Tsunami Hazard Assessment at GuangHai Bay of the South China Sea

OnePetroJune, 2021

Abstract The COMCOT model from Cornell University has been optimized, which was validated by 2011 Japan tsunami. The simulation results agreed well with the DRAT buoys from NOAA center. Assessment were implemented by tsunami sources of Manila Trench to evaluate tsunami hazards for the GuangHai Bay of the South China Sea (SCS). The tsunami hazard rank criteria recommended by UNESCOòIOC and the State Oceanic Administration of China has been applied in this paper. Tsunami hazards classifications were divided for the GuangHai Bay by analyzing the simulation results. Preliminary assessment of tsunami hazards have been completed in the paper. INTRODUCTION In recent decades, the 2004 Indian earthquake tsunami and the 2011 Japan earthquake tsunami have caused huge loss of life, property and environmental damage to coastal areas. Considerable efforts have been devoted to study the basic theory of tsunami and improving the tsunami warning system, the coastal countries have also carried out the risk assessment of tsunami disasters for major coastal projects and key support targets. According to the study of potential tsunami seismic fault zones from USGS, the Manila Trench is regarded as the most likely source for tsunami hazards (Li and Yuan, 2016), which will undoubtedly threaten the coast of the China. Many studies mainly focused on the tsunami research (González and Geist, 2009; Burbidge and Cummins, 2009; Heidarzadeh and Kijko, 2011; Megawati and Shaw, 2009; Anawat and Imamura, 2012). The research of potential tsunami disaster in the South China Sea has been extended from the South China Sea to the coastal areas of the mainland (Yu and Ye, 2001; Yu and Wang, 2011; Wang and Yu, 2012; Ren and Wang, 2018; Zhang and Niu, 2020; Yuan and Li, 2021). The criteria of tsunami hazard grade issued by UNESCO/IOC and the China is used to grade the tsunami hazard in the GuangHai Bay of China, which results will provide technical support for the enhancement of marine services in GuangHai Bay. GuangHai Bay is the power base of GuangDong Province in China. TaiShan power plant, the largest coal–fired power plant in Asia, has been put into operation. An installed capacity of 6 million kilowatts of TaiShan Nuclear Power Plant has already been established and successfully taking into operation. Future, wind power projects will also make the TaiShan city to the largest wind power base in GuangDong. With the all–round development of society and economy in GuangHai Bay, the resources of coastline and inshore sea area decrease sharply, and the conflict of ocean utilization function exists in some areas, which is brings new problems to the sustainable development and utilization of GuangHai Bay. Lack of awareness of the conflict between limited marine resources and high–intensity exploitation, it is necessary to ascertain the potential hazard of marine disasters, to identify regional resilience and to objectively understand the level of marine disaster hazard, which provides authoritative disaster hazard information and scientific decision–making basis for national governments to effectively carry out marine disaster prevention and Emergency Management and guarantee the sustainable development of social economy.

Scenarios of Tsunami in the South China Sea by Earthquakes of Source Parameters from Different Scaling Relations

Li, Zhisong (Shanghai Jiao Tong University) | An, Chao (Shanghai Jiao Tong University) | Liu, Hua (Shanghai Jiao Tong University)

OnePetroOctober, 2018

ABSTRACT There has been an increasing number of studies on the tsunami hazards in the South China Sea region since the 2004 Sumatra earthquake. Many of them are carried out based on tsunami scenario simulations, which adopt seismic source models constructed from scaling relations between seismic magnitude/momentum and rupture parameters. Various sets of scaling relations have been proposed on the basis of different earthquake catalogues. In this study, we perform synthetic tests to evaluate the impact of scaling relations on the generation and propagation tsunami waves in the South China Sea. Results show that the range of the affected coastline can be significantly different for an earthquake of the same magnitude using different scaling relations. Additionally, the maximum tsunami wave height near major cities may vary as large as two times. Thus, it is worth further research on the choice of scaling relations for tsunami hazards assessment and the building of early tsunami warning system. INTRODUCTION The Manila subduction zone was identified (Kirby et al., 2006) as having high potentials to generate hazardous tsunamis in the USGS (the United States Geological Survey) tsunami source workshop (Liu et al., 2007). As shown in Fig. 1, seismic events are very active near the Manila Trench. Tsunami from the Manila Trench is a potential threat to coastal countries around the South China Sea (SCS), such as China, Vietnam, Philippines et al. Although studies on tsunami scenarios have been performed (Liu et al.2007, 2009; Wu & Huang, 2009, Megawati et al., 2009, Nguyen et al., 2014), the rupture model and mechanism of the Manila trench is far away from being enough. Eyes were turned to the Manila subduction zone after the 2004 Sumatra tsunami. Basic geometry and orientation parameters were provided by Kirby et al.(2006). But the parameters cannot be employed directly to performing numerical simulations, for the rupture width, the focal depth and the dislocation were not provided. Liu et al.(2007, 2009) provided the source parameters of an earthquake scenario Mw8.0 based on the geometry and orientation parameters of Kirby et al.(2006). The rupture width was identified as 35 km by squaring the region of an earthquake Mw7.3 and its aftershocks in 1999. The dislocation was calculated from the scaling relation of Wells & Coppermith (1994). However, the slip of the sub-fault E6 is the largest among the six sub-faults, which conflicts with geodetic data (Li et al., 2016). Based on geodetic data from Yu et al.(1999), a complex rupture model was provided by Megawati et al.(2009) by splitting the Manila fault into 33 pieces of elements. An earthquake, whose moment magnitude reaches Mw9.4, is probably to dilacerate the whole Manila Trench and brings extreme tsunami. Wu & Huang (2009) also provided a rupture model of an earthquake Mw9.35 by simply comparing the geometric similarity of the Manila fault to the fault of 1960 Chilean earthquake, the 1964 Alaska earthquake, and the 2004 Sumatra earthquake. Nguyen et al.(2014) redesigned the subfaults' geometry and orientation parameters. In fact, except the geometry and orientation parameters of the Manila Trench that proposed by Megawati et al.(2009), the rest models of earthquake source parameters do not meet the scaling relations (SRs) of megathrust fault. Apart from providing all parameters of an earthquake source, they also studied the tsunami impact on the eastern coast of Vietnam (Nguyen et al., 2014), Singapore (Huang et al., 2009) and Taiwan (Wu & Huang, 2009). Liu et al.(2007, 2009) attempted to establish an early tsunami warning system in the SCS so as to mitigate disasters to coastal land areas around the SCS.

A Numerical Study on Tsunami Waveforms and Inundation Along Vietnam Coast in the South China Sea

OnePetroJune, 2018

ABSTRACT Tsunami threatens the coastal sea areas of the South China Sea. In order to figure out the impact of tsunami waves, a scenario of tsunami generated by an earthquake of magnitude Mw9.3 in the Manila trench is studied. A Boussinesq numerical model is adopted to study the impact of tsunami wave to the coastal sea areas of Vietnam and the pattern of tsunami wave during propagation. Leading wave amplitude, arrival time and flow velocity near the target locations, as well as the wave profiles, are presented. INTRODUCTION Two extreme earthquakes, Sumatra earthquake (at 00:58 UTC, 26th Dec. 2004) and Tohoku earthquake (05:46 UTC, 11th Mar. 2011), occurred and triggered a series of devastating tsunamis. Coasts even far away from the epicenter of earthquakes also suffered the loss of lives and properties. Since then, the potential threat of earthquake and tsunami from faults along the Manila Trench steps into the public view of littoral countries around the South China Sea, such as China, Vietnam, Philippines and Singapore et al. Offshore and near-shore structures are exposed to potential damage of waves and currents caused by a tsunami. Studies on the tsunami in the South China Sea, such as fault parameters, threats of an extreme tsunami and early warning system have been carried out in the last two decades. The Manila Trench is an oceanic trench in the west part of the Pacific Ocean, along which the Sunda Plate (part of Eurasian Plate) is subducting under the Philippine Mobile Belt. Fault parameters, such as fault location, geometry, and length, were first published by Kirby & Geist (2006). According to the historical earthquakes that occurred in the region of Manila Trench, the scaling relation and fault parameters, Liu et al. (2009) presented a source model of the Manila faults of magnitude Mw8.0. Based on the fault parameters of the Chile tsunami (1960), the Alaska tsunami (1964) and the Indian Ocean tsunami (2004), Wu & Huang (2009) developed an earthquake source model of magnitude Mw9.35. Megawati et al. (2009) also constructed a source model of magnitude Mw9.0. The number of sub-faults in the source models proposed by Liu et al. (2009) and Wu & Huang (2009) is six, which is inherited from the work of Kirby & Geist (2006); while it is 33 in Megawati et al. (2009). Based on the models proposed by Wu & Huang (2009) and Megawati et al. (2009), Nguyen et al. (2014) developed a new worst case scenario of magnitude Mw9.3, which is adopted in this study.

An Empirical Formula of Evaluation of Wave Amplitude for Trans-Ocean Tsunamis

Liu, Hua (Shanghai Jiao Tong University) | Wu, Wei (Shanghai Jiao Tong University) | Zhang, Zhicheng (Shanghai Jiao Tong University)

OnePetroJune, 2017

ABSTRACT A simplified calculation model of wave amplitude of trans-ocean tsunami in open field is presented. A series of earthquake parameters with different fault length-width ratios are selected. The nonlinear shallow water equations based numerical model is used to simulate the generation and propagation of earthquake-triggered tsunami in a deep ocean. Through numerical experiments, an empirical formula of tsunami amplitude is proposed for the cases of different fault length-width ratio. At last, the accuracy of the proposed formula is checked by comparing with the DART records of the 2011 Japan Tohoku tsunami. INTRODUCTION Two extreme tsunamis have produced devastating damage around the Indian and Pacific Oceans over the last decade. The 2004 Indian Ocean tsunami, which generated from north of Sumatra of Indonesia, attacked many countries around Indian Ocean and led to death of more than 200,000 people. The 2011 Japan Tohoku tsunami brought serious damage to Japan and impacted the coastal regions in the Pacific regions (Kanoglu et al, 2015; Ren et al, 2013). Because the Manila subduction zone of South China Sea has been considered as one of the highest risk tsunami source region, a strong motivation for the investigation on the potential extreme tsunami hazards in the regions of South China Sea appears (Liu et al 2009). The tsunami warning system has been established in some countries. The Japan Meteorological Agency adopted seismic information and one tsunami simulation database to forecast tsunami (Tatehata, 1997; Furumoto et al, 1999). The tsunami database contains the simulation results of around 100,000 cases of potential sources. Once an earthquake occurs, the system will provide arrival time and wave height of the tsunami by searching the location and magnitude of the earthquake in the database. Titov et al (2005) applied buoys inversion method in the Pacific Ocean, which is based on the numerical results of 246 discrete sets of unit sources. The measured data can be obtained by the buoys in deep oceans, which belongs to the deep ocean Assessment and Reporting of Tsunamis system (DART). Liu et al (2009) modelled the Manila Trench as 39 unit plates and proposed a frame of tsunami warning system for the South China Sea by COMCOT and one buoy inversion method. Wu and Ho (2011) developed an improved tsunami inversion method and applied it in 2010 Chile earthquake tsunami. Ren et al (2014) adopted the multi-buoy inversion method for implementing tsunami warning in the South China Sea. Basically, these tsunami warning methods depend on heavy numerical computation. Reymond et al (2012) developed a method for the rapid estimation of tsunami wave heights, either in the deep Pacific Basin by the shallow water equations based numerical model, or at specific shore locations by an empirical transfer function inspired by the Green Law. Jamelot and Reymond (2015) presented the French Polynesian tsunami warning system by combining numerical simulation of the tsunami amplitude in a deep ocean with the nested grids and the empirical transfer function of estimating the tsunami amplitude in the coastal regions.

Abstract We developed a numerical model for the advection of planktonic larvae of Manila clam (Ruditapes philippinarum) in Tokyo Bay that accounts for vertical migration, as well as individual differences in shell length and growth rates of larvae spawned on different dates. Using this model, we simulated the three-dimensional advection of Manila clam larvae in Tokyo Bay. The model was able to generally reproduce the observed larval movement, and the simulated final larval settlement locations were found to be consistent with results of young clam sampling. Introduction The Manila clam (Ruditapes philippinarum), commonly known as " asari" in Japanese, is not only an essential component of the Japanese diet, it is also an environmentally important organism that plays a vital role in the water purification of tidal flats. Land reclamation in Tokyo Bay has dramatically reduced the area of tidal flats and shallows, which are the habitat of Manila clams. As a result, Manila clams now inhabit a patchwork of disconnected tidal flats and shallows between reclaimed areas. However, it is considered that a larval supply network connects these discrete habitats and that this network plays an important role in the survival of the Manila clam in Tokyo Bay. Studies on the Manila clam populations in Tokyo Bay have included those undertaken as part of the " Asari Project" to monitor larvae in the entire Tokyo Bay area(2003); analysis of larval advection using numerical models and estimates of the larval supply network between habitats by Hyuga(2005); and the studies of Yagi et al.(2011). and Otsuka et al.(2010). However, the numerical models employed in these previous studies have treated Manila clam larvae as passive tracers that simply move with the current. Indeed, none of these studies has considered the active vertical migration of clam larvae.

Abstract Roxas Boulevard Seawall is an important part of the urban transportation infrastructure of Metro Manila. It was overtopped several times in the past decade and was subsequently rebuilt. However, recent strong typhoons caused overtopping even after its rehabilitation in 2012, and it became apparent that a more permanent solution was necessary to mitigate its overtopping due to strong typhoons. A coastal engineering study was undertaken to quantify the hazards, and field surveys and testing were carried out to obtain data for input to preliminary and detailed engineering. This paper discusses the application of wave mechanics, numerical modeling, geotechnical engineering and civil engineering design to the analysis of the hazards and the preliminary engineering to redesign this seawall located along a built-up coastline of Manila Bay. Introduction The Roxas Boulevard (RB) Seawall is an important infrastructure of the urban transportation of Metro Manila and water-born transport of the Philippine archipelago. It is thus important for the national government to ensure its functional performance and structural integrity. The Seawall was overtopped by recent strong typhoons that caused flooding in some portions of Manila City. In 2011, storm tides and waves caused the collapse of the RB Seawall and flooded the city. RB Seawall underwent structural rehabilitation but was overtopped by succeeding typhoons. The Department of Public Works and Highways (DPWH), the national agency in charge of national roads, found it necessary to formulate a more permanent solution to mitigate the seawall's frequent overtopping and ensuing coastal flooding, while keeping its tourism attraction of providing an unhampered view of the world-famous Manila Bay sunset. This paper presents a methodology to redesign the Seawall by application of numerical modeling, coastal engineering, geotechnical engineering and civil engineering design to the mitigation of natural ocean hazards along the built-up waterfront
