USGS assessments establish that magnitude 10.0 or larger earthquakes cannot occur, as no known fault on Earth is long enough to release the required energy—roughly 30 times that of the record 9.5 Valdivia event in 1960. Seismic monitoring through 2026 shows continued adherence to historical maxima near 9.5–9.2 on subduction zones, with no observed shifts in tectonic strain accumulation or fault geometry that could enable such an event before 2027. Trader consensus at 99.4% for "No" aligns with this physical limit and the absence of precursors in global catalogs. While model revisions or undetected deep crustal processes remain theoretically possible, current data from agencies like the USGS indicate negligible likelihood of altering the outcome in the remaining months.
