.0, 7.0, or 8.0+ by 2030? topic →
This market asks whether California will experience an earthquake of magnitude 8.0 or greater by December 31, 2030, based on USGS official magnitude reporting. The current quote of 7 reflects the UCERF3 30-year M8+ probability of 7%, prorated to the ~4.5-year window remaining through 2030 (approximately 3.3%). The hierarchical nature of the thresholds means an M8.0+ event would also resolve the M6.0+ and M7.0+ markets as YES. The June 2026 Cajon Pass stress study indicating elevated tectonic stress at the San Andreas/San Jacinto junction is consistent with long-term risk modeling already embedded in UCERF3 and does not materially change the short-term probability assessment. No external prediction markets exist for this specific earthquake magnitude question.
A moderate earthquake rattled Northern California in June 2026, part of ongoing seismic activity consistent with UCERF3 forecasts
Study finds tectonic stress on Southern California faults at highest levels in 1,000 years, with potential for joint San Andreas-San Jacinto rupture
