Nippon TV to Broadcast Tape Recovered from 1991 Eruption

Nippon Television Network plans to broadcast newly restored video footage taken by an NTV cameraman just before he was overtaken by a fast-moving pyroclastic flow of hot gas, ash and rock let loose in the 1991 eruption of Mt. Unzen, an active volcano on the southern island of Kyushu.

According to news reports in the Yomiuri and Mainichi newspapers, the six minutes of footage, including both video and audio, were discovered this past June. It was found in a hut located in an area closed to the public, and authorities were alerted to its existence with an anonymous phone call. Camera equipment from three other media companies was also found there.

The NTV footage will be broadcast just after midnight on Oct. 17 as part of a documentary called "378-Second Testament."

The Mainichi Shimbun describes the video like this:

"The footage begins with the sound of rain. At the time, the press corps was photographing approximately four kilometers from the summit. At 3:57 p.m., just before the pyroclastic flow was thought to have begun at 4:08, the camera captures a rapidly expanding cloud of black smoke. 'This is incredible,' comes a voice from the press corps. 'Volcanic ash is surrounding us. There is a sharp burning smell,' a TV reporter begins to say. 'Are you getting it on camera?' 'Yeah, I’m getting it.' And then you hear a policeman say three times, 'This is extremely dangerous. Please get out of here.' The camera captures a raincoat clad Mainichi Shimbun cameraman (the late Tsutomu Ishizu) heading towards the mountain. Then just after 4:08, the camera suddenly points to the ground and stops."

Lava first started emerging from Mt. Unzen in May 1991 and the Japanese government took steps to evacuate local villagers. But tragedy ensued when a sudden pyroclastic flow on June 3 shot out 4.5 kilometers from the crater, burning 180 houses and claiming the lives of 43 reporters, film crew members and scientists observing the eruption.

Notes University of California, Davis geology Professor Richard Cowen:

"Three volcanologists were killed: Maurice and Katia Krafft, who had produced spectacular films and books on volcanoes, often by risking their lives very close to eruptions; and Harry Glicken, an American expert on Mt. St. Helens, who would have been sensitively aware of the dangers of pyroclastic flows. Glicken had in fact the week before compared Mt. Unzen with Mt. Pele, the dangerous volcano on Martinique. It is clear that most of the people killed understood the danger, and chose to accept it. They were in the evacuated 'forbidden zone' when they were killed."

The camera belonged to the late Koji Kobayashi, then 26. The camera was destroyed in the explosion, even the inside filling with volcanic ash. Despite being deformed by the heat, some 70 percent of the exposed video and all of the audio were restored.

NTV has shown the footage to the survivors and obtained their permission to release it. It says it is releasing the footage in the hopes that it might help prevent a similar tragedy in the future.
