Scientists from the Ha Noi-based Institute of Geophysics said yesterday they had found signs that at least three tsunamis had struck the coastal province of Nghe An Province in ancient times.
The tsunamis were thought to have occurred 4,500-4,300, 4,100-3,900 and 900-600 years ago.
Assistant professor Cao Dinh Trieu said scientists found banks of placura placenta-arca granosa shells (a type of mollusc) in Quynh Van, Nghi Tien, Quynh Nghia Communes and Dien Chau Town and along Nghi Yen seashore that were 4,000-4,600 years old.
Scientists said their findings suggested another tsunami could again strike the coast of Viet Nam. Trieu added that an earthquake measuring nine on the Richter scale in Manila could result in a seven-metre wave barrelling into the coast of Nghe An Province.
Studies on ancient tsunamis in Viet Nam began in 2005, with Vietnamese scientists collaborating with experts from Russia.
