Centuries of warning of a supervolcano eruption - with zoomable map of top seven supervolcanoes

A study at the universe of Illionois shows that it would take anywhere from centuries to thousands of years for a magma chamber to change enough to permit a supervolcano. Our potential supervolcanoes aer all monitored by volcanologists and none of them show any signs of this process. We would have plenty of warning because the ground would be lifted not just by meters but by tens to hundreds of meters before the eruption. The study found that this process would most likely take many of our human lifetimes, according to a study at the University of Illinois ""When new magma starts to rejuvenate a supervolcano system, we can expect to see massive uplift, faulting and earthquake activity," Gregg said. "Far greater than the meter-scale events we have seen in recent time. We are talking on the range of tens to hundreds of meters of uplift. Even then, our models predict that the system would inflate for hundreds to thousands of years before we witness catastrophic eruption."

“People need to keep in mind that sites like Yellowstone are very well-monitored,” Cabaniss said. “It is also important to note that our research suggests that the whole rejuvenation-to-eruption process will take place over several or more human lifetimes. Our models indicate that there should be plenty of warning.”"

So, none of these are likely to erupt in the next few centuries because we haven’t seen the build up for an eruption.

Where can we expect the next supervolcano?
Although there are no signs of supervolcano eruptions anywhere in the world yet, it’s going to happen eventually. World wide, you get between 22 and 1.4 eruptions every million years (rather variable). So, some time within the next few tens of thousands of years to a million years, we can expect a super volcano eruption. Yellowstone isn’t the only supervolcano in the world. The top ones are shown on this map:  Long Valley Caldera~Long Valley Caldera, California~Not likely to erupt ~ ~ ~ Long Valley Caldera Valles Caldera~Valles Caldera, New Mexico~Not likely to erupt ~ ~ ~ Valles Caldera Yellowstone Caldera~Yellowstone Caldera, Wyoming~Not likely to erupt in our lifetimes - probably won’t erupt for 1000 years or more, last one 640,000 years go. ~ ~ ~    Yellowstone Lake Toba~Lake Toba, Indonesia~Erupted 73,000 years ago - largest super volcano eruption for 2.8 million years, caused a “Volcanic winter” worldwide for 6 years. But no activity in recent times, not likely to erupt. ~ ~ ~Lake Toba Taupo~Taupo, New Zealand~Last super eruption 26,500 years ago, could do so again ~ ~  ~Taupo Campi Flegrei~Campi Flegrei, Italy~ Magma chamber active, not about to erupt but could be prelude.

 * 1) Yellowstone Caldera, Wyoming - probably won’t erupt for 1000 years or more, last one 640,000 years go.
 * 2) Long Valley Caldera, California - not likely to erupt
 * 3) Valles Caldera, New Mexico - not likely to erupt
 * 4) Lake Toba, Indonesia - erupted 73,000 years ago - largest super volcano eruption for 2.8 million years, caused a “Volcanic winter” worldwide for 6 years. But no activity in recent times, not likely to erupt.
 * 5) Taupo, New Zealand - last super eruption 26,500 years ago, could do so again
 * 6) Campi Flegrei, Italy -Magma chamber is active, could be a prelude to an eruption. So this is a candidate. Especially dangerous as it is close to Naples, so many people would need to be evacuated and at risk from it.
 * 7) Aira caldera, Japan - is now erupting through Mount Sakurajima, - and not able to go supervolcano
