there is a poignant set of images taken by a photographer Robert Landsburg who chose to post himself too close to the blow up of the top of Mount Saint Helens in 1980.

the last picture from his salvaged camera is similar to what we see for this topic: https://allthatsinteresting.com/wordpress/wp-content/uploads... his camera was found under this body, with speculation that he was protecting it, which doesn't seem unlikely, but it also would not be surprising for him not to have had that presence of mind, things were happening very quickly.

From that article:

After taking his final photograph, Landsburg removed the roll of film from his camera and placed it in a canister. He buried the camera and the film canister deep in his backpack. Then, he placed the backpack on the seat next to him and covered it with his body.

It was more than just jumping on top of his camera. Sounds like there’s some confidence about his intention.
