Au coeur des volcans: Requiem pour Katia et Maurice Krafft

SYNOPSIS

On 3 June 1991 at 3.18pm, a pyroclastic flow erupted from Mount Unzen in Japan. A cloud of superheated gases and particles descended at more than 100 mph from the peak of the volcano, consuming everything in its path. It instantly killed Katia and Maurice Krafft, volcanologists and film-makers from the Alsace region in France. They were too close. They were almost always too close.
