Detection Seismology - A Summary

The report gives a review of the work conducted and the scientific reports submitted under the Contract. The research group at the Seismological Observatory, University of Bergen, concentrated on Noise and signal coherence study, the study of the crustal effect on the subarray signal, and the study of long period data. Within this wide frame, this group looked into problems relevant to detection seismology and related topics and made extended use of digital data from the NORSAR array. While for the first two fields the data actually recorded by the NORSAR installation was used, the NORSAR long period data was not available before the expiring data of this contract. Consequently the long period data base has consisted partly of seismograms from the Norwegian Standard Stations and partly of LASA data.
