> Where does the confidence to make this claim come from? I have no idea, but I can give you a data point from my personal experience: about ten years ago we visited Rotorua in New Zealand, which promotes its geothermal activity as a tourist attraction [1]. We were told by the locals when we were there that the geothermal activity had reduced noticeably since a geothermal power plant was installed some years prior, resulting in controversy over the wisdom of having built it. Rotorua's geothermal activity area is a lot smaller than Yellowstone, but as an anecdote it indicates that reducing the risk of eruption is not entirely implausible. --- [1] https://www.waiotapu.co.nz/ https://www.waiotapu.co.nz/
