The Antarctic Seismographic Argentinean Italian Network (ASAIN) is a permanent broadband seismic network operating since 1995 in the Scotia Sea region, the Antarctic Peninsula and the polar area. ASAIN is managed in collaboration with the Argentinean Antarctic Institute (IAA) within the Italian (PNRA/OGS) and Argentinean (DNA/IAA) Antarctic programmes.
The Network consists of 7 broadband stations connected in real time via satellite with OGS and the IAA, and distributes real-time data to IRIS (Incorporated Research Institutions for Seismology), ORFEUS (Observatories and Research Facilities for European Seismology) and GEOFON (GEOFOrschungsNetz). The Network is a key tool for studies of regional seismicity and active seismic sources in the area, and for research into the lithospheric structure of the Scotia Sea. It also improves the detection capabilities of global seismic networks. The proximity of the seismic stations to the Antarctic continent and their continuous operation over the long term make it a privileged observatory of cryo-seisms, i.e. seismicity resulting from ice breaks, along the Antarctic peninsula.
