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 6.0 or greater by December 31, 2030, based on USGS official magnitude reporting. The current quote of 94 reflects the high probability derived from UCERF3 data, which shows a 97-100% chance of M6.7+ earthquakes in 30 years statewide. Prorating to the ~4.5-year window remaining through 2030 yields approximately 99.6%+ probability. The June 2026 seismic activity (M5.7, M5.1, M5.6 earthquakes) and the Cajon Pass stress study indicating elevated tectonic stress are consistent with background seismicity and do not materially alter the near-certain probability assessment. No external prediction markets exist for this specific earthquake magnitude question, so the quote is anchored to UCERF3 scientific consensus.
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
Study by University of Bern researchers published in Journal of Geophysical Research: Solid Earth finds stress at Cajon Pass is highest in 1,000 years
Two moderate earthquakes struck California in June 2026, continuing the pattern of background seismicity consistent with UCERF3 forecasts.
