Yellowstone volcano: Eruption ‘worst-case scenario’ exposed by USGS chief scientist | Science | News

“Most scientists think that the buildup preceding a catastrophic eruption would be detectable for weeks and perhaps months to years.

“Precursors to volcanic eruptions include strong earthquake swarms and rapid ground deformation and typically take place days to weeks before an actual eruption.”

Dr Poland, who spoke to CBN News, said: “With Yellowstone, the worst-case scenario is always a tremendous explosion, of the kind that last happened about 631,000 years ago.

“That was one of these super-eruptions that occur on average maybe every 50 to 100,000 years somewhere on the planet.”

He added: “These sorts of eruptions would be immediately devastating to everything around them out to a radius of hundreds to thousands of kilometres.”
