Descripción
In the Central Andean region of Argentina, we found gravimetric andgeomorphological evidence of an uplifting of the crystalline basement ofPie de Palo range. Within this zone, we observed a positive gravimetricanomaly in the extreme South of Pie de Palo, extending towards theSouth of Pampean ranges. By means of the geophysical technics, it waspossible to determine the magnitude and geometrical form of theanomalous body. The evidence of a tectonic uplifting is also clearlymanifested in the LandSat images, by observing the displacement of thecourse of the San Juan River towards the South. The study region is one of the major cortical and lithospheric regions with seismic activity in the country, where three of the most devastating earthquakes occurred over the last 73 years. The results would indicate that this region will continue to be one of the major seismically generating potential, significantly implying seismic dangers. The seismic risk studies indicate that the greatest hazard zone is found between the Pre-Cordillera and the Pie de Palo Range. The highest maximum acceleration values (PGA) are 242, 393, and 543 gal for return periods of 72, 475, and 2475 years, respectively.
