National Seismological Centre (NSC), Nepal
Main Objectives
- Operation of seismological network, record both local and distant earthquakes, localization of recorded earthquakes and their interpretation.
- Determination of hypocentral (latitude, longitude, depth and originated time) parameters of local earthquakes with magnitude greater than 4 magnitudes in time (within one hour in office hours) and its release to home ministry and local media (Radio Nepal, NTV etc.)
- Intensity mapping of medium (M<7) to large earthquakes (M>7) and assessment of damage.
- Study of seismotectonics of the Nepal Himalaya based on the seismic data collected from the 20 seismic stations of the National Seismological Network.
- Preparation of epicenter map and seismic hazard map from the collected data and other geological and geophysical data/information.
- Distribution of seismic data to agencies involved in infrastructure development and researchers upon official request.
- Operation of 13 Continuous Global Positioning System (GPS) stations to study crustal deformation, which may closely monitor tectonic movement of tectonic plates and displacement on faults before, during and after earthquake generation.
- Seismic microzonation of Urban Areas.
- Organize public awareness programs / campaign to make general public aware, through high school science teacher and engineers involved in infrastructure development activities, about the causes and effect of earthquakes, their consequences and educate them to be prepared for great earthquakes so that loss of lives and property could be minimized.
