Deficit

A layer with geological faults in Sofia and its surroundings. The faults are lines on which the earth's layers are dislocated and are directly linked to the seismic activity of the area. For each fault in the set is marked its type of active fault as well as its geologic age (the period in which it was active), and for some of the objects and vertical amplitude of the displacement in meters, although this field is not filled everywhere. Sofia falls into seismically active zone and the presence of active faults is among the main factors for assessing seismic risk in the city. Therefore, the layer is important for spatial planning, for setting construction requirements in different parts of the territory, for assessing the risk of investment intentions, as well as for engineering and seismological research. The data is current as of 01.01.2009.
