Worldwide Strong Earthquakes (M6+) vs US Net Migration
Worldwide Strong Earthquakes (M6+) and US Net Migration correlate at r = +0.43 over 66 years (1960–2025), p = 2.6e-4. With the time trend removed, r = +0.25. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 2.6e-4) and the association survives trend removal (detrended r = 0.25). Correlation still isn't causation, but this one isn't an obvious artifact.
