RIESGO SÍSMICO DE LA PROVINCIA DE TUCUMÁN: CIUDAD DE TRANCAS Y SU ÁREA DE INFLUENCIA

La Provincia de Tucumán es de “actividad sísmica moderada”, pero el grado de peligro varía según el espacio geográfico y su escala de estudio. La ciudad de Trancas esta considerada como la más peligrosa de la provincia, con actividad sísmica recurrente y registros históricos de movimientos fuertes. Este trabajo lleva al plano de la ciudad los espacios de mayor vulnerabilidad sísmica.

GEOGRAPHIC BOUNDARY AND CHARACTERS OF THE AREA OF GREATER SEISMIC RISK OF TUCUMÁN PROVINCE: CITY OF TRANCAS AND SURROUNDINGS

Abstract

The Laboratory of Structures of the UNT located to the Department of Trancas (Tucumán) in the zone of greater

danger of seismic occurrence of the province and drew up the isosist of intensity IX (modified scale of Mercalli)

for the earthquake happened in 1826 that destroyed Villa of Trancas and bordering zones. This isosist locks up a

surface approximated of 60km2 corresponding to the city of Trancas and its area of influence. The objective of

this work is to delimit and to characterize this geographic space of maximum seismic danger considering his

geographic components, that will allow to evaluate their physical, structural and socioeconomic vulnerability

forehead to the potential risk of occurrence of another similar earthquake.
