Facing the Killer Volcano (continued)
The docu-drama "Facing the Killer Volcano" was released just days before the 22th anniversary of the death of Maurice and Katia Krafft. I had the opportunity to see the film premiere in 2011 at the General Assembly of the Association European Volcanological who had been allowed to project this document at this time...
The Japanese authorities have done nothing wrong, because many times, they gave the order to evacuate threatened by pyroclastic area. This is confirmed by Report No. 1540-08 relating to the eruption of Unzen as it was presented to the French National Assembly.

Although people have received advice from that time to evacuate the area, some came back to collect their belongings and their pets. Several journalists and scientists are also returned to this area to photograph and film the spectacular pyroclastic flows. Firefighters were stationed in a designated area to monitor the empty houses evacuees used by journalists. These journalists were stationed at 4 km away, in front of the casting. I warned by radio, police and the Headquarters for Measures Against Disasters of Shimabara. But the people who were on the "Recommended Zone" did not take my warnings seriously...
Despite all the admiration we may have to Katia and Maurice Krafft, it is clear that they are dead is that they have made a mistake. In addition, it is reasonable to think that if they had emptied places, other people around them would have followed.

To conclude, I think if we had given Maurice choice of his death, this is probably the option he would have chosen. He had seen so many eruptions as future were "rab" as he liked to say. "If I die tomorrow, I do not care." This is what he also says in this short video filmed at the foot of Unzen, shortly before his death:
