| Summary: | European History at Depth The preferential alignment of mineral grains as a result of flow direction can polarize seismic waves traveling through Earth's interior, based on velocity and direction. Zhu and Tromp (p. 871 , published online 8 August) mapped this anisotropy beneath the European continent and the North Atlantic Ocean—which are products of several tectonic events across varying temporal and spatial scales—using seismic tomography. The model generated correlates well with plate motion in the region, and, compared to geodetic measurements, much of the anisotropic features are consistent with modern strain rates. Some features below Eastern Europe, however, appear to be remnants of tectonic events that occurred over 350 million years ago. |
