What happened to create these cuts on this person?

A recent thread made me look up “eschar” and I stumbled upon the following picture. I don’t understand what would create these cuts in someone’s body. The place where I found it and Google image did not have much information. Would anyone be able to offer an educated guess about what could cause this?
Before you look, know that it’s a very gruesome picture.

Seriously don’t click on this even if you’re not that squeamish.

That’s a burn victim under general anesthesia with a sterile surgical field around him. The cuts are surgical, straight scalpel lines, for an escharatomy.

When doing a Google image search, click on the picture, and when the options open up, you can click on the option to visit the site the picture came from. When you do that, you get this site that I’ll spoiler: [spoiler]LITFL • Life in the Fast Lane It gives the rundown on the procedure, why to do it, when, and how.

Ah, so they do this because severely burned skin isn’t elastic enough to allow his torso to inflate so he’d eventually suffocate?

I clicked on that link but for some reason, the page wouldn’t load. Your link did it, though. Thanks.
