Katia and Maurice Krafft

Catherine Joséphine "Katia" Krafft and her husband, Maurice Paul Krafft were French volcanologists and filmmakers who died in a pyroclastic flow on Mount Unzen, Nagasaki, Japan, on 3 June 1991. The Kraffts became well known as pioneers in the filming, photographing, and recording of volcanoes, often coming within feet of lava flows. Their obituary appeared in the Bulletin of Volcanology. Since their deaths, their work has been featured in two documentary films by Werner Herzog, Into the Inferno (2016) and The Fire Within: A Requiem for Katia and Maurice Krafft (2022), and a further film, Fire of Love (2022), depicted their lives, relationship and careers using their archived footage.
