Finite-Element Modeling of the Blockage and Scattering of Lg Wave Propagation

摘要

The objective was to investigate the blockage and scattering of Lg wavepropagation due to lateral crustal heterogeneities; the particular case comparing paths across the Barents Sea, across the Baltic shield from Novaya Zemlya, and across the Baltic shield from the Kola Peninsula. The emphasis was to quantify the presence of a large basin in the propagation path.
