The Department of Geological Hazards is the successor to Department of Engineering Geology and Hydrogeology created in 1953.
The first leader was Corr. Member of BAS Prof. Boyan Kamenov. Later this department develops, as it is released through reform the Department of Engineering Geodynamics (until 2006). In the period 1978-1994, the Department is a part of the Geotechnical Laboratory of BAS, which in May 1994 transferred to the Geological Institute. Head of this Department was Academician Prof. Ilia Bruchev, under whose leadership is doing important research for the country as The Map of the Geological Hazards in Bulgaria, The Landslide Map in Bulgaria, National Strategy for Mitigation of Landslide Hazards, and others. The Department is leading in studies on the hazardous geological phenomena (landslides, rockfalls, slow fault movements, etc.) and related slope stability problems, landslide hazard maps (inventory and susceptibility mapping), database of landslides in Bulgaria, instrumentation monitoring on hazardous phenomena, soil and rock mechanics.
In the section are 1 doctor of sciences, 2 professors, 1 associate professor, 1 chief assistant, 2 PhD students and 1 technician. Head of the Department is Prof. Dr. Nikolai Dobrev.
