Worldwide Major Earthquakes (M5+) vs Worldwide Strong Earthquakes (M6+)
Worldwide Major Earthquakes (M5+) and Worldwide Strong Earthquakes (M6+) correlate at r = +0.39 over 66 years (1960–2025), p = 0.0012. With the time trend removed, r = +0.20. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0012) and the association survives trend removal (detrended r = 0.20). Correlation still isn't causation, but this one isn't an obvious artifact.
