Trigger Mechanisms

This study presents a calibration of CAT-in-a-Box and intensity-based index trigger mechanisms for parametric tsunami catastrophe bonds. Trigger conditions for the former are based on fundamental event characteristics, such as earthquake location and magnitude, whereas those for the latter utilize tsunami wave height measurements at a series of observation stations. These solutions are illustrated for a building portfolio in Iwanuma City in Miyagi Prefecture, Japan, by considering a new seafloor observation network S-net off the Tohoku-Hokkaido coast of Japan. Performances of the two types of parametric solutions are quantitatively evaluated and compared with each other to discuss their advantages and disadvantages.

Tsunami Wave Height

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.

Tohoku Tsunami

The 2011 Great Tohoku Earthquake and Tsunami in March had caused a lot of damages to people and infrastructure in Japan. With a giant tsunami height plus the subsidence due to earthquakes have destroyed most o f the nearshore constructions and coastal zone areas. According to measured data from the survey group (Mori et al. 2011); maximum tsunami wave height measured at the Nanakita area is about 14m. This Tsunami made the topography of this region changed drastically. Many breaching places occurred along the coast and river mouth. This study will focus on investigating the mechanisms of sediment transport and hydrodynamics leading to the river mouth was closed in about five months after the event and then breached in a different location during the river flood.
