From the original BBC article: > Yellowstone currently leaks about 60-70% of the heat coming up from below into the atmosphere, via water which seeps into the magma chamber through cracks. The remainder builds up inside the magma, enabling it to dissolve more and more volatile gases and surrounding rocks. Once this heat reaches a certain threshold, then an explosive eruption is inevitable. > But if more of the heat could be extracted, then the supervolcano would never erupt. Nasa estimates that if a 35% increase in heat transfer could be achieved from its magma chamber, Yellowstone would no longer pose a threat. The only question is how? So, two or three GW of heat loss should be sufficient to keep the magma chamber from heating any further if NASA's estimates are accurate.
