Abstract: | Four short core samples were collected from the creek, estuarine regions of southeast (SE) coast of India affected by the
2004 Asian Tsunami. The study is aimed to signify the importance of ostracoda species in identifying major natural events
(e.g. Tsunamis) in the coastal regions. The presence of many marine ostracoda species in the beach areas and the comparative
studies with earlier reports from SE coast indicate that these species were brought by the high-energy tsunami waves. The
depositional feature of ostracoda species in the beach and estuarine region also infers on the nature and force of tsunami
waves in a particular region. The results clearly support that microfossils can be used to identify the major natural events
close to coastal regions. |
