Fig. 5From: A step-by-step evaluation of empirical methods to quantify eruption source parameters from tephra-fall depositsClassification of Layer 5 of Cotopaxi volcano using the schemes of aPyle (1989) and bBonadonna and Costa (2013). When using Pyle (1989), one point is plotted for each isopach segment. For Layer 5, the blue and red dots are the proximal and distal segments, respectively. When using Bonadonna and Costa (2013), TephraFits plots a ±30% uncertainty on λTH and a ±50% uncertainty on λML/λTHBack to article page
