A seven-mile caldera would surely be a 'major eruption'. Lots of distance between a small mountain (439 ft tall, isn't that a hill?) and a large volcano (Vesuvius is for instance the size of Naples).

I think what he's asking is how one would know whether the entire caldera was at risk or whether there was just a risk of a small eruption, such as in the 16th century. I'm guessing the answer is that "they don't".
