I can't create a summary of this article because I don't have access to its content. The search results contain information about the July 2025 Kamchatka earthquake itself, but not the text of the scientific article from the journal Science entitled "Simple unilateral rupture of the great Mw 8.8 2025 Kamchatka earthquake" from February 2026. In order to create an accurate and factual summary according to your requirements, I would need access to the full text of this article. Without it, I could not guarantee that the summary would contain only verified facts from a specific article.
