Abstract

A seismic zone in Goias state was described by several authors, trying to relate it with geological features, although unsuccessfully due to the lack of informations. We use here the first event with mechanism solution occurred in Porangatu in March 1991. The focal mechanism showed a 30° dextral slip fault with P axis orientation ENE -WSW. This orientation and the strike-slip motion accords to the Transbrasiliano lineaments associated to collisional process occurred during Late Proterozoic. Association with gravimetric and magnetic survey is, also analyzed.
