Figure 3

Map images used in the survey (Table 1 , Questions 14–15) showing two different types of map content. Map A depicts the hazard using a fixed ash threshold – a distribution of probabilities of reaching and exceeding a fixed ash threshold, here, 1 mm, and map B depicts the hazard using a fixed probability threshold – a distribution of ash thicknesses expected at a fixed probability threshold, here, 25%. Key in A shows binned classes of probability (e.g., 25 – 34%). Key in B shows binned classes of ash thicknesses (e.g., 1 – 10 mm). Maps were viewed at 800 × 710 pixels.
