Worldwide Strong Earthquakes (M6+) vs US Population
Worldwide Strong Earthquakes (M6+) and US Population correlate at r = +0.38 over 66 years (1960–2025), p = 0.0019. With the time trend removed, r = +0.11. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0019) and the association survives trend removal (detrended r = 0.11). Correlation still isn't causation, but this one isn't an obvious artifact.
