The Instituto Nicaragüense de Estudios Territoriales (INETER) presents this Annual Catalogue, "Sismos and Volcanes de Nicaragua, 2005" 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.
Department of INETER has the principal responsibility to monitoring and early
warning the seismic, volcanic and geologic phenomena in
The most important
geologic event in 2005, was the earthquake which occurred, on August 3, beneath
Other important events reported in this catalog, are the volcanic explosions which occurred from July to November at Concepcion volcano, lahars at Concepcion volcano in May, several small explosions in the volcano San Cristobal in November and December, a strong seismic event occurring in August in the Pacific Ocean in front off El Astillero, and small explosions at Masaya volcano which occurred in December.
There is included information on other seismic events, earthquakes, seismicity in form of seismic swarms occurring on inhabited areas and events felt by the population mainly in the Pacific Region.
The seismic and
volcanic surveillance of the Nicaraguan active volcanoes was guaranteed during

sites. The surveillance was intensified at

In 2005, the Geophysical Department worked intensely in 13 investigation and development projects, the activities and results of which are summarized shortly in this catalogue.
