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

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.

► Geomorphological changes have taken place on volcanic Deception Island. ► 1956–2003: study of volume and shoreline in the Telefon Bay and Craters of 1970s. ►1956–2003: study of volume and shoreline for the whole Island. ►1829–2003: study of inner shoreline (Port Foster). ►The tendency of volume is positive and inner shoreline contracted since 1829.
