A post-tsunami survey was conducted along the Myanmar coast two months after the 2004 Great Sumatra earthquake ( Mw=9.0) that occurred off the west coast of Sumatra and generated a devastating tsunami around the Indian Ocean. Visual observations, measurements, and a survey of local people's experiences with the tsunami indicated some reasons why less damage and fewer casualties occurred in Myanmar than in other countries around the Indian Ocean. The tide level at the measured sites was calibrated with reference to a real-time tsunami datum, and the tsunami tide level range was 2–3 m for 22 localities in Myanmar. The tsunami arrived three to four hours after the earthquake.

ABSTRACT In the aftermath of the 2004 Indian Ocean (Sumatra-Andaman) tsunami, numerous survey teams investigated its effects on various locations across the Indian Ocean. However, these efforts were focused only on sites that experienced major destruction and a high death toll. As a consequence, some Indian Ocean coastal megacities were not examined. Among the cities not surveyed was Mumbai, the principal west coast port and economical capital of India with a population of more than 12 million. Mumbai is at risk of tsunamis from two major subduction zones in the Indian Ocean: the Sumatra–Andaman subduction zone (SASZ) and the Makran subduction zone (MSZ). As a part of the present study, we conducted a field survey of the 2004 Indian Ocean tsunami effects in Mumbai, analysed the available tide gauge records and performed tsunami simulations. Our field survey in 2018 January found run-up heights of 1.6−3.3 m in the Mumbai area. According to our analysis of tide gauge data, tsunami trough-to-crest heights in Okha (550 km to the north of Mumbai) and in Mormugao (410 km to the south of Mumbai) were 46 cm and 108 cm, respectively. Simulations of a hypothetical MSZ Mw 9.0 earthquake and tsunami, together with the Mw 9.1 Sumatra–Andaman earthquake and tsunami, show that the tsunami heights generated in Mumbai by an MSZ tsunami would be significantly larger than those generated by the 2004 Sumatra–Andaman tsunami. This result indicates that future tsunami hazard mitigation for Mumbai needs to be based on a potential large MSZ earthquake rather than an SASZ earthquake.

A huge earthquake of magnitude M 9.0 occurred at 00:58 (UT), December 26, 2004, in the sea off the west coast of northern Sumatra, Indonesia, followed by a huge tsunami that hit almost all coasts facing the Indian Ocean. We conducted a field survey in the residential area of Banda Aceh, the town of the severest damage by the tsunami, on the west coast of the northernmost point Sumatra, Sigli City, about 80 kilometers east of Banda Aceh three-four weeks after the event. In Banda Aceh, almost all houses in the residential area about 2 km from the coast were swept away, while houses more than 3 km rarely were. Inundation continued about 5 to 6 km from the shoreline. In Lhoknga and several villages on the west coast of Sumatra Island near Banda Aceh, where tsunamis 15 to 30 meters high hit coastal villages, nobody survived. Along the valley about 1 km north of the cement plant, seawater rose to a height of 34.8 m above MSL, which is the highest recorded inundation measured in our survey.

This article explores the private trade networks of English East India Company merchants on the west coast of India during the first half of the eighteenth century. Existing studies of English private trade in the Indian Ocean have almost exclusively focused on India's eastern seaboard, the Coromandel Coast and the Bay of Bengal regions. This article argues that looking at private trade from the perspective of the western Indian Ocean provides a different picture of this important branch of European trade. It uses EIC records and merchants' private papers to argue against recent metropolitan-centred approaches to English private trade, instead emphasising the importance of more localised political and economic contexts, within the Indian Ocean world, for shaping the conduct and success of this commerce.

AbstractAmong the diverse types of merchants active in India during the first half of the second millennium, the ship-owning merchants occupy a prominent position in the coastal areas of western India (especially at ports). These merchants are given distinct epithets nakhuda and nauvittaka, the two terms being occasionally used as interchangeable ones and also in their abbreviated forms in official documents. Known from the medieval Jewish letters of 'India Traders', copper plates, a bilingual inscription, Arabic accounts and epitaphs and Jaina carita (biographical) texts, nakudas and nauvittkas of different religious leanings (Jewish, Muslim and Hindu) illustrate remarkable co-operation and social amity and religious toleration, which underline their importance in the Indian Ocean maritime network prior to AD 1500. Possessing considerable wealth, these ship-owning merchants can be considered as elites in the ports of coastal western India and were also known for their patronage to religious and cultural activities. The paper is presented as a tribute to the memory of Professor Ashin Das Gupta who immensely enlightened us on the ship-owners of coastal western India between 1500-1800.

On 26th December 2004, the countries within the vicinity of East Indian Ocean experienced the most devastating tsunami in recorded history. This tsunami was triggered by an earthquake of magnitude 9.0 on the Richter scale at 3.4°N, 95.7°E off the coast of Sumatra in the Indonesian Archipelago at 06:29 hrs IST (00:59 hrs GMT). One of the most basic information that any tsunami warning center should have at its disposal, is information on Tsunami Travel Times (TTT) to various coastal locations surrounding the Indian Ocean rim, as well as to several island locations. Devoid of this information, no ETA's (expected times of arrival) can be included in the real-time tsunami warnings. The work describes on development of a comprehensive TTT atlas providing ETA's to various coastal destinations in the Indian Ocean rim. This Atlas was first released on the first anniversary of the Indian Ocean Tsunami and was dedicated to the victims. Application of soft computing tools like Artificial Neural Network (ANN) for prediction of ETA can be immensely useful in a real-time mode. The major advantage of using ANN in a real-time tsunami travel time prediction is its high merit in producing ETA at a much faster time and also simultaneously preserving the consistency of prediction. Overall, it can be mentioned that modern technology can prevent or help in minimizing the loss of life and property provided we integrate all essential components in the warning system and put it to the best possible use.

To understand the socially rooted measures in disaster management and reconstruction, we studied Indonesia as amodel fromthe perspective of social flux, by incorporating the latest knowledge in this field. Characteristically, in Indonesian society, people move so frequently that it is difficult for information or knowledge to accumulate; their living and occupational forms are constantly in flux. Because of these characteristics, supporters and local residents of Indonesia have devised a variety of measures for effective disaster management, humanitarian assistance, and reconstruction. However, such measures have often not been positively evaluated – they have been viewed as an immature response of Indonesian society. In this paper, we have positively reviewed the various measures taken in response to the Indian Ocean tsunami of 2004, the Java earthquake of 2006, and the West Sumatra Earthquake of 2009 in order to construct an Indonesian model of disaster management and reconstruction from the perspective of social flux. We hope the proposed model will also prove effective in many other parts of the world.

According to the NOAA earthquake database, at least 31 events have been found in the Indian Ocean in terms of tsunami event since 1900, most of which occurred along the Sunda Trench. In this study, we review the history of tide level measurements and their datasets archives in Thailand, Indonesia, India, and Australia. We collected tide gauge paper charts recording historical tsunamis including the 2004 Indian Ocean tsunami in those countries. As a result, systematic collection of historical tsunami records by tide gauges in the Indian Ocean has been difficult, because few tsunamigenic earthquakes occurred in the Indian Ocean during the instrumentally observed period.
