Yellowstone volcano's last three big eruptions went off about 640,000, 1.3 million and 2.1 million years ago. And although there is no evidence the supervolcano in the northwest corner of the US erupts like clockwork, many people fear Yellowstone is way overdue another blast. Social media is rife with rumours and claims 2020 would be the perfect year to end with a supervolcanic eruption.
One Twitter user said: "So Yellowstone might erupt and kill half or more of the US, so is there anything you always wanted to tell me?"
Another person said: "I haven't been able to sleep peacefully since seventh grade when Mr. Keopke planted the thought in my mind that the Yellowstone supervolcano could erupt + kill us all."
And a third person said: "IDK what Tik Tok I'm on... but why does no one talk about the fact that the Yellowstone volcano is 30,000 years overdue to erupt and we'd die."
The concerns come as the US Geological Service (USGS), which monitors the Yellowstone caldera for activity, has published its monthly activity report for the Yellowstone area.
