The Nicaraguan Institute of Territorial Studies (INETER) continues with the Annual Catalogue, "Earthquakes and Volcanoes of Nicaragua, 2004" the tradition to inform in summarized form on the seismic and volcanic activity, the geological phenomena in Nicaragua, the development of the monitoring network and on our research projects. The content is based on the monthly bulletins that the Geophysical Department of INETER publishes regularly.
Geophysical Department of INETER has the principal responsibility to monitor
the seismic, volcanic and geologic phenomena in
The most important natural events observed by the Geophysical Department in 2004 and reported in this catalogue occurred in January and February (seismic activity of the Cerro Negro volcano), May (lahar at the Concepcion volcano), October (seismic event with ML=6.8 in front off El Astillero), November (seismicity in the Momotombo volcano) and December (magnitude 9.0 earthquake generates disastrous tsunami in Indonesia).
Included is information about other seismic events, about swarm seismicity and on the seismic events felt by the population, mainly in the Pacific Region of Nicaragua.
In 2004, INETER intensified
the seismic and volcanic surveillance of the active volcanoes in
