Determination of volumetric variations and coastal changes due to historical volcanic eruptions using historical maps and remote-sensing at Deception Island (West-Antarctica)

Abstract

Deception Island is an active volcano in the South Shetland Islands (Antarctic). Its eruptions have been recorded since 1842, the last episode occurring between 1967 and 1970. This study quantifies the geomorphological changes which have taken place as a result of historical volcanic activity on the island. The linear and volumetric results obtained for the Telefon Bay and Craters of 1970s where the Surtseyan eruption took place in 1967 are presented in detail.Ministerio de Educación y Ciencia CGL2005-07589-C03- 01/ANTMinisterio de Educación y Ciencia CGL2004-21547-EMinisterio de Educación y Ciencia CGL2007-28768-E/ANTMinisterio de Educación y Ciencia CTM2009-0725
