“…The return period of Manila Trench earthquake at each moment magnitude is summarized in Table 1 [9]. Another two important fault parameters namely width of segments and dislocations were referred to study conducted by Mardi et al [2]. Mardi et al utilized empirical equations proposed by Papazachos et al [11] in order to calculate width of the fault segments.…”

“…The tsunami hit west-coast of Peninsular Ma-laysia resulting to properties destructions and loss of life of 68 people, mostly located in Penang, Langkawi, Kedah and Perak [1]. Until today, east-coast of Peninsular Malaysia is still safe from any tsunami disaster, but in recent years, there are studies that stated the existence of an earthquake epicenter located at South China Sea which can affect the east-coast of Peninsular Malaysia, recognized as Manila Trench [2][3] [4]. The tsunami is expected to reach east-coast of Peninsular Malaysia within few hours.…”

In recent years, studies regarding a new source of tsunami-genic earthquake at South China Sea region known as Manila Trench earthquake have attracted the attention of many researchers. It is expected that this subduction zone is capable to trigger large moment magnitude earthquake and affects countries located within South China Sea. The objective of this study is to project tsunami wave height and arrival time generated from Manila Trench earthquake towards coastal areas located along east-coast of Peninsular Malaysia. This study focuses on simulating tsunami at four different moment magnitudes by using TUNA-M2 model to record wave height and arrival time at the offshore areas. Then the Green’s law is used to approximate reliable tsunami wave height when approaching onshore. Results obtained in this study showed that tsunami waves from Manila Trench are estimated to arrive at coastal areas of east-coast Peninsular Malaysia between 9.1 to 10.25 hours post-earthquake occurrence. The observation points located at offshore of Kelantan are anticipated to experience the highest wave height as compared to other observation points located at offshore areas of Terengganu and Pahang. This study is important to the coastal communities as it provides vital information on possible tsunami occurrences in the future.

“…However, this study is implemented as an approach to determine the most significant fault parameters among the reviewed fault parameters, that create the potential worst-case tsunami scenario impacting the coastal areas located at the eastcoast of Peninsular Malaysia. TUNA-M2 model is used to simulate the Manila Trench earthquake tsunami developed from differ-ent fault parameters with the moment magnitude of Mw: 9.3 proposed by Liu et al [2], Nguyen et al [6] and Mardi et al [7] and Mw: 9.35 proposed by Wu and Huang [5]. This study only considered the Manila Trench earthquake source with six fault segments and utilized the rake angle of 90˚ to indicate the potential worst-case scenario.…”

“…In 2016, the study done by Mardi et al [7] used the six divided fault segments as suggested by the 2006 USGS Tsunami Source Workshop, utilizing the Papazachos et al [10] empirical equations to determine the width of fault segments. The values calculated for each fault segment width are ranging from 53 km to 88 km.…”

“…In 2015, Ren et al [11] conducted a research to study the Manila Trench earthquake tsunami with moment magnitude of Mw: 8.0 and the worst-case scenario (Mw: 9.3) by using the weakly dispersive model (FUNWAVE). However, this study utilized TUNA model to perform tsunami simulation from Manila Trench by using fault parameters proposed by Liu et al [2], Wu and Huang [5], Nguyen et al [6], and Mardi et al [7]. TUNA is developed by the research team from Universiti Sains Malaysia (USM) to simulate a complete tsunami process with three different modules, generation (GE), propagation (M2) and, run-up and inundation (RP).…”

Manila Trench subduction zone is capable to produce high magnitude of earthquake event that can generate a deadliest tsunami disaster. The 2006 tsunami source workshop conducted by United States Geological Survey (USGS) had classified Manila Trench as the most hazardous potential earthquake generated tsunami source in South China Sea. The giant megathrust rupture from Manila Trench has the ability to create an earthquake as powerful as the Great Tohoku tsunami in 2011 and the Indian Ocean tsunami in 2004. This technical paper aims to review the fault parameters used by different researchers in investigating the possibility of tsunami occurrences generated from Manila Trench earthquake to the coastal areas of Terengganu, Malaysia which is located within the vicinity of South China Sea. The selected fault parameters were simulated by using TUNA model in order to study the potential effects of Manila Trench earthquake induced tsunami. The outcomes of the simulation are the wave height and wave arrival time. At the end of this technical paper, an intensive approach is implemented to select the most significant fault parameters that create the potential worst-case tsunami scenario towards Terengganu coastal areas in terms of the highest and fastest first wave arrived.
