Our advice is to go out and start some fires, learn how fire works. None of what you wrote makes even the faintest amount of sense. Fires have a huge dependency on certain things:

1. Wind
2. How close the next set of fuel is (in your nieghborhood photo, the next seet of houses has a nice distance from the burnt set, distances get shorter with wind, but perhaps no wind that day?)
3. type of fuel: if you knew ANYTHING about fire, you'd know a tree with green leaves that's not a pine, has about as much chance of burning as ZERO. You can practically grow one inside of a giant fire. A green non-evergreen tree is LOADED with water, water don't burn.
4. structure. the tree you say is "burning inside out" is a hollow tree, it's IDEAL for fire, as ideal as a wooden skyscraper (which is how all of San Fran went down)

You know exactly NOTHING about fire, and it's clear from this post. Again, not trying to be a GIANT dick (just a bit of a prick), but you really need to get outside, get some sunburn and some beta rays from a fire you make yourself. If you practise burning stumps, for instance, you'll actually learn something so when you read all the consipracy-theory articles you'll know better which ones might have some merit, and which ones are written by pasty-white teenagers with no friends in a damp mold-spore filled basement on a hidden beyond-Antarctica island called Fatlantis.
