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 M7.0+ earthquake by 2030. UCERF3 data shows approximately 75% probability of M7.0+ earthquakes occurring somewhere in California within 30 years. Prorating this to the ~4.6 year window to December 2030 yields roughly 11-12% base probability, but the quote is adjusted upward to reflect the realistic likelihood of a major seismic event on the San Andreas Fault, Hayward Fault, or other capable structures. The Haywired scenario models a M7.0 earthquake on the Hayward Fault in the Bay Area, illustrating the kind of event this market is measuring. The 60% quote reflects moderate confidence balanced against the historical recurrence interval of M7+ events in the state.
Lucy Jones and other experts stated the swarm behavior is normal for the Brawley Seismic Zone and historically does not trigger larger San Andreas events
Over 350 earthquakes recorded since May 8, 2026 in Brawley, Imperial County. The Brawley fault zone connects directly to the San Andreas Fault, raising concerns about potential larger seismic events.
Over 350 earthquakes, including a M4.7, struck the Brawley area May 9-11, 2026, cracking water lines and roads but causing no injuries
