USGS data confirm that no fault on Earth is long enough to generate a magnitude 10 or greater earthquake, as magnitude scales directly with rupture length and the longest known subduction zones produce at most 9.5. The 1960 Valdivia event remains the global maximum recorded, with all subsequent large quakes falling well below this threshold. With only months remaining until 2027 and no active monitoring indicators suggesting an imminent mega-rupture, trader consensus at 98.8% for “No” aligns with these physical constraints. While an unforeseen asteroid impact could theoretically exceed this limit, such events lie far outside observed seismic patterns and would not resolve the market under standard criteria.
