Coastal Sediments
Dating of coastal deposits in the Andaman Islands provides ages of tsunami-events that affected the coast during Pleistocene and Holocene. Luminescence-dating methods are reliable to determine the age of beach sediments. Radiocarbon-dating will be applied to get independent age control. Quartz and Feldspar will be used for luminescence-dating and organic rich material will be dated with the radiocarbon-method. The results  

will be compared with similar deposits on the south-Indian coast. The measured ages will give a chronology of past tsunami-events in the Bay of Bengal and the very likely trend of future major tsunami-events.
