"We watched the first red blaze appear, heard the sharp crackle, caught the gleam. example of (1 )personification (2)analogy (3) onomatopoeia
These lines contain a number of onomatopoeia. The words that I would say fit in that category are blaze, crackle, and gleam. The term means that the word sort of sounds like or suggests the thing that it means. So the word "crackle," for example, sounds like the thing it describes. The sound of the words "blaze" and "gleam" sort of suggest their ideas too -- more than "fire" and "shine" would, for example.
These are not examples of personification because fires are quite capable of doing these things -- they are not things that only animate beings do.
