Summary
Geohazards are defined as processes, which potentionally or feasibly cause damages or threats. There are processes originating in relation to geological, meteorological or environmental processes in lithosphere, hydrosphere or atmosphere. Teh subject gives the students practically applicable information about individual processes threatening socio-economic development of specific area. The understanding of relation among initial factors and following negative processes affecting the area is basic in the systems analysis of those threats. Passing this subject gives the student special skills to predict and solve threats in specific area and time. It can eliminate in practice effects of geohazards.
