Earlier quoted context omitted.

Subterranean rivers of fire is pretty close to how we understand them today.

River of fire comes out of the ground. Hmm. Where did it come from?

There must be a real hellhole down there...

They say it could have been caused by an asteroid, but don't explain why this theory is seemingly discarded. Edit: 2min of googling and I find a not very well know 20km impact crater dated at exactly the right time (mid 15th century): https://en.m.wikipedia.org/wiki/Mahuika_crater

You'll notice that Wikipedia includes it in: https://en.m.wikipedia.org/wiki/List_of_unconfirmed_impact_c...

it's existence/size/effects is controversial to say the least, TV shows about it show up on the History channel along with all the ancient aliens crap

I doubt that impacts would inject as much sulfate as was observed in the ice cores.

> they estimated that Kuwae’s eruption had released vast quantities of magma, enough to fill the Empire State Building 37 million times over This is a unit of journalistic measurement I have never come across before.

I agree, I thought the Olympic swimming pool was the only unit of measure for journalism.

Apparently the volume of the ESB is about 1e6 m³. So that's about 37e12 m³ of magma. But yeah, using a weird unit of measurement no one even knows and using 37 million as a factor pretty much guarantees that no one can relate this to anything.

Enough to completely fill the Grand Canyon(4.17T m³[1])almost 9 times over.

I think you (or the journalist) are off by a few zeros. According to wikipedia it's 32-39km^3 and I think km^3 = 1e9m^3

In the UK, they used to use the volume of Wembley Stadium (a well-known sports ground), but then it was demolished and rebuilt.

Mighty interesting, sure. Still, I can't stand these awe-driven narratives. The formula is getting old and in the jumping from one wow to the next a lot of the real questions and facts are left half-explained. And as somebody already pointed out, the units... football fields, Hiroshima bombs and the area of California... they should standardize those already, right? Journalists could use abbreviations and the rest of us would get to write unit converters when learning a new programming language.

Right. I could probably rewrite it in about five sentences, plus footnotes ;)

So New Wembley units vs Old Wimbleys?
