IP096: Seismic Activity and Associated Risk in Antarctica

Submitted: 28 April 2023


In 2021, ATCM Resolution 7 invited SCAR to provide a report on seismic activity in Antarctica, recognising the risks of seismic and volcanic activity for people and infrastructure, and the need to undertake monitoring and research on seismic activity and the risks associated with a high-magnitude seismic or volcanic event. This paper provides information on the causes and locations of seismic activity in Antarctica, and associated seismic hazard. It also provides an inventory of seismic stations which locate and record seismic activity, and recommends ongoing support for seismic monitoring and research. SCAR will continue to work with The Council of Managers of National Antarctic Programs (COMNAP) towards further assessment of seismic risk near Antarctic stations, noting that priority should be given to the northern Antarctic Peninsula, Bransfield Strait, South Shetland Islands and South Orkney Islands, as well as other regions with seismic clusters such as Victoria Land, Ross Island, Queen Mary Land and Adélie Land.
