Long Valley Supervolcano: World's Most Dangerous Volcano Shows Signs of 'Imminent Eruption'
nature world news ^ | Nov 24, 2021 06:25 AM EST | Rain Jordan

The Science Channel investigated a section of the valley and discovered many clouds of smoke pouring from beneath the ground.

Using InSAR data that has been monitoring the region for the last 20 years, geophysicist Jared Peacock pointed out a worrying aspect of the caldera that might portend problems.

InSAR is a remote sensing method that employs a laser to concentrate a beam of radiation on a target, bouncing back to a sensor on an antenna, providing a comprehensive map of a region.

One of the most concerning sites in InSAR was near Mammoth Lakes, a hamlet in the Sierra Nevada highlands.

A blazing-hot red spot is depicted just beneath the Earth, indicating the presence of magma.

The InSAR data revealed the resurgent dome and checked for signals of problems deep below to see if the Long Valley Caldera was coming back to life.

This activity, however, was not centralized, which is grounds for concern. Instead, it was scarce and dispersed.

The Long Valley Caldera reservoir is predicted to have "significant melt characteristics," with a volume of more than 240 cubic miles (1,000 cubic kilometers).

This melt might be hot enough to burn liquid rock in around 27% of cases.

Long Valley last erupted 100,000 years ago, according to the United States Geological Survey (USGS).

Hi.

“Long Valley last erupted 100,000 years ago, according to the United States Geological Survey (USGS).”

Who told the USGS that eruption happened?

Someone has a Delorean...

5.56mm

Why is it creepy? Serious question. I have never been there.

“Spray it with Flourine.”

Do you think the Long Valley volcano plans on doing that?

Right - a bit out of it here - for everyone's edification, the USGs says :
The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning that at one point in time it erupted more than 1,000 cubic kilometers (240 cubic miles) of material.

In the early 2000s, the term “supereruption” began being used as a catchy way to describe VEI 8 eruptions. Explosive events of this size erupt so much magma that a circular-shaped collapse feature, called a caldera, forms above the evacuated magma storage region.

The largest (super) eruption at Yellowstone (2.1 million years ago) had a volume of 2,450 cubic kilometers. Like many other caldera-forming volcanoes, most of Yellowstone’s many eruptions have been smaller than VEI 8 supereruptions, so it is confusing to categorize Yellowstone as a “supervolcano.”

Other caldera-forming volcanoes that have produced exceedingly large pyroclastic eruptions in the past 2 million years include Long Valley in eastern California, Valles Caldera in New Mexico, Toba in Indonesia, and Taupo in New Zealand. Taupo erupted 22,600 years ago and is the most recent supereruption on Earth (with a volume of about 1,130 cubic kilometers).

Additional volcanoes capable of producing supereruptions include the large caldera volcanoes of Japan, Indonesia, and South America.

Note : I think there is also a Yellowstone like super volcano in Eastern Siberia, Russia

Krakatoa wasn’t a super volcano? I know it was heard damn near around the world but that is seriously scary that that eruption isn’t a considered all that big. Holy crap.

From the article you posted...

“A robust geothermal system inside the caldera fuels the Casa Diablo power plant, which generates enough power for 40,000 homes.”

I don’t Spanish, but doesn’t CASA DIABLO translate to the “house of Satan”?

"Krakatoa wasn’t a super volcano?"

Krakatoa is not classed as a super volcano; I believe it was a VEI 6. Tambora which erupted in 1815 and apparently triggered "the year without summer" in 1816 was larger, I believe a VEI 7. I also believe that Tambora is the largest eruption in historic times. The Tambora eruption was heard as far away as Singapore and was heard in Batavia (now Jakarta).

One of the features of the Victorian parlor was the recording barometer and these recorded 7 pulses of the shock wave from the eruption in 1883 that traveled around the world.

Nope. The pressure is from miles underground and the top level magma is just a tiny fraction of that pressure and only represents an indication of what is below.

A big one would reverse “climate change” very rapidly, and likely cause a new ice age.

Wouldn’t Pelosi actually be safer in San Francisco, being upwind of the volcano? (at least until the ash cloud circles the globe). It’s depressing to think that there might actually be an advantage to living in poop town, but if given the choice I think I’d rather deal with a choking volcanic ash cloud than living there.

What about Woolly and Columbia Mammoths, Dire Wolves, Smilodons, Short Faced Cave Bears, Aurochs and other tasty animals, will they come back also?

Krakatoa was noted for being explosive, not necessarily how much magma it had to expel as lava and ash.

Hmmm...

This means, at a minimum, that everything as far away as, for example:

will be buried under several feet of ash...

That could affect Soros' plans for stealing the 2022 & 3034 elections...

Also, plans will have to be made & implemented to move about 25,000,000 illegal migrant invader vermin from those states to the eastern seaboard...
Each of their $450,000 reparation pmts will be sorely needed to boost the post-apocalyptic economies...

I'm not an engineer. But lets think of a pressure cooker. If heat keeps being applied, it will eventually expode. But it has a steam vent that prevents it from happening.

Why not the same concept to drill holes that vent the pressure?
