Worldwide Strong Earthquakes (M6+) vs US GDP per Capita
Worldwide Strong Earthquakes (M6+) and US GDP per Capita correlate at r = +0.31 over 66 years (1960–2025), p = 0.011. With the time trend removed, r = -0.22. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.011) and the association survives trend removal (detrended r = -0.22). Correlation still isn't causation, but this one isn't an obvious artifact.
