This article, titled, "Quake split a tectonic plate in two, and geologists are shaken," talks about how an earthquake back in 2017 that took place in Mexico was actually the result of the complete breakage of the tectonic plate that extended 47 miles down. This is virtually unheard of because usually at that depth the plate is hot enough to be more plastic rather than brittle. There are a few theories discussed in the article of why this deep breakage occurred, (i.e. water v.s. dehydration) so feel free to read more on that! But the reason I chose this article was because our reading said that, "Intense geologic activity occurs at plate boundaries where plates move away from one another, past one another, or toward one another." This article gives a very specific exception to this. A full break in a plate is an intense geologic event that didn't happen at a plate boundary. Sometimes what we think is or isn't possible happens anyway!
