The Pacific Coastal States form a complex geologic environment in which the crust and lithosphere have been continuously reworked. We divide the region tectonically into the southern transform regime of the San Andreas fault and the northern subduction regime, and summarize the geophysical framework with contour maps of crustal thickness, lithospheric and seismicity cross sections, and results. The USGS, for example, operates only six observatories in the lower continental United States [Love and Finn, ]. While the present distribution of observatories is sufficient to resolve geomagnetic activity on a broad continental scale, storm‐time activity can be geographically localized, especially underneath the auroral oval [e.g.

@article{osti_, title = {Continental crust: a geophysical approach}, author = {Meissner, R.}, abstractNote = {This book develops an integrated and balanced picture of present knowledge of the continental crust. Crust and lithosphere are first defined, and the formation of crusts as a general planetary phenomenon is described. The background and methods of geophysical studies of the. For north‐south induction, once‐per‐century geoelectric amplitudes across large parts of the United States have a median value of V/km; for east‐west geomagnetic variation the median value is V/km. At some locations, once‐per‐century geoelectric amplitudes exceed 3 V/km. Integrated geologic and Geophysical Studies of North American Continental Intraplate Seismicity Article (PDF Available) in Special Paper of the Geological Society of America January. Abstract. Records from broadband digital stations have allowed us to map regional variations of Lg coda Q across almost the entire United States. Using a stacked ratio method we obtained estimates of Q 0 (Lg coda Q at 1 Hz) and its frequency dependence, η, for event-station sets of estimates were inverted using a back-projection method to obtain tomographic images showing.

More than 2, published heat-flow values are now available for the United States, although the distribution of these data is very uneven, with most data sites in the western United States. Thick Precambrian cratons, disrupted by early plate tectonics, are presently found in all continents; they contribute more than 70% to the continental are characterized by a thick crust (45–50 km) with high velocities (> km/s) in the lower part. The two other crustal types were generated by modern plate tectonics: the orogensby convergence and plate collisions, most of.
