US Coal Consumption vs Worldwide Strong Earthquakes (M6+)
US Coal Consumption and Worldwide Strong Earthquakes (M6+) correlate at r = +0.47 over 61 years (1965–2025), p = 1.2e-4. With the time trend removed, r = +0.47. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 1.2e-4) and the association survives trend removal (detrended r = 0.47). Correlation still isn't causation, but this one isn't an obvious artifact.
