Explanation of alert calculation: Show

The impact model combines magnitude (M), population within 100km (P) and vulnerability/resilience ECHO average score (V) using the formula:
alertscore = max(M-4.5,0) * log10(max(P / 80000,0))^ 0.5 * max(V,0.5) ^ 1.5 / 3
The weighted product of magnitude (6.1), population (5007493) and vulnerability (1.75) results in an alertscore of 1.65490505240629
Then alert is Red if alertscore>2, Orange if alertscore>1 and Green if alertscore
