Evacuation zones defined for each of the CBA approaches using the spatial distribution of the absolute short-term average probability for Node 4 monitoring component weight of 0.5 for (A) P(Erup) = 0.7 and (B) P(Erup) = 1 and Node 4 monitoring component weight of 0.1 to 0.9 for (C) P(Erup) = 0.7 and (D) P(Erup) = 1 for requiring to evacuate a location from BETVHst_AVF on the day before the eruption in the Birkenhead scenario
