The Sulu Trench is an oceanic trench in the Pacific Ocean, located west of the islands of Mindanao and Sulu in the Philippines. The trench reaches a depth of about 5,600 metres (18,400 ft), in contrast with the average depth of the South China Sea of about 1,500 metres (4,900 ft).

The Negros Trench is an oceanic trench located northeast of the Sulu Trench and west of Negros Island Region in Visayas, the trench is located in the Sunda Plate in the southwestern region of the Pacific Ocean. The depth of the Negros Trench is unknown, in contrast it's neighboring trench the Sulu Trench has a depth of 5,600.

2020年12月25日 · SE-dipping Sulu Sea subduction likely occurred along the Negros-Sulu trenches, and produced arc volcanism from ∼4 Ma. The Sulu Sea and the adjacent sea basins (e.g., Celebes and SCS) are situated at the junction between the Eurasian, Philippine Sea, and Indo-Australian plates.

The Negros trench and the Sulu trench accommodate the subduction of the Sulu Sea plate, while the Cotabato trench is associated with the subduction of the Celebes lithosphere (Yumul et...

2014年12月1日 · The SE Sulu Sea plate is subducting beneath the Negros and Zamboanga Peninsula along the Sulu-Negros Trench (Pubellier et al., 1991, Castillo et al., 2007). The Sulu Arc is a NE-trending linear chain of small volcanic islands along the boundary between the Sulu and Celebes Sea (Castillo et al., 2007).

2020年12月1日 · The Negros and Sulu Trenches accommodate the eastward and southward subduction, respectively, of the SE Sulu sub-basin (Rangin et al., 1999, Hall and Spakman, 2015). North of the SE Sulu sub-basin is the Palawan micro-continental block which has collided with the oceanic part of the island arc system.

2023年1月31日 · Despite its active seismicity and tectonics, the Negros–Sulu Trench System (NSTS) remains understudied, and its submarine geomorphological features are poorly constrained. In this study, we mapped the frontal wedge variations, submarine canyons, lineaments, and submarine landslides in the active margin of the Sulu Sea using high-resolution ...

2008年3月1日 · The Negros trench and the Sulu trench accommodate the subduction of the Sulu Sea plate, while the Cotabato trench is associated with the subduction of the Celebes lithosphere (Yumul et...

Countries surrounding the Sulu Sea are affected by tsunamis in the Sulu Trench and the Negros Trench. The Sulu Trench was divided into two segments (ST1 and ST2) following Salcedo [1]. Mardi et al. [6] carried out numerical modelling of tsunamis due to earthquakes at the Manila Trench and the Sulu Trench.

2021年2月11日 · In this paper, we mainly focus on the structure and core functions of the real-time seismic monitoring and processing system in SCSTAC in the context of tectonic setting of the South China Sea and neighboring areas and the historical earthquakes and tsunamis activities, in order to provide tsunami warning information for the swift and accurate e...
