    Although I was able to answer because I'm familiar with the modeling notation that appears to be used, it's standard practice to indicate the modeling language used. If a standard modeling notation is used, it's pretty straightforward to obtain documentation on that notation. However, if it's a non-standard notation, the author needs to provide information on what colors and symbols mean somewhere.

On an ArchiMate 3.1 diagram, those symbols are "Application Events". Application events represent changes in application state. You can find more information in the ArchiMate 3.1 specification, specifically in Chapter 9 Application Layer.
