Figure 3. Coulomb 4.0’s updated desktop, with a map, Functions, Overlays and the Element Input Panel all simultaneously visible. One can toggle between Mosaic and Interpolated stress or strain. Contours can be added. The fault friction coefficient, calculation depth exaggeration can be adjusted. Whenever one inputs an earthquake source and slip, its seismic moment and magnitude (Mw) is reported in the Message panel. Credit: Temblor, CC BY-NC-ND 4.0
