Scientists developed a new way to measure the rate of recharge of the Yellowstone suprevolcano
New way to measure magma beneath Yellowstone supervolcano - science news - earth

Science is constantly trying to find better ways to measure how fast magma is recharging beneath the Yellowstone supervolcano. Recently a new method was developed and it allows scientists to better understand how this process works. The researchers added deuterium (a stable hydrogen isotope) to several hot springs in the Yellowstone National Park. Then, they measured the temperatures in the springs and the time needed for deuterium to return to basal levels to calculate the amount of water and heat flowing out of the springs. Finally, they were able to estimate the amount of magma entering the supervolcano from the mantle. The last major eruption of the Yellowstone occurred 640.000 years ago and presently there is no way to estimate when the next one will happen.
