The ReFuCA project: Receiver Functions Central Andes


A set of 60 seismological stations (45 short period and 15 broadband) was installed at 21°S between the coast in Chile (70°W) and the Eastern Cordillera in Bolivia (64°W) along a 600 km long profile and operated during two years in the Central Andes region. The stations operating at a rate of 50 samples per second (sps) recorded large and local events as well as quarry blasts from the copper mines in the vicinity of the profile. The results will be used to improve the crust velocity model and to identify the Andean shear zones and their extension to the west. In addition, a shorter profile consisting of 20 stations (10 short period and 10 broadband) was installed in Argentina along a 200 km profile at 26°S with the aim to investigate lithospheric delamination across the Cerro Galan caldera, one of the most prominent intra-plate volcanoes in the world. The instruments recorded local and teleseismic events during two years and were used to map the Moho and LAB, as well as to investigate the Galan Caldera by teleseismic tomography.
