We determined principal horizontal stress orientations from analyses of borehole breakouts and drilling-induced tensile fractures by using wireline logging formation microresistivity images and caliper data. The maximum horizontal stress orientation at C0009 is approximately parallel to the convergence vector between the Philippine Sea plate and Japan, showing a slight difference with the stress orientation which is perpendicular to the plate boundary at previous NanTroSEIZE sites C0001, C0004 and C0006 but orthogonal to the stress orientation at site C0002, which is also in the Kumano forearc basin. These data show that horizontal stress orientations are not uniform in the forearc basin within the surveyed depth range and suggest that oblique plate motion is being partitioned into strike-slip and thrusting. In addition, the stress orientations at site C0009 rotate clockwise from basin sediments into the underlying accretionary prism.completedSolid-earth geophysicsbasinsboreholesExpedition 319fore-arc basinsfracturesIntegrated Ocean Drilling ProgramIODP Site C0009Kumano BasinNankai TroughNanTroSEIZENorth PacificNorthwest PacificorientationPacific OceanPhilippine Sea Plateplate boundariesplate tectonicsrotationstresssubduction zoneswell-loggingWest Pacificurn:org.iodp:exp:319urnlargerWorkCitationcampaignurn:org.iodp:exp:319:site:C0009urnlargerWorkCitationstudyurn:org.iodp:exp:319urnlargerWorkCitationcampaignEnglishgeoscientificInformation136.2000137.000032.500033.3000application/pdfunknownSEDIS Publication Catalogue
