Norwegian Seismic Array (NORSAR)
Abstract
The research activities are documented in 10 reports, which may be summarized as follows: The first report presents a study on interference of surface waves arriving simultaneously at the NORSAR array from more than one direction. Then follow four reports based on short period wave studies, one deals with travel time modelling using a continental array, one with theoretical amplitude calculations in comparison with NORSAR observations, one with upper mantle structure investigations using the Tau inversion method and one with detection of waves converted from P to S in the mantle. The next report discusses bounds on long term noise variability, whereas the following one contains a work on short period discrimination using a multivariate autoregressive representation of P-waves. The last three reports are on statistical methods well suited for analyzing seismic data; the first one introduces a measure of association for spatial variables, the second one describes a criterion for determining the order of an autoregressive model, and the third one is a continuation of an earlier work on spectral estimation for spatial data.
