The Yellowstone supervolcano has erupted several times in the last 2 million years or so and while the chances of an imminent eruption are currently slim, there's every possibility that it could happen again.

As such, understanding as much as possible about Yellowstone and what lies beneath it has long been a priority for scientists.

Most recently, a new study by a team of researchers from China has found that the supervolcano's magma system is fed not by a single large pool of molten rock, but by a widespread region of partially molten material - often referred to as 'magma mush' - located within the Earth's crust.This mush-like material may extend across a broad area beneath the park itself.

Despite its somewhat unassuming nature, this magma mush plays a crucial role in how the volcanic system behaves.

Rather than building pressure in a single underground chamber, magma can move, accumulate and evolve across this sponge-like network, making the system far more complex - and potentially harder to predict - than once thought.

What does this mean for a potential supervolcano eruption? As things stand, it doesn't really change the odds, but it does show just how much we still have to learn about what lies beneath the park.

Even today, researchers continue to monitor subtle signs such as ground deformation, earthquake activity and gas emissions in an effort to better understand the supervolcano's inner workings.
