There are around 20 known super-volcanoes on Earth, with major eruptions occurring on average once every 100,000 years.
One of the greatest threats an eruption may pose is thought to be starvation, with a prolonged volcanic winter potentially prohibiting civilization from having enough food for the current population. In 2012, the United Nations estimated that food reserves worldwide would last 74 days.
“I was a member of the Nasa Advisory Council on Planetary Defense which studied ways for Nasa to defend the planet from asteroids and comets,” explains Brian Wilcox of Nasa’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology. “I came to the conclusion during that study that the supervolcano threat is substantially greater than the asteroid or comet threat.”
When Nasa scientists came to consider the problem, they found that the most logical solution could simply be to cool a super volcano down.
A volcano the size of Yellowstone is essentially a gigantic heat generator, equivalent to six industrial power plants. Yellowstone currently leaks about 60-70% of the heat coming up from below into the atmosphere, via water which seeps into the magma chamber through cracks. The remainder builds up inside the magma, enabling it to dissolve more and more volatile gases and surrounding rocks. Once this heat reaches a certain threshold, then an explosive eruption is inevitable.
Nasa have conceived a very different plan. They believe the most viable solution could be to drill up to 10km down into the super volcano, and pump down water at high pressure. The circulating water would return at a temperature of around 350C (662F), thus slowly day by day extracting heat from the volcano. And while such a project would come at an estimated cost of around $3.46B, it comes with an enticing catch which could convince politicians to make the investment.
But drilling into a super volcano does not come without certain risks. Namely triggering the eruption you’re intending to prevent.
“The most important thing with this is to do no harm,” Wilcox says. “If you drill into the top of the magma chamber and try and cool it from there, this would be very risky. This could make the cap over the magma chamber more brittle and prone to fracture. And you might trigger the release of harmful volatile gases in the magma at the top of the chamber which would otherwise not be released.”
Instead, the idea is to drill in from the super volcano from the lower sides, starting outside the boundaries of Yellowstone National Park, and extracting the heat from the underside of the magma chamber. “This way you’re preventing the heat coming up from below from ever reaching the top of the chamber which is where the real threat arises,” Wilcox says.
I am sure NASA would hire someone to do test drilling for their grand plans. Perhaps a smaller volcano first, one that would draw less attention.
Which leads me to two recent articles I found.
Montana environmental regulators have set a reclamation bond at just over $154,000 for gold exploration on private property north of Yellowstone National Park.
The Bozeman Daily Chronicle reports Lucky Minerals Inc. argues the bond is too high while mine opponents feel it is too small.
The bond is set at what the state Department of Environmental Quality estimates it would cost to reclaim the area if Lucky Minerals failed to do the work.
Late last month, the Montana DEQ approved Lucky Minerals’ plans to drill 46 exploratory holes near Emigrant Peak. The DEQ calculated the bond on having to refill 12 holes because it plans to inspect the site periodically.
Lucky Minerals vice president Shaun Dykes says the company plans to have only two drill holes open at a time. Drilling could begin this fall.
Exploratory mining permit for near Mount St. Helens advances
Exploratory mining near Mount St. Helens is now one step closer to happening.
The U.S. Forest Service found no reason to object to an application by Ascot Resources Ltd. of Vancouver, B.C., to prospect or explore for minerals in the Gifford Pinchot National Forest about 12 miles northeast of the Mount St. Helens crater.
The agency issued a draft decision to consent to the Bureau of Land Management approving Ascot’s plans.
Starting Thursday, the public will have 45 days to object to the Forest Service’s decision.
But, according to the decision notice, “objections will be accepted from only those who’ve previously submitted timely, specific written comments regarding the proposed project unless based on new information arising after designated comment opportunities.”
In the draft decision, Cowlitz Valley District Ranger Gar Abbas acknowledged “a great deal of concern” that approving the exploratory drilling would pave the way to a new mine, but he emphasized several times throughout the document that wasn’t the case.
“This consent decision is not for mining,” he wrote. “It is specifically and only for authorization of up to 63 roadside exploration holes measuring 2-3 inches in diameter, subject to specified conditions and protective design features.”
Abbas’ assertions are unlikely to quell the discontent of those who’ve watched and opposed the project since at least 2011.
“I think this decision is ridiculous,” said Matt Little, executive director of the Cascade Forest Conservancy, a Portland-based conservation group. “I think it’s mind-boggling how the agency could totally ignore tens of thousands of citizens who’ve asked them to protect the Green River Valley and instead cater to the Canadian mining company.”
Ascot wants to search for copper, gold and molybdenum on a mining claim in the upper Green River Valley at Goat Mountain, where its subsurface rights are evenly split with the federal government.
While the BLM has the authority to grant Ascot’s permits, the Forest Service must consent to the project since it would occur in the national forest.
In January 2016, the agencies released a modified environmental assessment for the exploratory drilling permit application to address a federal court’s 2014 decision that invalidated Ascot’s drilling permits and held that the two agencies violated the National Environmental Policy Act. The decision was the result of a lawsuit filed by the Cascade Forest Conservancy, formerly known as the Gifford Pinchot Task Force, in which they sued to halt Ascot’s drilling plans.
The Cascade Forest Conservancy claims more than 20 recreation and conservation groups oppose the project and any potential mine that could ultimately result. And Little said he’s urging opponents to take the time to formally object to the Forest Service’s decision.
“After that it gets into a potential lawsuit,” he said.
In a stakeholder’s letter, Abbas said his decision “best addresses the balance between resource use and resource protection with an emphasis on the protection of riparian reserves.”
But in response to the decision, Steve Jones, director of Clark-Skamania Flyfishers, said the prospecting is a threat to wild steelhead in the nearby Green River and the rest of the Toutle and Cowlitz River system.
“This river drainage needs to be conserved, not exploited,” he said.
The Green River is a state-designated gene bank for wild winter steelhead, meaning hatchery fish are verboten within. It’s also a candidate for a federal Wild and Scenic River designation. Some of the land in question was purchased by the U.S. Forest Service in the 1980s with money from the Land and Water Conservation Fund, which is meant to serve the interests of recreation and conservation.
The Washington, D.C.-based conservation organization American Rivers has twice declared the Green River, with its headwaters running close to the proposed mining area, as one of the most endangered rivers in the nation.
In March of last year, U.S. Sen. Maria Cantwell, D-Wash., wrote in opposition to the project in a letter to then-Forest Service Chief Tom Tidwell, arguing that mining activity would likely interfere with recreation and conservation on the land, which were the reasons behind the purchase.
Now I am not saying that for a certain they two mining operations are related to the what many people are calling a insane plane to cool down a volcano, but these was the types of things on should be looking for if NASA want’s to keep their project hush-hush.
After all according to YVO the NASA information was a leak that was not suppose to get out.
