Geographical information system "The Earth's natural disasters Database" (ENDDB) as a tool for studying complex geotectonic structures

The software of geographical information system for studying the Earth's natural disasters (GIS-ENDDB), focused on the research into the cause- and-effect relations of catastrophic events in the history of our planet, contains data on seismic activity of the Earth, heat ows, detailed relief, and anomalies of the gravitational field as well as on the distribution of cosmogenic structures. The methods of analyzing these data are constantly being developed. All the above-said is necessary for the formulation and solution of many new geotectonic and geomorphological problems. For example, to confirm diagnostic morphological features of astroblems based on the facts (according to "Earth's impact structures Catalog"); to reveal patterns of seismogenic structures (according to seismological catalogs); to detect and to confirm structures of complex multistage Genesis such as the impact-magnetic, impact-tectonic (according to the entire range of data). Among the latest updates into the subsystems of information and mathematical software, there are functions of visualization of geophysical fields, the 3D visualization of the seismicity characteristics, and, also, the text and graphic data of geological and geophysical observations (tectonomagnetic, petrological, etc.) designed for a seismic prototype GIS-EEDB (the Expert Earthquake Database).
