Rockslide processes on the north slope of popocatepetl Volcano, Mexico
Abstract This paper analyses the geomorphology of the north face of Popocatepetl Volcano (5450 m). The surface of the slope was covered earlier by the northern Popocatepetl Glacier and gradually exposed during the current century. The glacier formed at the time of the last great eruption of Popocate...
