Over the past few decades, earthquake en.i.0}eri.0} research mai.0}y focused on.the effects of stron. sei.mi. shaki.0}. After the 1999 earthquakes i.0}Turkey an.

The presen. paper （Part Ⅰ） focuses on.the effects of faulti.0} i.0}the absen.e of a structure （i.e., i.0}the free-fi.ld）. The semi.an.lyti.al approach compri.es two-steps： the fi.st deals wi.h the rupture path an. the esti.ati.n.of the locati.n.of fault outcroppi.0}, an. the secon. wi.h the tecton.cally- i.0}uced di.placemen. profi.e at the groun. surface. i.0}both cases, si.ple mechan.cal an.logues are used to deri.e si.pli.i.d semi.an.lyti.al expressi.n..
