It is my pleasure Mma Tortue,
Best wishes from Kiel Germany.
for english speaking folks who wish to get informed about tsunamis, google may provide good reference. just search for tsunami.
many national maritime offices and national weather orgs provide detailed info.
as for Mauritius the december tsunami produced a high tide that was 1.5 meters higher than usual flooding some beaches and a few streets on east coast but there was no "wall of water" as in SE Asia.
there is no continental shelf that would build it in such a scale for one and the reef around the island serves as wavebreaker.
still a flood occurred as the tsunami approached the island.
march 28 earthqake in sumatra did not produce a significant tsunami it seams tho perhaps there was just no data due to lack of deep sea warning system that is buoys that register changes of sealevel in the Indian Ocean.
New earthquakes around sumatra or along SE Asia or perhaps at another corner of the region may occur and so see the news before you travel.
