| 英文摘要 | It has long been established that plastic flow in the asthenosphere interacts constantly with the overlying lithosphere and plays a pivotal role in controlling the occurrence of geohazards such as earthquakes and volcanic eruptions.Unfortunately,accurately characterizing the direction and lateral extents of the mantle flow field is notoriously difficult,especially in oceanic areas where deployment of ocean bottom seismometers(OBSs) is expensive and thus rare.In this study,by applying shear wave splitting analyses to a dataset recorded by an OBS array that we deployed between mid-2019 and mid-2020 in the South China Sea(SCS),we show that the dominant mantle flow field has a NNW-SSE orientation,which can be attributed to mantle flow extruded from the Tibetan Plateau by the ongoing Indian-Eurasian collision.In addition,the results suggest that E-W oriented flow fields observed in South China and the Indochina Peninsula do not extend to the central SCS. |
