<p>We investigate the sliding dynamics of two giant submarine landslides and their tsunamigenic capacity in the South China Sea (SCS) region: the Baiyun slide in the Pearl River Mouth Basin and the Brunei Slide in Northwest offshore Brunei. The two slides have comparable sizes with the estimated volumes of 1035 km<sup>3</sup> for Baiyun Slide versus 1200 km<sup>3</sup> for Brunei Slide and areas of 5500 km<sup>2</sup> versus 5300 km<sup>2</sup>. Based on the available geophysical observations, we construct hypothetical scenarios for both slides. By treating the slides as translational mudflow, we are able to reproduce the observed run-out distribution of the Baiyun Slide. The sliding speeds of the failed material could reach 25~35 m/s in both slide events. Both slides could generate devastating tsunamis in the SCS although the tsunamigenic capacity of the Brunei Slide is significantly larger than the Baiyun Slide. Through a series of numerical experiments, we demonstrate that the steepness of the slope and initial water depth of the slides play the key role of determining their tsunamigenic capacity. The tsunami generated by the Baiyun Slide mainly affects the northern part of the SCS. Coastlines including the southern China, central Vietnam, western Philippines suffer the highest tsunami waves.  The tsunami waves generated by the Brunei Slide causes significant impact in northern coasts of Borneo Island, coasts of central and southern Vietnam and Palawan.</p>

AbstractSediments of 13 piston cores from opposite continental slopes of the South China Sea, off southern China and Sabah (northern Borneo), were analyzed by sedimentological methods and dated by oxygen isotope stratigraphy. Sediments mostly consist of hemipelagic clay with 20% carbonate off Sabah and 40% off China. We calculated terrigenous and carbonate accumulation rates for up to 11 time-slices from the Holocene to oxygen-isotope stage 6. Terrigenous accumulation rates generally increase with water depth and reach a maximum at the middle slope off Sabah and at the lower continental slope off China. During glacial and interglacial times this distribution pattern did not markedly change, despite an increase of accumulation rates for glacial periods by a factor of 2 to 5 compared to interglacial periods. Rates are negatively correlated with positions of sea level, which controls the partition of fluviatile terrigenous material for deposition on shelf, slope, and abyssal plain. Carbonate accumulation rates are higher off China by a factor of 2 compared to Sabah, probably indicating higher calcareous plankton productivity.
