Global distribution of eruption volumes for VEI 0 – 8 eruptions. a) Distributions obtained by maintaining separation between eruptions belonging to different VEI classes. The red and orange symbols on one side, and the blue and green symbols on the other side, refer to data with only consistent, or…

FIGURE 1. Observed (∙) vs. simulated (∘) magnitude-intensity distribution. Observed data from the LaMEVE database (Crosweller et al. 2012; Brown et al. 2014; www2.bgs.ac.uk/vogripa/, accessed in February 2019). Magnitude and intensity as in Pyle (2015), also defined in the Methods. The space of variables has been sampled through a Latin…

Figure 8. Inundation probability of small-scale PDC at the San Salvador volcanic complex derived from the systematic application of the branching energy cone model (Aravena et al., 2020a) and the vent opening probability map shown in Fig. 4. (a) Mean value. (b) 5th percentile. (c) 95th percentile. Inundation probability is…

Cotopaxi volcano. Probability density functions of conditional probabilities for (a) the next eruption and (b) the next 100 years. For each graph, it is reported on the x-axis the decision maker’s response (in %), and on the y-axis the distributions of, respectively, the Classical Model (red), the Expected Relative…

Concept of multi‐view photogrammetry draw with photos acquired during the February 18, 2005 survey. Structure from Motion (SfM) method uses a set of corresponding points between images to estimate simultaneously the 3D scene structure, the camera pose and the internal camera calibration parameters.
