The near-certainty of a "No" outcome at 99% reflects the established geophysical limit that magnitude 10.0+ earthquakes cannot occur on Earth, as no known fault system extends far enough to release the required energy. USGS data confirm the 1960 Valdivia event at 9.5 remains the recorded maximum, consistent with subduction zone models showing realistic upper bounds near 9.6 under optimal conditions. With only months remaining before December 31, 2026, continuous global seismic monitoring by agencies like the USGS shows no activity approaching this threshold. Historical frequency data and the Gutenberg-Richter relation further underscore the absence of such events in instrumental records. While theoretically an unforeseen planetary-scale trigger like a massive impact could alter dynamics, current conditions and monitoring render any shift negligible.
