Worldwide Strong Earthquakes (M6+) vs US Unemployment Rate

Worldwide Strong Earthquakes (M6+) and US Unemployment Rate correlate at r = +0.36 over 35 years (1991–2025), p = 0.033. With the time trend removed, r = +0.32. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 0.033) and the association survives trend removal (detrended r = 0.32). Correlation still isn't causation, but this one isn't an obvious artifact.
