The use of the shady relief model of the ENDDB-program (the Earth's Natural Disasters Database) and the data from “Global marine gravity”, V18.1 for constructing the relief and the shaded gravity anomaly maps allows us to visually reveal the new morpho-structural elements of astroblemes or to confirm the earlier found morpho-structural regularities for numerous astroblemes. A brief review of features of an impact craters structure revealed in real data of “Catalog of the Earth's Impact structures”, presented at the ICMMG site, is given. An effort is made to estimate their reliability as diagnostic indicators. These elements are associated with the asymmetry of a crater shape manifested in a shady relief and gravity models, and are related to the meteorite body's trajectory direction.
