International experience and the 2004 Olympic Games

Landslides caused by boreholes have occurred in Mediterranean countries (Spain, Italy, Cyprus and Israel) and in the USA. In the United States, this phenomenon has been the object of research studies and has lead to the application of stringent institutional measures. Already by the end of the 1960s, these problems were on the agenda of the American Society for Civil Engineering and its members have to be consulted when issuing building permits. In Greece, ground water was used properly during the runup to the Olympic Games when IGME requested an integrated drilling program for the construction requirements of Olympic projects, and 48 boreholes were opened. Scientific criteria were adhered to for the drilling of the boreholes, which were handed over to the state with clear specifications regarding their use.
