Available in PDF, EPUB and Kindle. Book excerpt: An ocean bottom seismograph was deployed on the seaward side of the Kuril Trench off Hokkaido, Japan, in 5460 m of water, in August 1975 during the joint Soviet-American Tsunami Expedition. During the seven-day record, S-P times were distributed in three groups: 19-24 sec, corresponding to aftershocks of the 10 June and 13 June 1975 earthquakes southeast of Nemuro, Japan and to earthquakes east of Sanriku, Japan; approximately 30 sec, from south of Erimo Peninsula, Hokkaido; and approximately 100 sec, from the Izu-Bonin Islands. Seven earthquakes, with hypocenters well determined by the land seismic net, are studied in detail. A shallow focus earthquake yields typical oceanic mantle velocities shallower than 50 km in the slab which dips under the Japanese archipelago. However, deeper focus earthquakes reveal anomalously high velocities averaged over the upper 230 km, in agreement with the models of Utsu and Oliver and Isacks. Two deep earthquakes, whose paths lie in the Pacific Ocean asthenosphere, suggest a velocity 3% lower than that predicted by Jeffreys-Bullen, in agreement with the above models. Spectral analysis of S arrivals suggests Q sub s values of 1000-1500 for nearby earthquakes and 4000-6000 for longer-distance earthquakes, implying an unusual attenuation mechanism for long travel paths, which enhances the high frequencies.

This book was released on 2002-02-21 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is one of the most significant results of the conference "Science-Technology Synergy for Research in Marine Environment: Challenges for the XXI Century" held in Erice and Ustica, Italy, September 1999. It presents state of the art developments in technology and scientific research in sea floor observatories. Scientific conclusions of earth science and environmental studies obtained from these observatories as well as results from long term monitoring are provided. Descriptions of new technologies enabling deep sea long term observatories are offered and marine environment and risk assessment issues are discussed. This is the first work detailing recent and on going experiments world wide specifically devoted to deep sea multi disciplinary observation systems, the technology enabling sea floor observatories, and the presentation of first results from these systems.
