Does the volcanic activity lot trait actually DO anything?

I enjoy the volcano eruptions. They happen frequently and the bigger eruptions startle me almost every single time. There are different levels of eruptions that sometimes break everything on the lot. I am doing a rags to riches with a conservationist sim sent to evaluate the volcanic activity on the islands. My sim would get more and more stressed the longer she was there. It added an urgency to get her moved to a safer location.
