This chapter gives a review of a tool for studying natural disasters, such as
earthquakes and impact events, using real data from catalogs of earthquakes
(EC) and Earth's impact structures (EISC) [1]. It is a new version of a
geoinformation system (GIS), the ENDDB (the Earth's Natural Disasters
DataBase [2]), which combines two earlier systems: GIS EEDB [3, 24] and
EISC [6]. These two prototypes are described in more detail in Parts 2 and 3 of
the chapter. The methods implemented in ENDDB allow visualizing selected
parts of a current catalog on a pseudo-3D background map. With its
mathematical support, the ENDDB system can plot frequency dependences of
magnitudes or sizes (crater diameters) of events from various samples, as well
as other distributions of integrated parameters in time and space, or their
relationships with one another.
