摘要:
Shallow intraplate earthquakes, recently detected along an arcuate zone extending from the northern side of the Caroline Ridge across the western Pacific to the southern end of Kiribati (see cover), may portend a northward shift in convergence between the Indo‐Australia and Pacific plates. Low‐amplitude seafloor structures along this zone indicate recent deformation and, in places, suggest trench‐forearc morphology. These earthquakes and seafloor structures may provide evidence for the formation of a new subduction zone: the Micronesian Trench. The western end of the postulated trench seems to be part of a complex triple junction at the concurrence of the Yap, Mariana, and Micronesian trenches. The eastern end joins the Tonga Trench south of Savaii, Western Samoa. Detailed regional studies will be necessary to delineate further the postulated Micronesian Trench. The fact that important earthquakes indicating this structure were not detected by the existing worldwide network of seismic stations suggests the need for a comprehensive reevaluation of oceanic intraplate seism

摘要:
About a decade ago, the solar physics community decided that its next major project should be the building of a Solar Optical Telescope (SOT) that would be flown on the space shuttle as a Spacelab payload. The National Aeronautics and Space Administration (NASA) deemed the project “facility class instrumentation,” issued an announcement of opportunity, chose investigators, contractors, and a science working group, and began funding SOT planning efforts. After what one source involved with the project called “a long and lusty history,” SOT was cut out of the agency's budget request for fiscal year (FY) 1987, released last month (Eos, February 25, 1986, p. 95). The project may be revived, planners say, but in a scaled‐down, ren

摘要:
A task force of the National Aeronautics and Space Administration (NASA) is producing new launch schedules for NASA's three remaining space shuttle orbiters, possibly supplemented by expendable launch vehicles. In the wake of the explosion of the space shuttleChallengeron January 28, 1986, the task force is assuming a delay of 12–18 months before resumption of shuttle flights.NASA's Headquarters Replanning Task Force, which meets daily, is separate from the agency's Data and Design Analysis Task Force, which collects and analyzes information about the accident for the use of the investigative commission appointed by President Ronald Reaga

摘要:
AGU was formally elected a member of the American Institute of Physics (AIP) on March 14, 1986, at the AIP corporation meeting. Other member societies are the American Physical Society, the Optical Society of America, the Acoustical Society of America, the Society of Rheology, the American Association of Physics Teachers, the American Crystallographic Association, the American Astronomical Society, the American Association of Physicists in Medicine, and the American Vacuum Society.Membership in AIP will bring AGU members direct benefits and will strengthen the community of scientific societies. Of immediate interest to some members will be Pi‐NET (described in the item “Electronic Network Links Physicists,” p. 151), which provides electronic access to abstracts and tables of contents, meeting information, and other services of AIP and all member soci

摘要:
Now that AGU is a member of the American Institute of Physics (AIP) (see item on page 150), AGU members may access Pi‐NET, the Physics Information Network developed by AIP on behalf of its member societies. The electronic network will be available after March 31, 1986, to members of AIP member and affiliate societies for the cost of a local telephone call.This electronic database service provides listings of job opportunities in physics, calendars of meetings, advance abstracts of more than 40 journals published by AIP and member societies, brief announcements and news items, titles of journal articles from AIP's Searchable Physics Information Notices (SPIN) database, and an electronic catalog and on‐line ordering of publications from AIP and member societies. AGU journals will be included in the database shor
