摘要:

Recordings from a variety of deep‐ocean hydrophone arrays as well as historical accounts and listings of earthquakes from the International Seismological Centre and the National Geophysical Data Center reveal a surprisingly large number of earthquakes from the area of the recently postulated Micronesian subduction zone and from the interior of the Northwestern Pacific Basin, regions generally considered to be aseismic. Unusual patterns of seismicity are observed with lowmagnitude (mb<5.0) earthquakes having epicenters distributed over several hundred kilometers occurring within a few weeks or months of one another. A number of earthquakes within the interior of the Northwestern Pacific Basin are located north and west of Wake Island. Also, the locus of epicenters within the basin suggests a northwest to southeast trending pattern of seismicity. These findings suggest that the world's deep‐ocean basins may be more seismically active than is generally believed, that the distribution of epicenters within the interiors of basins may provide important insights into the stress fields between rising and sinking plate edges, and that efforts should be made to accurately assess the seismicity of ocean interi

摘要:

The National Science Foundation is asking for nominations for the 14th annual Alan T.Waterman Award. The award recognizes outstanding work by a young researcher in any field of science, mathematics, or engineering and is designed to encourage further highquality research.The award was established in 1975 to mark the 25th anniversary of NSF and to honor Waterman, the first director of the Foundation. The recipient of the award receives as much as $500,000 for up to 3 years of research or advanced study in mathematical, physical, medical, biological, engineering, social, or other sciences at the institution of the recipient's choice.

摘要:

This proceedings of an international workshop at the Flood Hazard Research Centre (Queensway, Enfield, Middlesex, U.K.) begins by noting how past British research on flood problems concentrated on refining techniques to implement established policy. In contrast, research covered in North American and Australian publications involved normative issues on policy alternatives and administrative implementation. The workshop's participants included 16 widely recognized scientists, whose origins were about equally divided between Britain and overseas; from this group the workshop's organizers expertly drew ideas for refining British urban riverine flood hazard management and for cultivating links among researchers everywhere. Such intellectual exchange should be of keen interest to flood hazard program managers around the world, to students of comparative institutional performance, to those who make policy on protecting people from hazards, and to hydrologists and other geophysicists who must communicate descriptive information for bureaucratic, political, and public decision‐ makin
