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.
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.
