| Summary: | Globally there has been a marked increase in both the frequency and cost of natural disasters occurring due to geological, hydrological and meteorological causes. According to the United States National Academy of Sciences losses caused by natural disasters have quadrupled in the last twenty years. This book, conceived as a technical manual deals with various aspects of geohazards - using photogeology and remote sensing. It is unique in that the succinct text supports the illustrations, and is aimed at geoscience professionals and university students, devised as a quick-reference standardized presentation of 177 globally occurring photo-geomorphological units and an equal number of variants derived from a comprehensive image-resolvable and ordered genetic classification of geounits. The selected geounits are uniquely classed and identified as either agents of, or susceptible to, one or more of the 14 general types of geohazards. The data set of each geounit systematically integrates characterizing graphics, ground- and air- perspective photos to introduce interpreted aerospace mono/stereoscopic photos and images demonstrating their detectability and mappability
