USGS data confirm that magnitude 10 or larger earthquakes cannot occur because no fault long enough exists on Earth to release the required energy; the scale ties directly to rupture length, and a hypothetical M10 event would need a fault spanning much of the planet. The largest instrumentally recorded quake reached only 9.5 in Chile in 1960, with subsequent M9+ events limited to subduction zones like Alaska 1964 and Sumatra 2004. Global monitoring by the USGS shows no seismic indicators or strain accumulation capable of producing such an event in the remaining months before 2027. While model uncertainties exist in long-term tectonics, the near-term probability remains negligible absent an unprecedented revision to fault mechanics.
