Worldwide Major Earthquakes (M5+) vs US Net Migration
Worldwide Major Earthquakes (M5+) and US Net Migration correlate at r = +0.47 over 66 years (1960–2025), p < 0.0001. With the time trend removed, r = -0.15. Likely spurious (shared time trend).
Verdict: Likely spurious (shared time trend). Both series mostly just trend over time. After removing that trend the correlation collapses to -0.15 — the relationship is probably coincidental, not causal.
