| Popis: | The teleseismic P-wave signal from underground explosions at Novaya Zemlya Island is followed by a coda lasting several minutes. The power level of the coda was measured on Lasa beams for two explosions and on five single seismometer records for one explosion. If we use a statistical approach, the measured coda level can be explained by assuming that the coda is a result of scattering of source-generated Rayleigh waves to P body waves by the island coastlines, river valleys, and other topographic features that are found within a few hundred kilometers of the source. The rate at which the coda decays with time is consistent with the hypothesis of coda generation by scattering. |
