Where and When Could It Erupt?
Yellowstone National Park, located primarily in northwestern Wyoming and extending into Montana and Idaho, is home to one of the world’s most studied volcanic systems. This system has drawn the attention of geologists due to its dynamic nature and its history of supervolcanic eruptions. Recent research by the U.S. Geological Survey (USGS) and Oregon State University has provided a more detailed understanding of the magma reservoirs beneath the park.
A study led by geophysicist Ninfa Bennington used magnetotelluric measurements to image the subsurface, revealing four distinct magma bodies beneath Yellowstone. Among these, the northeastern magma body appears to retain sufficient heat to remain partially molten over the long term, making it the most likely candidate for any potential future volcanic activity.
Yellowstone’s History of Massive Eruptions
Yellowstone has experienced three major eruptions over the past 2.1 million years, each leaving behind a caldera, a massive volcanic depression formed when magma is expelled, causing the ground above to collapse. These eruptions formed what is now known as the Yellowstone Caldera, measuring approximately 30 by 45 miles (48 by 72 km).
The last of these supereruptions, the Lava Creek eruption approximately 631,000 years ago, left a landscape marked by geothermal activity, including geysers, fumaroles, and hot springs. These features are surface expressions of the vast heat reservoir beneath the park. Scientists continue to analyze these geothermal regions to track changes in subsurface conditions.
Mapping Magma Deep Underground
The research team employed magnetotelluric instruments to detect variations in electrical conductivity underground, allowing them to map the distribution of molten rock beneath Yellowstone without drilling.
Their findings indicate that rhyolitic melts are stored in segregated regions beneath the caldera, suggesting that magma is not evenly distributed but rather concentrated in specific areas. The northeastern magma body, located beneath the northeastern section of the Yellowstone Caldera, was identified as the only reservoir with long-term heat retention, making it a focal point for future monitoring efforts.
A schematic map of Yellowstone’s volcanic structure highlights several key geothermal areas:
- Lower Geyser Basin (LGB)
- Norris Geyser Basin (NGB)
- Hot Springs Basin (HSB)
These basins are surface indicators of the heat below and align with the mapped locations of magma reservoirs.
The Northeastern Magma Body
While the presence of four distinct magma bodies was confirmed, only the northeastern sector appears to retain enough heat to remain partially molten long-term. This refines previous models that considered multiple regions as potential future eruption sites.
Bennington and her team noted, “We suggest that the locus of future rhyolitic volcanism has shifted to northeast Yellowstone Caldera.” This statement pinpoints a specific area for continued geological research and hazard assessments.
While no immediate threat exists, understanding where magma is accumulating provides valuable insight into how Yellowstone’s volcanic system evolves over time.
How Yellowstone Compares to Other Supervolcanoes
Yellowstone is often compared to other supervolcanoes, particularly Toba in Indonesia, which last erupted 74,000 years ago. This eruption led to significant global climatic impacts, including a volcanic winter. Studying supervolcanic activity worldwide helps geologists determine common patterns in magma accumulation and eruption timing.
Comparisons with Toba, Taupō (New Zealand), and Campi Flegrei (Italy) reveal that deeply buried magma behaves differently in each system, depending on regional geological conditions. By understanding these variations, researchers refine their ability to model and predict volcanic activity on a global scale.
Monitoring and Public Communication
The Yellowstone Volcano Observatory (YVO), a joint program between the USGS, the University of Utah, and the National Park Service, plays a key role in monitoring the park’s volcanic activity. YVO tracks several indicators of volcanic unrest, including:
- Seismic activity: Earthquakes can indicate magma movement.
- Ground deformation: Rising or sinking land may signal underground changes.
- Gas emissions: Increased sulfur dioxide levels could point to new magma intrusion.
YVO provides real-time updates to the public through its website and research bulletins, ensuring transparency and informed decision-making.
Addressing Concerns About Yellowstone’s Eruption Potential
Despite widespread speculation, geologists emphasize that a catastrophic Yellowstone eruption is extremely unlikely in the foreseeable future. Supervolcanic eruptions require very specific conditions that rarely align, and the geologic record suggests that Yellowstone is not currently moving toward such an event.
Current models show that most of the magma beneath Yellowstone is solidified or partially molten, but not in a state conducive to an eruption. Minor ground movement and hydrothermal activity are normal in a region with a deep heat source, but they do not indicate a brewing disaster.
The study is published in Nature.

“Dr Phil will be playing Oprah” — Hilarious memes erupt as Britney Spears reportedly picks Selena Gomez as her top choice for biopic
Britney Spears is focused on her biography these days, assessing the apt actress to portay her on screen. Selena Gomez and Natalie Portman are reportedly the front-runners, according to a blue-tick X post by Buzzing Pop , though the information is yet to be officially confirmed.
Britney Spears’ life in the limelight has had all the ingredients for a heady biopic, from fame and controversy to intense scrutiny, personal hardships, and a fierce fight for freedom. Fans and critics are excited alike about filmmaker Jon M. Chu’s plans to adapt Spears’ memoir, The Woman in Me, for the screen.
As the argument gains ground over who would be the perfect Britney on screen — pop queen Selena Gomez or feted actress Natalie Portman — social media, not surprisingly, has also exploded with memes and wisecracks.
A user named @roseColoredSass wrote on X:
“Next, Dr Phil will be playing Oprah .”
Dr Phil McGraw or Oprah Winfrey would perhaps dismiss that comment in jest, but the choice for Britney’s role won’t be an easy one, though. The actress in question would have to do more just mimic her dance steps or style. The essence would lie in portraying the emotional depth about pop sensation Spears.
Responses to the unconfirmed report of the choice being a toss-up between Selena Gomez and Natalie Portman has elicited diverse reactions on social media, ranging from curious to funny ones, with many expressing rather strong opinions. Let us walk you through a few responses that stand out:
Here’s how netizens have reacted as Britney Spears reportedly chose Selena Gomez or Natalie Portman as top choices for her biopic
A user identified as @ihatefakos quipped about Natalie Portman as a possible choice:
“Natalie Portman makes more sense, but how is she going to play teenage Britney?”
Another user on X (@SummertimeX5) commented:
“And who will be doing the singing, acting, and dancing?”
A user (@The Vu Viscount) wrote:
“I feel like they need to cast an unknown, this should be someone’s breakout role”
Another user (@Invincible) expressed:
“I think Selena Gomez would be perfect as Britney”
A netizen (@JT) commented:
“Britney is not Latina. So Selena shouldn’t be an option.”
Another netizen (@M) expressed:
“u want THIS to play britney’s biopic lmfao”
A user (@COWBOYREQUIEM) wrote:
“i can actually see selena emulating her very well. i can imagine the diet pepsi segment interview for example. she would do that so well. and play the real emotion of britney in the media well. i just think she will get it and truly put her mind too it. legend”
Another user (@flowers) commented:
“Natalie looks more like Britney”
A folk (@kendall) commented:
“selena – NO that doesn’t make any sense. Natalie – beautiful but too old? isn’t this based on britney when she’s in her teens”
A netizen (@benni) expressed:
“please let it be selena. just so i can laugh the entire time”
A user (@Juan Pablo Rotger) commented:
“Natalie Portman is the exact same age as Britney. Might as well play herself at that point.”
Many users felt Selena Gomez with her a youthful charm and vitality as a performer might evoke Britney’s formative years and, hence, be the ideal fit. Others feel that Natalie Portman’s range and depth would suit the role in terms of strength and complexity.
Given how complicated Britney’s life and career have been, choosing the perfect actor to play her role is certainly no a small task. Tough call for the fans, and surely tough for the casting team of the film. May be Chu and company will find the right choice in a thrid actress.
Meanwhile, the argument on social media continues.

Changes reported at Yellowstone’s volcano. Could it erupt?
Scientists are tracking changes at the giant supervolcano that lies under Yellowstone National Park, but they say there’s no need to worry at the moment.
“The western part of the Yellowstone caldera is waning,” said Ninfa Bennington, a volcano geophysicist with the U.S. Geological Survey and lead author on a paper in Wednesday’s edition of the journal Nature.
The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles.
The findings mean that the future of volcanic activity at Yellowstone is in the northeastern part of the park, and there’s no chance it’s going to blow anytime soon.
“This volcanic system is not capable of producing that sort of eruption,” Bennington said.
For now, Yellowstone’s mud pots will keep boiling, the hot springs will keep steaming, the geysers will keep spraying, the Earth will keep shaking and the fumaroles will keep venting. The massive underground pools of magma below the storied park are still red-hot, ranging between 1,247 degrees and 2,512 degrees, Bennington said.
Learning more about the magma under Yellowstone
Yellowstone is one of the planet’s largest volcanic systems, a place where a plume of the Earth’s molten core rises up through the solid rock of crust, heating and melting it to form reservoirs of magma 2½ to 30 miles below the surface.
In the past this was often pictured as a single underground lake of lava beneath volcanos, but newer mapping and imaging techniques make it possible to see the complex systems of reservoirs the magma had gathered in.
An imaging technique that produces more precise maps of the large reservoirs of magma under the park shows large pods of deep magma leading up to more shallow ones closer to the surface in the northeast, which tie into the park’s famed hydrothermal systems.
To know how likely a volcano is to erupt, vulcanologists calculate something called a melt fraction. It’s the ratio of how much magma (which they call “melt”) to the total volume of crust.
“Think of the Earth like a sponge,” Bennington said. But instead of water filling the holes and crevices, it’s molten rock. In a volcanically active area, there’s a greater proportion of magma to earth. The higher the proportion of magma, the more eruptible the area is.
The mapping was done using magnetotellurics that measure the electrical conductivity of what lies below the Earth’s surface. Melted rock, magma, is extremely good at conducting electricity, so it makes precise mapping of areas where magma is stored possible. The testing was conducted over several months by scientists from the USGS, Oregon State University and the University of Wisconsin-Madison.
What they showed was that while there are multiple enormous reservoirs of magma under Yellowstone, they’re separated from one another.
“It would be difficult to mobilize into a single eruption because they’re not connected,” Bennington said.
When will Yellowstone erupt again?
It’s still possible that the northeastern portion of the park could erupt in a massive explosive eruption similar to those that have occurred at Yellowstone in the past 2.1 million years. In those events, volcanic ash reached from the Pacific ocean to Canada to Mexico.
They tend to reoccur about every 600,000 to 800,000 years, according to the U.S. Geological Survey.
The most recent one was 640,000 years ago. It’s known as a super-eruption because it released an estimated 250 cubic miles of material – 1,000 times larger than the Mount St. Helens eruption in Washington state in 1980.
For now, the spaces in the sponge aren’t full enough of magma to support an eruption. For that to happen, the system would need more magma to fill more spaces in the crust’s “sponge.” Once the system got to some crucial fraction of those spaces filled with magma, it could cause an eruption.
“But we’re not nearly there now,” Bennington said. “We’re talking geological time scale.”
That’s hundreds of thousands of years – and possibly much longer.
Yellowstone National Park’s supervolcano has been making headlines recently due to reported changes in its behavior. Scientists have observed an increase in seismic activity, as well as rising ground temperatures and increased gas emissions.While these signs are concerning, experts are quick to point out that these changes do not necessarily mean an eruption is imminent. Yellowstone’s volcano is one of the most closely monitored in the world, and scientists are constantly monitoring its activity to ensure the safety of the park and surrounding areas.
Despite the increased activity, the likelihood of a catastrophic eruption at Yellowstone is still considered to be low. The last major eruption occurred over 640,000 years ago, and the volcano is not showing any signs of an impending eruption at this time.
However, it is always important to stay informed and prepared for any potential changes in Yellowstone’s volcano. Visitors to the park should follow any safety guidelines issued by park officials and be aware of any updates on the volcano’s activity.
While the possibility of an eruption is always a concern when dealing with a supervolcano like Yellowstone, it is important to remember that the chances of a catastrophic event are still relatively low. Scientists will continue to monitor the volcano closely and provide updates on any changes in its behavior.
