“…Figure 2 show that the majority of earthquakes in the East Sea area occur in the depth of 0-75 km (79.27%) equivalent to the crust of the Earth. This result is nearly similar to the previous study on the Northern Luzon subduction model where the authors used shorter period data 1619-1997 (Bautista et al, 2001). This proves the objectivity and reliability of this work.…”

“…Based on the relation between the seismotectonics and geodynamic, the East Sea is a part of Southeast from east to west at the rate of 50 mm/yr (Yingchun Liu et al, 2007) or 55.6 mm/yr (Le Huy Minh et al, 2014). The Eurasian plate move north-west nearly 10 mm/yr (Bautista et al, 2001, Yingchun Liu et al, 2007, Le Huy Minh et al, 2014. And the Australian migration in the north-east direction moves at the speed of 6-7 cm/yr (Phan Trong Trinh et al, 2011).…”

In this paper, seismic activity characteristics in the East Sea area was analyzed by authors on the base of the unified earthquake catalog , including 131505 events with magnitude 3 ≤ Mw ≤ 8.4. The seismic intensity in the East Sea during the period 1900 -2017 is characterized by the earthquake representative level Mw = 4.7. The strong earthquake activity in the East Sea area clearly shows the regularity in each stage. In the period from 1900 to 2017, the East Sea area has four periods of strong earthquake activity, each stage is nearly 30 years with particular characteristics. The distribution of the maximum earthquake quantities by years has a cyclicity in all four periods. In each stage there are 1-2 strong earthquakes with M max ≥ 8.0. The strong earthquakes with M max ≥ 7.5 have occurred by a repeatable rule of 3-5 years in all four stages. This allows the prediction of the maximum earthquake repeat cycle of M max ≥ 7.5 in the study area is 3-5 years. In other hand, the maximum magnitude values for the East Sea region has assessed by GEV method with several different predict periods (20, 40, 60, 80, 100 years), with predicted probability 80%. We concluded that it is possible that earthquake have M max = 8.7 will occur in next 100 years.

“…The tsunami source considered in this paper is generated by a giant earthquake of magnitude M w above 9, which is considered as the worst case scenario by Megawati et al [15]. The adopted fault parameters are derived from studies conducted by Bautista et al [16] and Wu et al [17]. The earthquake-ruptured fault consists of a series of 33 segments, each with its own orientation, size and slip magnitude.…”

The 26 December 2004 Andaman mega tsunami killed about a quarter of a million people worldwide. Since then several significant tsunamis have recurred in this region, including the most recent 25 October 2010 Mentawai tsunami. These tsunamis grimly remind us of the devastating destruction that a tsunami might inflict on the affected coastal communities. There is evidence that tsunamis of similar or higher magnitudes might occur again in the near future in this region. Of particular concern to Malaysia are tsunamigenic earthquakes occurring along the northern part of the Sunda Trench. Further, the Manila Trench in the South China Sea has been identified as another source of potential tsunamigenic earthquakes that might trigger large tsunamis. To protect coastal communities that might be affected by future tsunamis, an effective early warning system must be properly installed and maintained to provide adequate time for residents to be evacuated from risk zones. Affected communities must be prepared and educated in advance regarding tsunami risk zones, evacuation routes as well as an effective evacuation procedure that must be taken during a tsunami occurrence. For these purposes, tsunami risk zones must be identified and classified according to the levels of risk simulated. This paper presents an analysis of tsunami simulations for the South China Sea and the Andaman Sea for the purpose of developing a tsunami risk zone classification map for Malaysia based upon simulated maximum wave heights.
