The phrasal verb "descend on" is more commonly used in informal contexts, although it might appear in formal writing or speech, particularly in descriptive or narrative contexts. It is typically used to describe a situation where people or things arrive suddenly and in large numbers at a certain place, often causing a sense of overwhelming the location. For example, "Tourists descend on the town every summer." It can also convey a sense of an organized or spontaneous gathering, sometimes with negative connotations when implying an invasion or unwanted influx. Despite its usage in both forms, it's more frequently encountered in informal speech, such as conversations or storytelling. It's especially common in news reports or narratives that involve large-scale gatherings or movements.
