The Engadine Line (EL) is a seismically active fault in southeastern Switzerland. In the field we studied its western segment, presently not affected by seismicity but characterised by features suggesting neotectonic motions, and the coterminous Gruf Line. Uphill‐ and downhill‐facing scarps, offset rivers, non‐equilibrium hydrological conditions and aligned deep‐seated gravitational slope deformations are dominant in the weste...
