Schematic illustration of the ways in which tephra hazard is depicted in the maps in the survey (based on all single hazard tephra depictions n = 25). A Black solid lines with quantitative indicator (n = 5), B Solid and dashed lines (n = 8), C Patterned area (n = 1), D Single coloured area (n = 3), E Multi-colour scheme based on hazard level (n = 3), F Dark to light single colour scheme based on hazard level (n = 3). Two maps communicated that the entire area displayed on the map may be exposed to ash fall via text boxes (not depicted)
