Seychelles being a small island nation surrounded by the Indian Ocean remains vulnerable to the effects of climate change. One clearly visible sign of such vulnerability lies on the archipelago’s coastlines where several shorelines have been subjected to intense degradation and erosion.
A new study on the frequency of past giant earthquakes in the Indian Ocean region shows that Sri Lanka, and much of the Indian Ocean, is affected by large tsunamis at highly variable intervals, from a few hundred to more than 1,000 years.
