Report of Cruise 2010005PGC, C.C.G. Vessel John P. Tully, 22 September - 2 October 2010, SeaJade-I Seafloor Earthquake Array Japan-Canada Cascadia Experiment, ocean bottom seismometer deployment and active-source...: M183-2/7558E-PDF
This Geological Survey of Canada Open File summarizes the activities undertaken during the deployment phase of the SeaJade expedition (Seafloor Earthquake Array Japan Cascadia Experiment). The main objective of this work is to acquire passive seismic data for earthquake studies. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) provided 35 Ocean Bottom Seismometers (OBS), which were deployed to monitor earthquake activity offshore Vancouver Is. The OBS monitoring will, for the first time, provide information on seismic activity beneath the continental slope and further offshore. This information cannot be provided by land-based seismic networks and therefore will fill a critical knowledge gap essential to the assessment of earthquake hazard due to the Cascadia subduction fault. The second research objective involves an active seismic program to acquire active-source seismic data across a frontal ridge for submarine slide studies and linkages to gas hydrate occurrences.
