Research Abstract

We took drilling core samples at some locations from southwest to east coasts of Sri Lanka to estimate the recurrence interval of large tsunamis in the Indian Ocean. Possible tsunami sand layers intercalated in the peat layer in each core. Our study revealed that the possible tsunami layers were deposited every 600-1000 years interval in the 7000 years sedimentary record. The distribution of the tsunami deposits can be explained by the numerical modeling results.
