The Instituto Nicaragüense de Estudios Territoriales (INETER) presents this Annual Catalogue, "Sismos y Volcanes de Nicaragua, 2006" with the purpose to inform in a summarized form on the seismic, volcanic, and geologic phenomena in Nicaragua, the development of the surveillance networks and on the progress of the projects of investigation and development. The content of this catalog is based on the monthly bulletins that the Department of Geophysics publishes regularly.
