Describes major earthquakes of 1976 and recent developments in earthquake detection. (MLH)

Seismological research last year was directed toward several fundamental problems. Advances were made in the computation of theoretical seismograms for complex structures and sources. (BB)

Important areas of geodynamics research for the future are the thermal structure and the volatile content of the crust and upper mantle. (BB)

Presented is a review of papers presented at the 25th International Geological Congress held August 16-25, 1976, Sydney, Australia. Topics include precambrian geology, tectonics, biostratigraphy, geochemistry, quaternary geology, engineering geology, planetology, geological education, and stress environments. (SL)

Describes the results of analyzing world wide seismic profiles to develop a precise scale of regional, continental, and global unconformities for dating events in geologic history. (SL)

Seismic events which took place during 1982 form the focus of this review on 1982 seismic research activities and projects. Funding problems for local and other networks, earthquake-prediction research (funded by National Earthquake Hazards Reduction Act of 1977: P.L. 95-124), use of computers, and aftershocks are among the areas addressed. (JN)

Lists the names and addresses, in alphabetical order, of 381 known professional organizations of societies in earth science all over the world. Another list of names and addresses of the fifty U.S. State surveys is also supplied. (GA)

Reviews symposia and meetings concerned with the polar research in the past year. Topics include drilling programs, sea ice and icebergs, and mineral deposits. (MA)

Presents the latest developments concerning the following topics: astrogeology, coal, deep sea drilling project, engineering geology; environmental geology, exploration geophysics, geochemistry, geodynamics project, hydrology, industrial minerals, international geology, mapping, mathematical geology, metals, mineralogy, oil and gas, invertebrate…

Geophysical activity increased in 1978, especially seismic gas and oil exploration in the United States and its waters. (BB)

Provides results of a survey of employment patterns of women in the geoscience fields. Results are compared to a similar 1971 survey; trends indicate that while the position of women has improved they are still under-employed and underpaid in most fields. (SL)

Expansion of activity and confirmation of new technological directions characterized several fields of exploration geophysics in 1977. Advances in seismic-reflection exploration have been especially important. (Author/MA)

An overview is presented of major research studies, scientific events, and issues of concern during 1981 in the field of geology. Thirty-four areas are reviewed ranging from archeological geology to volcanology. (DC)
