Yellowstone National Park Volcano Eruption Could Happen Soon: 'Anonymous' Shares Video Showing 'Bulge' Growing Beneath The Ground

A TikTok video claiming to show fresh ground movement inside Yellowstone National Park has triggered a wave of online speculation about whether the supervolcano might be edging toward eruption. The footage, posted by an unnamed user, appears to show a section of terrain rising within the park's caldera, prompting social media users to warn that the bulge could signal geological unrest.

The clip quickly circulated across platforms, with some viewers drawing comparisons to historic depictions of magma uplift before major volcanic events. Others questioned its authenticity, noting that the video lacked metadata, geological context or confirmation from official monitoring agencies.

Scientists have since urged caution, stressing that available monitoring data does not indicate unusual behaviour. The Yellowstone Volcano Observatory (YVO), operated by the US Geological Survey (USGS), continues to track the site using GPS units, tiltmeters, seismic sensors and satellite imaging, and says instruments would detect meaningful changes long before any eruption.

Social Media Reaction

The video, posted by TikTok user @unexplainedmys, shows uneven ground movement at an unspecified location in the park. Many viewers interpreted the rise as evidence of magma pushing upward, referencing the site's explosive geological history. Others were more sceptical, suggesting the clip could be misinterpreted without geophysical analysis or identified filming location.

The conversation grew rapidly across TikTok, YouTube and Reddit, where users debated whether the visuals represented new volcanic activity, a natural thermal process or even digital manipulation. Some commenters noted that previous viral Yellowstone clips had later been debunked, yet still influenced online narratives and public perception, demonstrating how easily speculative content can amplify anxieties during periods of heightened interest.

Monitoring Data and Scientific Assessment

According to the YVO's latest public bulletin, Yellowstone recorded around 180 earthquakes in October 2025, the largest measuring magnitude 3.7. Volcanologists say this level of seismicity is normal for the region, which frequently experiences small earthquake swarms.

Data also shows that Yellowstone has been slowly subsiding since 2015, following several years of mild seasonal uplift. Researchers attribute these long-term movements to cooling volcanic rock or changes in hydrothermal systems, not to fresh magma intrusion.

Experts emphasise that Yellowstone's last major eruption occurred roughly 640,000 years ago, while smaller lava eruptions happened tens of thousands of years ago. They note that the probability of a large eruption in the near future remains low. If an eruption were developing, scientists would expect sustained uplift, increased seismic swarms, chemical changes in geyser systems and other measurable indicators. None of these indicators are present.

Expert Perspective

Volcanologists say the incident highlights how visually striking online content can drive speculation without supporting evidence. A short, context-free clip can be misread as a warning sign, particularly given public familiarity with dramatic portrayals of Yellowstone in documentaries and disaster fiction.

The USGS continues to release clear updates to counter misinformation, stressing that current readings point to routine geological processes. While Yellowstone remains scientifically active and closely watched, experts say its ongoing deformation falls within expected patterns and does not suggest an imminent eruption.

Researchers advise that claims of volcanic danger should rely on instrument data and peer-reviewed analysis, rather than unverified viral footage. For now, Yellowstone's behaviour remains stable, and officials have issued no alerts.
