Fig. 6From: A physics-based source model for real-time tephra-dispersal forecasting for weak eruption plumesThe total SMD [kg/m] from NIKS-1D and Klawonn (2014) for the case of the Ruapehu 1996 eruption. The solid lines show the SMD from NIKS-1D. The dotted lines show the SMD from Klawonn (2014). The eruption duration for NIKS-1D is assumed as \(\sim\) 7hBack to article page
