Sink-hole is a cut-up (a work made up of elements taken from one or more other works and rearranged to form a different text) from the book Niragongo by the vulcanologist Haroun Tazieff.

Beyond the description of an apocalyptic exploration, Haroun Tazieff's account reveals a mystical and carnal relationship with the land, at times delicate, at times violent, almost transcendental. Like Robinson's erotic experience of nature in Michel Tournier's Vendredi ou les Limbes du Pacifique, Haroun Tazieff bears witness to its raw, sensual bewitchment. Never named, sometimes personified, the designated entity and source of fantasies is shifting in genre. This rearrangement of texts and images, stripped of its scientific context, allows the construction of a new poetic-erotic narrative.
