A permanent seismological observatory, international code TNV, is operating at MZS Italian Antarctic station: Seismological VBB data are recorded and collected according to the international SEED standard. Two independent parallel chains are running: 1) Streckeisen STS-1 Sensors + Quanterra Q330HR datalogger, marked with location code 01; 2) Streckeisen STS-2 Seismometer + Quanterra Q330HR datalogger, marked with location code 02. All data are available for the international seismological community. Research activities: global seismicity of the Earth studies; studies of local and regional seismicity; lithospheric structure studies.

The Antarctic Seismographic Argentinean Italian Network (ASAIN) is a permanent broad-band seismic network that has operated since 1995 in the Scotia Sea region, the Antarctic peninsula, and the polar area. It was deployed and is managed in the framework of cooperation between the National Institute of Oceanography and Applied Geophysics and Dirección Nacional del Antártico–Instituto Antártico Argentino and is financially supported by the Programma Nazionale di Ricerca in Antartide. The network consists of eight seismological stations with broadband sensors. ASAIN provides data to Incorporated Research Institutions for Seismology, Observatories and Research Facilities for European Seismology, and GEOFOrschungsNetz. It improves the worldwide seismic networks’ detection capabilities and contributes to refining regional earthquake locations released by the U.S. Geological Survey. The proximity of the seismic stations to the Antarctic continent and their continuous operation in the long term also allows for having a privileged observatory on the ice-related seismicity along the Antarctica peninsula.
