Abstract

The Manila trench in the South China Sea (SCS) is identified as being most susceptible to the future major earthquakes. Once a submarine earthquake occurs, the coastal areas and ocean engineering projects around SCS will be affected. Based on the Sanya new airport project, this paper presents an analysis of tsunami impacts to the project region. A series of numerical simulations of tsunami are carried out and compared under different magnitudes of earthquakes. An extreme tsunami induced by a giant earthquake of M9.3 is simulated and analyzed in detail. The tsunami propagation scenarios and surface elevation in the region are presented. The inundation map and flow velocity distribution are analyzed. The impacts of this human project to the coasts are discussed by comparing tsunami wave height with and without the artificial island. According to the numerical results and relevant analysis, the giant tsunami will have great impacts to the artificial island.

南海三亚新机场极端海啸风险分析

南中国海的马尼拉海沟被认为是未来最容易发生大地震的区域。一旦发生海底地震，南海周边沿海地区和海洋工程将受到影响。本文以三亚新机场工程为例，分析了海啸对项目区的影响。对海啸进行了一系列数值模拟，并对不同震级下的海啸进行了比较。对一次9.3级大地震引发的极端海啸进行了模拟和详细分析。给出了该地区海啸传播情景和地表高程。分析了淹没图和流速分布。通过比较有人工岛屿和没有人工岛屿的海啸波高，讨论了这一人类工程对海岸的影响。根据数值结果和相关分析，大海啸将对人工岛屿产生很大的影响。

期刊介绍： Journal of Earthquake and Tsunami provides a common forum for scientists and engineers working in the areas of earthquakes and tsunamis to communicate and interact with one another and thereby enhance the opportunities for such cross-fertilization of ideas. The Journal publishes original papers pertaining to state-of-the-art research and development in Geological and Seismological Setting; Ground Motion, Site and Building Response; Tsunami Generation, Propagation, Damage and Mitigation, as well as Education and Risk Management following an earthquake or a tsunami. We welcome papers in the following categories: Geological and Seismological Aspects Tectonics: (Geology - earth processes) Fault processes and earthquake generation: seismology (earthquake processes) Earthquake wave propagation: geophysics Remote sensing Earthquake Engineering Geotechnical hazards and response Effects on buildings and structures Risk analysis and management Retrofitting and remediation Education and awareness Material Behaviour Soil Reinforced concrete Steel Tsunamis Tsunamigenic sources Tsunami propagation: Physical oceanography Run-up and damage: wave hydraulics.
