Table 3 Percentages for different nominal categories representing comparisons between scientists’ perception of local people’s views regarding the eruption impacts variables

From: Scientists’ views about lay perceptions of volcanic hazard and risk

Impact variable Locals view impact/effectiveness as greater Locals same as scientists Locals view impact/effectiveness as lower Wilcoxon T
Likely damage 17 23 49 284 p < 0.001
Likely loss of life without evacuation 16 27 58 341 p < 0.001
Necessity of temporary evacuation 7 28 65 149 p < 0.001
Necessity of permanent evacuation 11 24 66 202 p < 0.001
Effectiveness of warning plans 17 38 45 271 p < 0.001
Effectiveness of evacuation plans 19 33 48 379 p < 0.001
  1. For example, 17% of scientists thought that local people thought that the likely damage from an eruption would be greater than the scientists themselves thought.
