Sand Sheets on a Beach-Ridge Plain in Thailand: Identification and Dating of Tsunami Deposits in a Far-Field Tropical Setting
Year: 2011
Type: book-chapter
Abstract: IntroductionSurveys of recent tsunamis, especially the 2004 Indian Ocean tsunami, demonstrate that tsunami deposits are different from place to place and that tsunami geology is very complex.This complexity has increased the challenges of identifying and interpreting of past tsunamis in many parts of the world as no set of criteria are suitable in all locations.In this chapter we present a case study of tsunami deposits, both modern and ancient, from Thailand.We discuss further complications and challenges associated with identifying and dating paleotsunami events in this tropical setting that include post-depositional change, the absence of marine microfossils and lack of appropriate materials for dating.Preservation potential of 2004 tsunami deposit in Thailand will also be considered.2004 Sumatra-Andaman earthquake and associated tsunami seemed unprecedented as there was no written or instrumental record of great earthquakes (M > 8) in this region.No event comparable to the 2004 tsunami is recorded in known historical sources from the Indian Ocean region (Dominey-Howes et al., 2007).Surviving historical accounts in Thailand, mainly from European visitors and Indian and Chinese traders to the Siam Kingdom (Thailand) via Takola-or later known as Takau Pa, a major trading southern coastal town, also lack identified accounts of a large tsunami affecting the Thailand Andaman Coast.Accordingly, prior to the 2004 tsunami, Thailand had almost no awareness of tsunami hazards, let alone any warning system or mitigation measures in place.This situation contributed to the loss of life in Thailand during the 2004 tsunami. www.intechopen.com How to referenceIn order to correctly reference this scholarly work, feel free to copy and paste the following: Kruawun Jankaew, Maria E.
