Description
Summary:Sea wave recordings from the Norwegian Coast and seismic recordings from the long period instruments of the Norwegian Seismic Array (NORSAR) and from the new broad band long period instruments at Kongsberg have been used to study the characteristics and the source locations of long period microseisms in Southern Norway. The disturbances associated with lows in the Lofoten - Vesteralen area normally generate large, regular wave packets (beats) of double frequency (DF), 0.12-0.16 Hz, microseisms at Kongsberg. Meteorological disturbances in the British Isles - Iceland area often generate large PF microseisms and moderate, irregular DF microseisms. Occasionally the sea waves at the West Coast of Norway are sufficiently long period to generage PF microseisms.
