Ash thickness observations from Te Maari eruption (black triangle), compared to forecasts from ASHFALL and HYSPLIT. ASHFALL contours are 10 μm, 100 μm and 1 mm. Ash observations from Pardo et al. (2014), with blue for trace amounts, and other colours approximately equivalent to thicknesses of 0.25 mm (dark green), 0.5 mm (light green), 1 mm (yellow) and 2 mm (orange)
