China fears: Scientists warn volcano extinct for 500,000 years 'appears to be recharging'

The last eruption at the site was in 1776, but a study led by Ji Gao – published in the journal Geology last month – says there may be activity taking place under Weishan.

The team created a 3D map showing the structure beneath, apparently identifying two magma pockets.

Previously, scientists had identified a shallow magma chamber beneath the volcano.

In the latest study, the team found this shallow chamber in the upper crust, along with another deeper down, in the middle crust.

Researchers say the findings are consistent with models suggesting the magma in the middle crust may be serving as a source to "recharge the magma chamber in the upper crust."

This is in the far NE of China, about 100 miles SW of the border with Russia and about 200 miles north of the Chinese city of Harbin and a bit over 300 miles north of Changchun (i.e. significant industrial cities). But if this volcano goes Mt. St. Helens the effects will not be localized to NE China.

If a volcano is extinct, it is impossible to recharge.

In either case, someone is lying.

Nah, "extinct" probably should almost never be used, simply because it's a claim to knowledge we humans usually don't, and really almost can't, have. Admitting to limited knowledge doesn't come easily to many scientists, it threatens their pride.

Well...first the virus, then the flood, earthquakes, and now potentially a volcano ....

I didn't realize 1776 was 500,000 years ago... That was fast...

Who writes this stupid shit?

Maybe "Chinese engineering" brought it back to life by mistake? There ain't NOTHING they can't screw up.

I agree, the 'scientist' who said it was extinct did not know enough to make that declaration, so maybe he wasn't lying but woefully ignorant.

Indeed; sort of like our DEMS in Congress!

I think the confusion is due to sloppy tabloid-grade writing. The article is about the Weishan volcano, which is part of a 193 square mile "volcano field". IOW, Weishan hadn't erupted in 500K years (they have an eyewitness?) but another volcano in the field had erupted in 1776. Later in the article it references another volcano, Paektu Mountain, which is a couple hundred miles to the south, on the border with North Korea. It's a badly written, rather confusing article.

Thank you for the clarification.

What I wanna know, is it a "Kilauea,"  "Mt. St. Helens" or a "Yellowstone" type of volcano?  I'm not inclined to care if it's one of the first two....

express site is often click bait.  For what ever that is worth.

I believe it's a Brit tabloid, which are a little better than the now defunct Weekly Word News (home of "Bat Boy"). As a site, Express is annoyingly slowed by auto-play video and other @#$%.
