PREHISTRICAL AND HISTORICAL TSUNAMIS OF RYUKYU ISLANDS ESTIMATED THGROUGH TSUNAMI DEPOSITS

Abstract

 The Meiwa tsunami is well known around the world due to the extensive research done in this area. However researchers, Kawana and Nakata and others, suggested that there might have been a larger tsunami before the Meiwa tsunami according to research done on the age of the Tsunami-Ishi. Contrary to the existing explanations on pre-historical tsunamis in the Ryukyu Islands, this research discloses that there are no profound or consistent traces of other tsunamis occurring in the region other then the Meiwa Tsunami.
