a: Pleiades image showing the fault trace of the HUNF within the northwestern-most part of our study area; white triangles point out the fault trace. The black frame corresponds to Figure 10b. b: Orthophotograph taken from a drone survey detailing the fault trace within offset young cones debris. The white dashed transparent line defines the fault zone (about 20 m width). Blue lines represents active drainage and abandoned drainages (dashed), the latter are offset and used with the points as piercing lines and points respectively. Note the moto-trail track more or less parallel to the fault trace perturbing the morphotectonic analysis. The black rectangle corresponds to the trench called Stubborn Beetle (SB).
