| The Okinawa Trough, lying between Japan and Taiwan, is a backarc basin formed by extension within the continental lithosphere behind the Ryukyu trench-are system. Stress directions associated with the two last extensional phases in the southwestern Okinawa Trough have been deduced from a comparison with analog modeling: the direction of extension is N150 degrees for the Pleistocene phase of extension (2-0.1 Ma) and N170 degrees for the late Pleistocene-Holocene phase of extension (0.1-0 Ma). The present-day Ryukyu volcanic are, a narrow continuous feature extending from Japan to Taiwan, is located on the eastern side of the Okinawa Trough, 80-100 km above the Wadati-Benioff zone, the minimum depth for emplacement of are magmatism. Scarce present-day... |
