"A smaller but still sizable eruption was observed at the supervolcano in 1538. That event lasted eight days and created the mountain Monte Nuovo. But since then, the volcano has been quiet, slumbering for more than 500 years."
I'm going to assume it's 1538 AD and that this volcano has slumbered almost 500 years. And if create a "new mountain" was enough to relieve the pressure then, how do they distinguish a major eruption from a minor one when performing these forecasts?
- JoeAltmaier 10y agoA 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).
- chakalakasp 10y agoI 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".
