Geologist Carolina Muñoz-Saez is in the business of hydrothermal systems. Her specialty: studying natural plumbing networks that circulate hot water underground, and occasionally erupt above it. These drive the geysers and hot springs of Yellowstone National Park. In other locations, they provide energy for electricity generation or heating. Some host unique microbial life forms. And, under the right conditions, circulating waters may pick up gold, copper or other valuable commodities from surrounding rocks, and concentrate them; many of the world’s most productive mines are the giant dried-up remains of onetime hydrothermal systems.

Steamboat Geyser in Yellowstone National Park began a new period of heightened activity in March 2018. It’s had more than 100 major eruptions since then. Scientists want to know why.

Steamboat Geyser is located on an open, sloping hillside in the northwest quadrant of Yellowstone National Park in the U.S. state of Wyoming. Yellowstone is famous for producing two ancient supervolcanoes, and for its many geysers, hot springs, mudpots, and fumaroles (gas vents) today. On March 15, 2018, Steamboat Geyser erupted for the first time in more than three years. In the three years since, the geyser has had more than 100 major eruptions, blasting water high into the air. Scientists want to understand what triggered this new p

Social media is rife with unsubstantiated claims and conspiracies about the supervolcano - claims the USGS has been diligently debunking.
One person tweeted: How am I supposed to get ready for work tomorrow knowing full well that Yellowstone is overdue for a massive explosion and the magnetic poles will flip someday?
Another person said: Keep in mind the worlds largest volcano is about overdue. Every 600,000 years, Yellowstone goes off. It could seriously impact all life on Earth. Also, the magnetic poles have started to flip.
And a third person said: Uhhh Yellowstone is most definitely overdue to erupt, by over 60,000 years.
