Fig. 1From: Determining seasonal displacements of Earth’s crust in South America using observations from space-borne geodetic sensors and surface-loading modelsSouth America and its main physiographic regions, with the 292 GPS stations (green circles) used to quantify the crustal deflections due to the loadings. The numbers within the white circles are the river basins’ identifications (ID), which are associated with their individual names as follows: Amazon (01), Atrato (02), Barima (03), Bio–Bio (04), Chubut (05), Colorado (06), Corantijn (07), Essequibo (08), Gallegos (09), Grande River (10), Lagoon Mirim (11), Lauca (12), Magdalena (13), Maroni (14), Negro (15), Orinoco (16), Oyapock (17), Palena (18), Paraná (19), Parnaíba (20), Patia (21), Salgado River (22), São Francisco (23), Sinu (24), Titicaca (25), Tocantins (26), Tumbes (27), Uruguay (28), and Zarumilla (29)Back to article page
