Morphotectonics, the relation between geomorphology and (neo)tectonics is fundamental to the understanding of landscape evolution. Stressing mainly the quantitative interpretation of field observations, this monograph compares the morphological structure of drainage systems, river courses, glacial forms, volcanic landscapes and mass movements with joint orientations. The latter are indicative of the neotectonic stresses; and thus inferences on the genesis of the morphological forms can be drawn. The data on outcrops on all six continents and on islands in all major oceans have been acquired to a large extent by the author himself. The book, therefore, represents a first-hand account of the work and its relevance which has been done worldwide over the last 30 years.
