“…The recent 2004 Indian Ocean tsunami deposits in the land along the south east coast of India have signatures of different geological features, which had inundated to deeper regions Srinivasalu et al 2005Srinivasalu et al , 2007Srinivasalu et al , 2008. This study is the first to report on the geochemical aspects of tsunami deposits in continental shelf region of SE coast of India.…”

A study was made on samples from one core collected immediately after the December 2004 Asian tsunami to know the geochemical nature of the offshore tsunami sediments. The core sample was analyzed for sediment grain size, CaCO 3 , organic carbon (OC) and major elements (SiO O 5 , MnO). The results indicate that the core sample can be divided into two parts: (1) upper 0-25 cm, interpreted to be deposited after tsunami (AT), and (2) lower 25-45 cm, interpreted as before tsunami (BT) as evidenced by the sandy nature AT with fluctuating CaCO 3 contents. The AT part is devoid of OC suggesting that the sediment could have been transported to deeper regions along with the finer particles. Major elements such as SiO 2 , TiO 2 , CaO indicate high values than the other elements in AT part than in the BT part. The BT part contains Al rich alluvium mud associated with finer mud and organic particles. An analysis of the correlation matrix indicates the possible source of elements and transport of heavy minerals in the AT part than the BT part. The overall results suggest that the sediments could possibly have two different origins.

“…These landward thinning deposits are distinguished on the basis of heavy mineral laminations, very fine laminations, rip-up clasts, mud drapes, an erosional base, and a sharp contact with the underlying beach sand or soil (Bahlburg & Weiss, 2007;Srinivasalu et al, 2007). In some cases, the tsunami sand deposits on the Tamil Nadu coast exhibit a set of lithotypes, indicating types of transportation mechanisms (Table III).…”

Geoarchaeological evidence of a Chola‐period tsunami from an ancient port at Kaveripattinam on the southeastern coast of India

Literature of the ancient Chola Dynasty (A.D. 9th-11th centuries) of South India and recent archaeological excavations allude to a sea flood that crippled the ancient port at Kaveripattinam, a trading hub for Southeast Asia, and probably affected the entire South Indian coast, analogous to the 2004 Indian Ocean tsunami impact. We present sedimentary evidence from an archaeological site to validate the textual references to this early medieval event. A sandy layer showing bed forms representing high-energy conditions, possibly generated by a seaborne wave, was identified at the Kaveripattinam coast of Tamil Nadu, South India. Its sedimentary characteristics include hummocky cross-stratification, convolute lamination with heavy minerals, rip-up clasts, an erosional contact with the underlying mud bed, and a landward thinning geometry. Admixed with 1000-year-old Chola period artifacts, it provided an optically stimulated luminescence age of 1091 Ϯ 66 yr and a thermoluminescence age of 993 Ϯ 73 yr for the embedded pottery sherds. The dates of these proxies converge around 1000 yr B.P., correlative of an ancient tsunami reported from elsewhere along the Indian Ocean coasts.
