This is a little video clip about the vulcano Unzen in japan, that has eruption in 1991.

In June 1991, while Katia and Maurice Krafft where filming eruptions at Mount Unzen, they were caught in a pyroclastic flow which unexpectedly swept out of a channel others had been flowing down and onto the ridge they were standing on. They were killed instantly, along with 41 journalists also covering the eruptions.
