No, that is not an onomatopoeia. That's more personification. Onomatopoeias are usually the sound the object makes. For example, "buzz!" is an onomatopoeia of a bee or a bug. You could phrase your sentence like this instead: "Crash!! The meteoroids slammed against the earth's surface." In this sentence, "crash!" would be the onomatopoeia.
