Fig. 9From: Estimating building vulnerability to volcanic ash fall for insurance and other purposesDamage Index – ash fall thickness relationships for four ‘experts’. The dotted lines represent the range of uncertainty (+/− 1 standard deviation) in the mean, highlighting that the greatest uncertainty exists between 800 and 1000 mm ash fall thicknesses; i.e. the range where the majority of the damage occurs (see Fig. 11)Back to article page
