ABSTRACT
The effects of crustal movements on civil engineering systems are described based on GPS data resulting from two representative damaging earthquakes. This paper mainly discusses the displacements and strains of ground caused by the crustal movements due to the 2011 Great East Japan Earthquake to investigate the damage distribution of civil engineering structures. The distributions of the co-seismic strains agree well with the ones of damaged sites of civil engineering systems. It is concluded that co-seismic strains induced by crustal movements can damage civil engineering systems when they exceed some 10-4.5,0.000003.
