It seems like you might be missing a piece of the puzzle! Your question is asking about the impact of an eruption on volcanoes, but you haven't specified which eruption.

To answer your question, I need more information:

* What eruption are you referring to? Please tell me the name of the volcano or the specific eruption you're interested in.

* What kind of impact are you looking for? Are you interested in the impact on the volcano itself (e.g., changes in shape, increased activity), or the impact on other volcanoes (e.g., triggering eruptions elsewhere)?

Once you provide these details, I can give you a much more informative and helpful answer.
