  • Washington University in St. Louis (WUSTL)
Network name Seismic Experiment in Patagonia and Antarctica (SEPA (II)) Deployment region United States of America
Start year 1999 End year 2004
Short description

5 stations were installed in Chilean Patagonia and 5 stations in the Antarctic Peninsula region. 3 of the Antarctic stations are located at Chilean bases.
