Figure 7

Plots of length versus area, thickness, and log(volume) for observations and simulations. Plots of lava flow length versus area, thickness, and log(volume) include field observations (gray dots) and computer simulations (red points). Each plot shows results of 10 000 lava flow simulations, generated using the probability distributions shown in Figure 5 and specified in Table 3. Field observations of 20 lava flows are given in Table 1. The largest observed lava flows plot to the right of the gray line, marking > 20 km length, just beyond the range of the simulated values. These 5 flows were not considered when determining the parameter ranges for the lava flow simulations because lava flows of this length are effusion-rate limited, associated with very infrequent flank activity, and not found on the Shamiram Plateau. These results show that the volumes, thicknesses, and areal extents of nearly all observed flows fall within the ranges of the simulated values.
