Table 1 Activity-damage correlation (Kendall τ, Spearman ρ, and Pearson ρ) for additional events.

Disasters are sorted in order of increasing strength of the Pearson correlation coefficient. All disasters demonstrate moderate to strong levels of statistically significant correlations (P < 0.05) [with the exception of Alaska floods (DR-4122)].
