Abstract

Twenty years ago very little was known about the seismic activity of the Amazon region. The low population density and the delay in the installation of seismograph stations in the region contributed to the lack of knowledge about possible earthquakes. This situation only changed in the late 70's when studies about the seismicity of the Brazilian Amazon region were initiat+ed+H308 with the progressive installation of a network of stations through co-operative agreement between the University of Brasilia and Eletronorte (Electric Plants of Northern Brazil), The number of earthquakes that have already been recorded and the known cases of reservoir induced seismicity (RIS) show that the region bears an important level of seismic activity which needs to be carefully evaluated. To improve the capability of-seismic detection in this region, which represents 60% of the national territory, a modem network of stations, named AMAZONS cope, was conceived. Its purpose is to perform a continuous seismic monitoring program. The Network installation, operation and data analysis and interpretation, will be done by the University of Brasilia (UnB) Seismological Observatory (SIS) in collaboration with Eletronorte and of the Amazonian Military Command (CMA).
