Fig. 4From: Remotely assessing tephra fall building damage and vulnerability: Kelud Volcano, IndonesiaIsopachs produced from A) Tephra2 inversion and B) interpolation of manually contoured isopachs. All contours are in cm. Plots C) and D) show agreement between measured and modelled tephra loads. The grey dashed line marks perfect agreement between measured and modelled tephra loads. The solid line is the linear best fit of the data. Red dashed lines mark ±30% deviation of modelled load from measured load. Field measurement data available in Additional file 1. A dry bulk density of 1400 kg m− 2 (Maeno et al. 2019a) was used to calculate loading from thickness measurementsBack to article page
