US Coal Consumption vs Worldwide Major Earthquakes (M5+)
US Coal Consumption and Worldwide Major Earthquakes (M5+) correlate at r = +0.26 over 61 years (1965–2025), p = 0.039. With the time trend removed, r = +0.25. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.039) and the association survives trend removal (detrended r = 0.25). Correlation still isn't causation, but this one isn't an obvious artifact.
