Having been lucky enough to stay for five weeks on the island of La Réunion, I offer a few articles, illustrated with recent photos, on "the intense island", interspersed with others on volcanic news.
But first of all, a small reminder concerning the formation of the island.

Located 700 km. to the east of Madagascar, the island of Réunion is entirely of volcanic origin. It consists of an intraplaque massif, due to a rise of deep magma piercing the African plate: "a hot spot". The accumulation of eruptive products on the ocean bottom, at less than 4,000 meters, ended up creating an island of elliptical shape, 70 km. on 50, extended NO-SE., with an area of 2.512 km².
It consists of two volcanoes, dividing the surface 2/3 -1/3.
- Piton des Neiges, north-west, today asleep, for 2/3, and
- Piton de La Fournaise, in the south-west, in activity.
