Boxing Day 2004 Tsunami
Impact of the Boxing Day 2004 Tsunami
UNEP National Rapid Environmental Assessment of the Tsunami impact on Seychelles.

Executive Summary:
"Two major patterns in coral reef damage were noted, controlled by the geographic location of each island and exposure direction of each site, and reef substrate. The northern islands clustered around Praslin (including Curieuse, La Digue, Felicite and the rocks of Isle Coco and St. Pierre) showed very high levels of damage (approaching 100%) on carbonate reef substrates. By contrast, sites around Mahe showed much lower levels of impact, generally below 10%. The limited damage on Mahe is due to the shelter provided by the outer northern islands and dissipation of wave energy as the tsunami traveled over the greater distance of shallow water from the outer edge of the banks to Mahe."
