The Trans-Alaska Crustal Transect (TACT) Across Arctic Alaska

10 September 1997
This special section of the Journal of Geophysical Research addresses the composition and structural evolution of the lithosphere in northern Alaska. Investigations reported in this section were mainly undertaken as part of the Trans- Alaska Crustal Transect (TACT), an integrated geological and geophysical transect of the entire Alaskan lithosphere along a north-south corridor undertaken from 1984 to 1992.

EDGE and Related Seismic Projects, Onshore-Offshore California

10 April 1991
The continental margins hold a special interest to Earth scientists because they mark the complex transition from oceanic to continental crust. This transition often involves a number of interacting processes, including subduction, accretion, and deformation of the oceanic lithosphere and growth and modification of the continental lithosphere, particularly the crust.

Modeling Crustal Deformation

10 March 1993
This special section on Modeling Crustal Deformation presents a collection of research articles prepared by several participants in the AGU Chapman Conference on Time-Dependent Positioning.


10 March 1996
For these reasons, the history of large earthquakes on faults must, for the most part, be learned from the geological record.

The Transition Zone

Anton Hales Symposium

10 April 1983
This volume of the Journal of Geophysical Research is devoted to Anton L. Hales. It contains many of the papers presented at the Anton L. Hales Symposium on "Some Recent Advances in Geophysics" held at The University of Texas at Dallas (UTD) on October 5th, 1981, to honor Professor Hales on his retirement from UTD at the age of 70.

Seismic Anisotropy

10 July 1990
Fluid-filled fractures and microcracks are the most stress sensitive component of crustal rock and often determine the pathways and volume of crustal fluid movement. If we are to comprehend the role of fractures and fluids in tectonic processes, to formulate an accurate hypothesis for phenomena precursory to catastrophic seismic failure, or to monitor hydrocarbon and geothermal reservoirs for the presence or absence of major fluid pathways, we must understand how seismic waves interact with the fracture, crack, and microcrack structures within the rock mass.

Stanford Q Conference

10 October 1980
The attenuation of seismic waves,a direct measure of an elasticity,is an important potential source of information concerning the chemical and physical properties of the earth's crust and deeper interior.
