Does the volcanic activity lot trait actually DO anything?

I haven’t had it happen yet either and I’ve lived with it for a full sim week. I put it on the island lot near the volcano. I don’t know if it doesn’t work correctly on that lot or what but I have yet to see anything. I’m hoping it’s just taking a while. I was watching sim supply today and it’s happened to him multiple times already. Of course he is playing on the lot that automatically has the trait. I don’t know if that makes a difference or not.
