| Description: | The BANJO and SEDA arrays were deployed as a passive source, broadband, seismic experiment in the central Andean Cordillera of Bolivia and northern Chile. This is an international [multi-institutional] project with participants from the University of Arizona, Carnegie Institution of Washington, and Lawrence Livermore National Laboratory in the U.S.A, San Calixto Observatory and the University of Bolivia in La Paz, Bolivia, the University of Chile in Santiago, and ORSTROM, a French research organization. Our scientific objectives are to extend our understanding of the deep structure and tectonics of the central Andean Cordillera and in particular the high Altiplano plateau. Our passive source experiment consisted of an east-west transect called the BANJO (Broadband ANdean JOint) Experiment and a north-south transect called the SEDA (Seismic Exploration of the Deep Altiplano) Experiment. The equipment for the east-west transect was provided by the PASSCAL program of IRIS (Incorporated Research Institutions for Seismology) and the Carnegie Institution of Washington (USA). The equipment for the north-south transect was provided by Lawrence Livermore National Laboratory (USA). The SEDA experiment consisted of seven stations deployed in a north-south transect along the the spine of the Altiplano, between La Paz and Uyuni, Bolivia. The north-south transect was about 300 km long with a station spacing of approximately 50 km. These stations consisted of Guralp CMB-3ESP and 40T sensors and Reftek (16 bit) digital recorders and were deployed from April 1994 to June 1995. |
