Summary Monochromatic components of the seismic noise have been detected in the NORSAR area. The most prominent are near 2.08 Hz and 2.78 Hz. The geographical distribution and the variation with time is studied, and also the particle motion and wave propagation. A source for the 2.78 Hz peak has been found at a hydroelectric power plant, but the sources for the other spectral peaks are still unknown.
