Geophysics News 1990

Published by the American Geophysical Union as part of the Special Publications Series.

The last two years have witnessed many major geophysical events such as the Loma Prieta earthquake, new insights into plate motions, new seismic and mid?]ocean ridge observational programs, and new views of a distant plant. The following sampling of news in geophysics begins with the world's deepest rocks and ends with powerful blast waves from major solar flares and the dramatic discoveries of Voyager 2. In between these events is a rich continuum of inquiry and observation into the dynamics of our environment and a search for connections among its parts.

The articles in Geophysics News 1990 were originally written in response to a request by the American Institute of Physics for contributions by its member societies to its publication of Physics News in 1990. Condensed versions of some of these articles have appeared in Physics News. However, in the absence of a comparable publication devoted solely to a summary of news in geophysics, we offer the collection of AGU's full submission of articles. We hope you will find this to be a useful and stimulating source of information.
