Plus, inside the pipe, there is no wind to stoke the ember.
Some of the houses in the photos have nothing left but ashes. Did the refrigerator melt?? Stainless steel has a melting point of 2500 deg. F. Clay bricks will crumble to ash at 2000 deg. F, yet many houses saw only the brick chimneys survive. It takes time to melt metal even at very high temps. So what is fueling the fire to make it hot enough long enough to melt metal and crumble the stucco walls?

Saw one video of a car, rather what’s left of it, melted metal on the ground… now that’s hot.
