Resumen:
Research for evaluation of geologic hazards involving earthquakes and volcanic eruptions in southern Argentina seems to have historically
received little attention. Nevertheless, the relatively small work done indicates a Neogene tectonic architecture in the area with capability
of generating potential hazardous earthquakes in a growing population region. Seismicity and some morphotectonic evidences of Quaternary
activity of the Magallanes?Fagnano left-lateral fault system in the transform boundary between South America and Scotia plates, are analysed
in this paper. This fault system is considered to be an important seismogenic source, responsible for large earthquakes that have occurred in
southern Argentina. Some examples from the South and Austral Andean Volcanic Zones are also examined in order to show recent volcanic
activity which also generated crustal seismicity. Preliminary hazard estimation clearly shows the presence of both potentially active volcanic
centres in southern Patagonia that may also trigger seismicity and the high probability for large crustal earthquake generation.
