Long Valley Supervolcano: World's Most Dangerous Volcano Shows Signs of 'Imminent Eruption'

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).

It’s the lake. Prehistoric.

Geological clocks tick a bit slower than ours.

In case anyone else was wondering.

“Mammoth Lakes is a town in Mono County, California, the county’s only incorporated community. It is located immediately to the east of Mammoth Mountain, at an elevation of 7,880 feet. As of the 2020 United States Census, the population was 7,191, reflecting a 12.7% decrease from the 2010 Census.Wikipedia”

Paging Elon Musk, we’d like that backup of humanity in place ASAP…

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

So lets just ignore that sitting in a drilling rig over a volcano aspect of it.

There is _INTENSE_ pressure from below. Opening a fissure would probably result in exactly the opposite of what you're trying to do here. Once the magma started moving, it would erode the hole larger and larger until it all comes out like popping a zit. I suspect that it would happen in fractions of a second.

Be thankful that there are mountains of rock sitting on top of that magma dome.

The continental United States has approximately 3.8 million square miles.

240 cubic miles / 3.8 million sq. miles = 4 inches of ash.

So at least 1 foot in the western 1/3 of the US if it all just went straight up and straight down.

The first cleansing of the Earth was with water and the next will be with fire.

All things considered and knowing of His past examples, if God was going to pick a place today to start burning His trash, do you think this one would work?

With a mile thick ice sheet, there won’t be much to smilodon about.

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

Until recently discovered it was believed elemental Fluorine existed nowhere in nature. Chemists actually died and many were injured trying to isolate it.

I found an old book about Krakatoa. Had all sorts of historical and scientific stuff in it. Amazing watercolors based on descriptions from sailors, etc.

That’s what I was thinking too - it didn’t get a graph on that page!? The tsunami was the neatest thing I thought. It was huge. The book had harbor charts from around the world showing the change in water depth due to the eruption and tsunami. In England even!

Unfortunately, it will not be distributing uniformly across the country...
Gravity sees to that...

That was the point I was trying to make. It will be based on direction/side of the caldera it blows from and the winds.

I lived in Tri Cities in eastern Washington when St. Helens blew. We barely got anything as it went northwesterly.

The author’s name is Rain.

Just throwing that out there.
