Abstract

PETRINOVIC, Ivan A et al. Depósito de corriente piroclástica reciente (1963-64 AD? - 1976 AD?) del volcán Copahue (I): evidencias geológicas de campo y edad radiocarbónica. Rev. Asoc. Geol. Argent. [online]. 2014, vol.71, n.1, pp.139-142. ISSN 0004-4822.

We describe a historical pyroclastic deposit attributed to a pyroclastic density current (PDC) in the NE, E and SE flanks from the Copahue volcano. The radiocarbon dating (F = 1.3678 ±0.0075) enable to correlate this pyroclastic deposit with two possible eruption times 1963-64 AD and 1976 AD (1961 AD?). We consider its importance to assess the volcanic hazard of the Copahue volcano.

Keywords : Copahue; PDC; Volcanic hazard; Radiocarbon age.
