Observations and Modeling of Environmental and Human Damage Caused by the 2004 Indian Ocean Tsunami

Geophysical monograph (2015)

Kazuhisa Goto Fumihiko Imamura Shunichi Koshimura Hideaki Yanagisawa

This chapter introduces studies of local inundation of the 2004 Indian Ocean tsunami and explains show how to quantitatively estimate tsunami damage based on field observations, satellite image analyses, and high-resolution numerical modeling results. It talks about the damage to coastal morphology, marine ecosystems, and mangroves at Pakarang Cape, Thailand, and to structures, humans, and mangroves at Banda Aceh city, Indonesia. 17 and 23 m grid digital bathymetric/topographic datasets, were used respectively for those areas, with grid cell resolutions sufficiently fine for comparison with field observation data. From these datasets, a nested grid system spanning the Indian Ocean to the Pakarang Cape coast and Banda Aceh city was produced and the tsunami inundation was calculated. Such high-resolution numerical modeling is useful to elucidate processes of local tsunami inundation, damage generation, and quantitative damage associated with tsunami hydrodynamics: flow depth, hydraulic force, and current velocity.

A Study for the Sediment Transport due to Tsunami along the Natural Coast

PROCEEDINGS OF COASTAL ENGINEERING JSCE (2008)

Takeshi NISHIHATA Kazuhisa Goto Yoshimitsu TAJIMA Tomoyuki Takahashi Fumihiko Imamura

In this study, we investigated the sediment transport due to the 2004 Indian ocean tsunami along the natural coast at Hambantota, Sri-lanka. Bathymetry and topography surveys before and after the tsunami were conducted and the results showed significant erosion by the tsunami, especially around the places where shoreline discontinuations were observed. We conducted a numerical simulation of tsunami propagation as well as the bathymetry change induced by the tsunami. Furthermore, we also estimated the bathymetry change due to the usual sea waves at the coast. Our numerical results suggested that the tsunami has strong bottom shear stress at specific landform such as a river mouth and a cape. We also found that the sediment erosion and accumulation due to the tsunami had been mitigated by usual sea waves after the tsunami.

Decay Process of the Tsunami due to the 2011 Great off the Pacific Coast of Tohoku Earthquake along the Pacific Coast of Japan

Journal of Japan Society of Civil Engineers Ser B2 (Coastal Engineering) (2014)

Kentaro Imai Atsushi Tanobe Yutaka Hayashi Fumihiko Imamura

We analyzed the process decay of tsunami waveform based on the observed one due to the 2011 Tohoku-Oki earthquake. The observed waveforms at 31 stations along the Pacific coast of Japan were divided into four domains with periods and were evaluated respectively for each physical parameter such as the arrival time, the amplification time of tsunami of the later phase, the maximum tsunami amplitude of the later phase and the decay time. We found out that the decay time of the long period component is generally longer than the short period, but in some cases the time of short period component becomes longer than the others, which may be affected by radiation wave due to large scale bathymetric structure such as the Emperor seamount.

Building damage from the 2011 Great East Japan tsunami: quantitative assessment of influential factors

Natural Hazards (2014)

Natt Leelawat Anawat Suppasri Ingrid Charvet Fumihiko Imamura

Based on the classification provided by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), the damage level of buildings impacted by the 2011 Great East Japan tsunami can be separated into six levels (from minor damage to washed away). The objective of this paper is to identify the significant predictor variables and the direction of their potential relationship to the damage level in order to create a predicting formula for damage level. This study used the detailed data of damaged buildings in Ishinomaki city, Miyagi prefecture, Japan, collected by MLIT. The explanatory variables tested included the inundation depth, number of floors, structural material, and function of the building. Ordinal regression was applied to model the relationship between the ordinal outcome variable (damage level) and the predictors. The findings indicated that inundation depth, structural material, and function of building were significantly associated with the damage level. In addition to this new type of model, this research provides a valuable insight into the relative influence of different factors on building damage and suggestions that may help to revise the classification of current standards. This study can contribute to academic tsunami research by assessing the contribution of different variables to the observed damage using new approaches based on statistical analysis and regression. Moreover, practical applications of these results include understanding of the predominant factors driving tsunami damage to structures, implementation of the relevant variables into the proposed, or alternative model in order to improve current damage predictions by taking into account not only inundation depth, but also variables such as structural material and function of building.
