The South American Array (SAMARRAY) is an idea born with the objective of creating a permanent seismological network in South America, and repeatedly deploying a dense array of mobile stations.Seismological stations from EarthScope?s USARRAY (which is in its final stage) might be used to cover the continent in coordination with national seismological networks and act as a backbone network. This configuration could benefit from existing local networks and research capacities and, although it would confront some new challenges, it would benefit tremendously from logistical andtechnical lessons learned during the USARRAY project. SAMARRAY would, however, sample a great variety of new terranes and processes that would extend and complement scientific advances made as a result of USARRAY. Study of the seismicity related to the different subduction processes, as well as related crustal, and intraplate earthquakes, lithospheric structure of the cratons interacting with the subduction zones, Andes chain and subduction zones are among the main objectives. Tropical rainforest and high mountain chains constitute only some of the logistical challenges?and opportunities?for a project that requires coordination of multinational partners for potential impact for the Latin American Subduction Zone Observatory (LA-SZO).
