Shear wave splitting in the Appalachians and the Urals: A case for multilayered anisotropy
Observations of shear wave splitting in the northeastern U.S. Appalachians and in the foredeep of the Urals vary significantly with the back azimuth and incidence angle of the incoming phase. TheseExpand

Färoe‐Iceland Ridge Experiment 2. Crustal structure of the Krafla central volcano
The seismic velocity structure of the Krafla central volcano is characterized by large variations in compressional velocity. A 40 km wide high-velocity dome extends from the lower crust (11–14 kmExpand

Färoe‐Iceland Ridge Experiment 1. Crustal structure of northeastern Iceland
Results from the Faroe-Iceland Ridge Experiment (FIRE) constrain the crustal thickness as 19 km under the Northern Volcanic Zone of Iceland and 35 km under older Tertiary areas of northeasternExpand

An inverse approach to signal correlation
A simple mathematical inverse method is used to correlate two time series D(x) and R(t), where these two signals are related to each other by the mapping function x(t). The mapping function describesExpand

Tomographic image of the Mid‐Atlantic Plate Boundary in southwestern Iceland
The 170 km South Iceland Seismic Tomography (SIST) profile extends from the west and across the Mid-Atlantic Ridge spreading center in the Western Volcanic Zone and continues obliquely through theExpand

The cross-convolution method for interpreting SKS splitting observations, with application to one and two-layer anisotropic earth models
We present a new method for determining anisotropic earth models using observations of split shear waves (such as SKS). The method consists of first constructing two time-series, x(t) and y(t), thatExpand

Crustal isostasy indicates anomalous densities beneath Iceland
Recent seismological determinations of crustal thickness in Iceland, made mainly through identification of wide-angle PmP and SmS reflections, indicate that the depth to the Moho deepens from 11 kmExpand

Compressional and shear velocity structure of the lithosphere in northern Iceland
Abstract Seismic data from the B96 array in northern Iceland are used to constrain the compressional and shear velocity structure of the crust and uppermost mantle in northern Iceland, at the westernExpand

Seismic attenuation in the crust at the mid-Atlantic plate boundary in south-west Iceland
SUMMARY Very little seismic attenuation occurs in the mid to lower crust of south-west Iceland. The lowest path-averaged quality factor for a wave turning in the mid to lower crust (12-20 km) is QP =Expand
