abstract: In Europe and elsewhere the economically feasible water resources have been greatly developed until the 1970s. 
Although large dams belong to the first structures, which have been designed systematically against earthquakes 
since the 1930s, the seismic safety of these dams is unknown, as most of them have been designed using seismic 
design criteria and methods of analysis that are considered obsolete today. The fact that no major dams have 
failed during earthquakes and that few lives have been lost (except in the case of tailings dam failures) may give 
the impression that well-designed dams are safe against earthquakes. We need to re-evaluate the seismic safety 
of  existing  dams  based  on  current  state-of-the-art  practice  and  rehabilitate  existing  dams  if  necessary. 
Additionally,  there  are  a  large  number  of  smaller  dams,  especially  earth  structures,  which  were  built  for 
irrigation or water supply by organisations or villagers with little experience in dam construction.  Earthquake 
effects on these dams have rarely been considered.
