Abstract:

A study of a possible relocation of the seismic array station LHN Lillehammer in south-central Norway is first reported in Part I. One new site is recommended. Part II reports results obtained from three widely separated seismic refraction profiles in Norway and a travel time study for seismic waves in Fennoscandia. The Pn velocities found are very close to 8.20 kmsec. Indications of a phase with velocity of 7.50 kmsec are observed. A phase with a velocity of about 6.60 kmsec is well defined in the seismograms. The amplitude for this phase varies strongly. The velocity for the first direct longitudinal wave varies mostly from 6.00 kmsec to 6.15 kmsec. A crustal thickness from 31 km to 38 km has been determined.
