Figure 7 (excerpt) – Sangay tephra fallout mean hazard maps for the combined SAV, VS, and SPL scenarios for 1 kg/m 2 threshold. The maps are produced initializing PLUME-MoM-TSM with, respectively, plume height (ph) and total volume (tv). Contour lines, where not indicated, follow the progression 1%, 5%, 10%, 50%,…

Figure 8b – Focuses on the number of earthquakes with Md > 0.5. Data are represented as red dots. Years are indicated in the labels and as black dots, marking the beginning of each year and showing the temporal evolution of the uplift. The green and blue curves indicate the two exponential…

Figure 8. Time-constrained model for brittle detachments evolution. (A) crustal thinning, hinge rolling and brittle-ductile detachment zones initiation. (B) Deformation localisation along the main brittle detachment, gouge formation and development of SC structure-dominated shear zone, coeval with the onset of ductile deformation along the upper part of the exhuming granite.
