Worldwide Strong Earthquakes (M6+) vs US Imports
Worldwide Strong Earthquakes (M6+) and US Imports correlate at r = +0.44 over 55 years (1970–2024), p = 8.4e-4. With the time trend removed, r = +0.30. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 8.4e-4) and the association survives trend removal (detrended r = 0.30). Correlation still isn't causation, but this one isn't an obvious artifact.
