SISMOS HISTÓRICOS Y RECIENTES EN MAGALLANES
Earthquakes in Magallanes, southern Chile, are associated to the relative motions (smaller than 2 cm./y) of three plates: South-American, Antarctic and Scotia. Thus, the seismicity is low as compared with northern Chile where the Nazca and South-American plates converge at a rate of about 10 cm./y....
