… (B) The background color shows the vertical flow velocity predicted using the S40RTS
tomography model. In both models, velocity decreases near the top of the lower mantle are absent …

The Colorado plateau is a large, tectonically intact, physiographic province in the southwestern
North American Cordillera that stands at ∼1,800–2,000 m elevation and has long been …

New high-resolution P- and S-wave tomography of the United States upper mantle from the
Pacific Coast to the Great Plains reveals strong multi-scale heterogeneity closely correlated …

The Yellowstone supervolcano is one of the largest active continental silicic volcanic fields in
the world. An understanding of its properties is key to enhancing our knowledge of volcanic …

… The tomography models we present are a major expansion of the P and S tomography
presented by Schmandt and Humphreys [2010]. The only methodological difference is that we …

Dieses Buch soll der Entwicklung Rechnung tragen, daß strömungsmechanische Probleme
in Forschung und Entwicklung zunehmend durch den Einsatz leistungsstarker Rechner und …

The correspondence between seismic velocity anomalies in the crust and mantle and the
differential incision of the continental-scale Colorado River system suggests that significant …

… In this paper we discuss the Pacific Northwest portion of our recent tomographic models (Schmandt
and Humphreys, 2010a) to focus on a prominent but previously unresolved “curtain” …

… The scalar b is used to control the relative weight of the P and S data sets. In the model …
weighted by choosing the value of b such that ∥d P ∥ = b*∥d S ∥, b = 1.52. Damping the …

… Figure 2b also shows a number of weaker phases arriving between ScS and PKIKP 2 , but
are less consistent with the synthetics (Figure 1b). These phases may represent phases that …
