Here's one scientist saying that while that logic kinda works for earthquakes volcanoes don't behave that way. https://www.livescience.com/yellowstone-caldera-supervolcano-eruption https://www.livescience.com/yellowstone-caldera-supervolcano... Also, even if it would be possible to compute that an earthquake/eruption is overdue I've yet to see it done correctly. Obviously I don't know where the person I'm replying to got their statistic. But if you Google something like "Yellowstone overdue" the results use very poor logic, often just extrapolating from three data points millions of years ago.
