answer to your 4 question on reunion island (Thomas)
We have 2 volcanoes : one of them is active the "piton de la Fournaise" but its not dangerous because it's an effusive volcano. The other the one the "piton des Neige" it's because of it that our island exist, but this volcano it's asleep and it's a good thing because if it erupt we would die because it's an explosive volcano.
If you want to listen to music of Reunion:
Some old song: "mette sirop"of Srjo
New song: "2 saisons" of Pix'L
At Reunion, we have a lot of typical dishes, for exemple: "cari poulet" "rougail saucisse" "zourite"...
Personnaly my favourite holidays it's chritsmas because here, the 24 of december we party until midnight, then we open our present.
No, I don't know any funny tradition but their is many superstition, for exemple my grandmother told me not to count the stars or I will get warts.
