On the volcanoes of the world

It seems the Earth is breathing…
Its exhalations can be verified in very specific spots of the globe, wherever a volcano is active. It is precisely at that moment that Guy de Saint Cyr, a geologist full of surprises and in love with volcanoes for the past forty years, chooses to set up expeditions with small groups of neophytes.
Each trip is an opportunity for a psychic strife with the elements, an ever wild nature, often hostile, to share a strong human adventure, scientific knowledge and to cross mind-blowing landscapes.
