Scientists: Yellowstone Supervolcano May Be Ready to Erupt

, Monday, 16 Dec 2013 09:26 PM

Quote:
The hot molten rock beneath Yellowstone National Park is 2 ½ times larger than previously estimated, meaning the park's supervolcano has the potential to erupt with a force about 2,000 times the size of Mount St. Helens, according to a new study.

By measuring seismic waves from earthquakes, scientists were able to map the magma chamber underneath the Yellowstone caldera as 55 miles long, lead author Jamie Farrell of the University of Utah said Monday.

The chamber is 18 miles wide and runs at depths from 3 to 9 miles below the earth, he added.

With all our technological advances, we're still in the hands of Ma Nature. She sends us massive cyclones, earthquakes, volcanic eruptions, and our scientists still aren't sure why – or even have the faintest idea of who to stop it.

When Will Earth Lose Its Oceans?


Quote:
Dec. 16, 2013 — The natural increase in solar luminosity-a very slow process unrelated to current climate warming-will cause the Earth's temperatures to rise over the next few hundred million years. This will result in the complete evaporation of the oceans. Devised by a team from the Laboratoire de Météorologie Dynamique[1] (CNRS / UPMC / ENS / École polytechnique), the first three-dimensional climate model able to simulate the phenomenon predicts that liquid water will disappear on Earth in approximately one billion years, extending previous estimates by several hundred million years. Published on December 12, 2013 in the journal Nature, the work not only improves our understanding of the evolution of our planet but also makes it possible to determine the necessary conditions for the presence of liquid water on other Earth-like planets.

Oh my goodness? Where can we run to? How can scientists stop this? Another regulation on the use or coal or petroleum? Read more of this dire news @ When will Earth lose its oceans?

With how technology is advancing specifically information technology this will not be the case much longer. In fact we will be living in a completely different world by 2030-2045.

If we survive that long!

The type of tech required for stopping a volcano or other natural events of that magnitude is hundreds if not thousands of years into the future.


Edit: just for some perspective, this was Mt. St. Helen's:

The total energy output, on May 18, was equivalent to 400 million tons of TNT - approximately 20,000 Hiroshima-size atomic bombs.
This is Mt. St. Helen's compared to Yellowstone.

That is liner thinking but information technology advances exponentially so we will see that kind of advancement in the next 50-100 years.

The likelihood of a super volcano erupting in the next 1,000 years is very low so we are safe. Well before then we will be advanced enough to deal with anything mother nature can do.

This is from the National Park Service:

Q: How imminent is an eruption of the Yellowstone Volcano?

A: There is no evidence that a catastrophic eruption at Yellowstone National Park (YNP) is imminent. Current geologic activity at Yellowstone has remained relatively constant since earth scientists first started monitoring some 30 years ago. Though another caldera-forming eruption is theoretically possible, it is very unlikely to occur in the next thousand or even 10,000 years.

The most likely activity would be lava flows such as those that occurred after the last major eruption. Such a lava flow would ooze slowly over months and years, allowing plenty of time for park managers to evaluate the situation and protect people. No scientific evidence indicates such a lava flow will occur soon.

Curious how the Hawaiian islands would fit in that chart.

Especially as they are basically the parts of active volcanoes above the ocean's surface and are growing every day due to active lava flows.

It is true. Over the course of the next ~500 million years the sun's luminosity will increase by ~10% as it ages, which will be sufficient to increase the temperatures beyond what the oceans, or complex life, can withstand.

Complex life first appeared approximately 540 million years ago during the Cambrian Period. Now it looks as if we have reached the half-way point for complex life. In another 500 million years or so everything (except possibly thermophile bacteria) will be extinct.
