Comment on “Geodetic investigation of the 13 May Kozani‐Grevena (Greece) Earthquake” by Clarke et al.

In a recent paper, Clarke et al. [1997] try to describe the coseismic displacement field of the 1995, Grevena (Northern Greece) earthquake by comparing triangulation surveys of a geodetic network made in 1984-1986 and a post-earthquake survey of the same network with GPS made in 1995. The composite triangulation-GPS horizontal displacement obtained and the model proposed are inconsistent with important tectonic, seismological and geodetic observations that Clarke et al. [1997] have ignored in their inversion procedure.
