Volcanic unrest at Lake Taupō in New Zealand could continue for months without any real eruption but could cause landslides, mudflows and ground subsidence.
The lakebed of Lake Taupō, which sits in the caldera of a supervolcano, is shifting in various places due to the volcano's magma.
Volcanologist Colin Wilson says the findings "change the way we think about the massive Yellowstone explosions."
Analysis suggests Steamboat has a "more complex and deeper" plumbing system than Old Faithful.
"We often hear about the potential for large volcanic eruptions of the Yellowstone volcano. However, we rarely focus on the threat of large earthquakes in the region," researcher Jamie Farrell said.
"Knowing this will help us understand supereruptions that have occurred before, and those that will occur in the future."
Scientists analyzed radioactive decay of potassium to argon to learn more about Yellowstone's eruptive history.
A supervolcano is a large volcano that has had an eruption of magnitude 8 or more
Yellowstone's last major eruption took place around 640,000 years ago, producing a blast that ejected more than 2,000 times the amount of ash spewed out by Mount St. Helens in 1980.
"I think we are moving beyond a cartoon stage of understanding now."
A recent study further unravels the mystery of Yellowstone's volcanic system.
"Man, the changes would be so much bigger than anything we've ever seen."
Nibiru is not going to destroy the world, and these three possibilities are not likely to either.
The earthquake swarm began six weeks ago and is ongoing.
Earthquake swarm is currently active on the western edge of Yellowstone National Park.
The eruption risk at Yellowstone remains low, but one of the recent earthquakes was the biggest to have hit since 2014.
