Hello, I'm Bonadea. I noticed that you made one or more changes to an article, Rock burst, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. bonadea contributions talk 14:09, 31 May 2018 (UTC)
