The authors obtained remarkable results for tidal control of volcanic earthquakes and ocean bottom hydrothermal activity. An OBSIH (Ocean Bottom Seismometers with Hydrophone) was used for all observations. Volcanic earthquake activity associated with the 1983 Miyake Island eruption was high at high-tide and/or low-tide. Observations in three hydrothermal areas, the southern Mariana Trough, the TAG area in the Mid-Atlantic Ridge and the middle Okinawa Trough, showed the existence of low-frequency pulses called pressure pulses having a good correlation with semi-diurnal and diurnal changes in relation to tidal forces. An increase of pressure pulses suggests a hydrothermal upwelling from the vents. It is difficult to state why volcanic and hydrothermal activities are controlled by the ocean tide or the earth-tide. Similar variations occurred during the most resent volcanic activity on Miyake Island in July-September, 2000. Using the 2000 Miyake Island volcanism, a hypothetical interpretation is presented.","PeriodicalId":39875,"journal":{"name":"Journal of the Geodetic Society of Japan","volume":"30 20 1","pages":"424-433"},"PeriodicalIF":0.0,"publicationDate":"2001-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.11366/SOKUCHI1954.47.424","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64262750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Estimated oceanic Qs of the long-period tides are about 3, which show that the ocean is heavily damped system. Some far-reaching tidal energy fluxes, however, exist. Equatorial eastward flux from the coast of South Africa to the Pacific especially stands out. LFrom the point of view of wave dynam ics, contrary to the tidal energy flux in the tropics, wave's energy propagates in the westward direction. With the relation between the energy flux of wave and group ve locity, the westward direction shows that the energy flux corresponds to long Rossby wave. Moreover, this relation clearly shows existence of short Rossby waves in the mid latitudes. LFrom the point of view of planetary scale dynamics, zonally averages of dy namic tide and tidal currents show existence of global non-equilibrium response, which is similar to a particular solution of constant depth ocean. The global response may corresponds to the deviation from the equilibrium tide in zonally averaged admittance, which is found in the analysis of altimeter data.","PeriodicalId":39875,"journal":{"name":"Journal of the Geodetic Society of Japan","volume":"47 1","pages":"551-557"},"PeriodicalIF":0.0,"publicationDate":"2001-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64262789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
