Earthquakes in the Yellowstone volcano region have prompted concerns the supervolcano is brewing towards another eruption. Although scientists are certain Yellowstone will not erupt within our lifetime, many still fear a cataclysmic blast. One person on Twitter said: "God help us if these recent swarms of quakes around Idaho and Utah are harbingers of a Yellowstone Super Volcano eruption."

Another person said: "Agreed. Don’t think it will be a full eruption of Yellowstone (hopefully) but it’s looking like that area is heating up.

"Combined with everything else going on, it would be a total societal collapse.

"Based on the behaviour now over a <2% mortality rate it’s not gonna be pretty."

And a third Twitter user said: "Yellowstone earthquake. 2020 is gonna see a volcanic eruption."
