PALAEOSEISMOLOGICAL TRENCHES ACROSS THE TYRNAVOS FAULT, CENTRAL GREECE

Abstract

The Tymavos Fault (TF) is au ESE-WNW trending, north­dipping dip-slip normal fault representing one of the major tecton­ic structures bordering the Late Pleistocene-Holocene Tymavos Basin, Northern Thessaly, Greece. The fault affects Quatemary aud Pliocene deposits and mainly the Triassic crystalline limestone of the Pelagoniau basement. According to previous researches, the TF has been clearly geometrically and kinematically characterised. A well-defined fault trace has been mapped for more than 12 km, while remote sensing techniques allow to follow it further East across the northern Larissa Plain, thus giving a possible total length of almost 20 km. In this note, the results of a palaeoseismological investiga­ tion carried out along the fault will be presented and discussed.
