Just imagine , on a clear day from Kanorado state beach you could see the sun setting on The Rocky Island chain. And after that nothing but the deep blue waters of the Pelosi submarine trench.
As of now I bet you got me wrong

Fear-mongering over Yellowstone volcano ramping up again after 1400 tremors.

http://www.express.co.uk/news/science/8 ... arthquakes

Seismic activity around the Yellowstone National Park in Wyoming, US, is not uncommon, but the heaviest swarm in half a decade has people very concerned.

Since June 12, there has been over 1,400 tremors in the region, and experts state that the swarm could go on for another month.

The Yellowstone Caldera supervolcano last erupted 70,000 years ago but a spike in seismic activity around the national park has unsettled nerves.

If the Wyoming volcano were to erupt it would kill an estimated 87,000 people immediately and make two-thirds of the USA immediately uninhabitable. The as the large spew of ash into the atmosphere would block out sunlight and directly affect life beneath it creating a “nuclear winter” and threatening ALL life on earth.

And just when you thought it couldn't get any worse...

The new report fills in a missing link of the system. It describes a large reservoir of hot rock, mostly solid but with some melted rock in the mix, that lies beneath a shallow, already-documented magma chamber. The newly discovered reservoir is 4.5 times larger than the chamber above it. There's enough magma there to fill the Grand Canyon. The reservoir is on top of a long plume of magma that emerges from deep within the Earth's mantle.

I hope you doubters are right for the present. In the long run it is "when" not "if".

Yellowstone may not explode, just flow as the area has in the distant past. This site has real-deal science and lots of short (2 min) videos that explain a lot. Worth your time to visit.

You are missing a zero.
Volcanism at Yellowstone is relatively recent with calderas that were created during large eruptions that took place 2.1 million, 1.3 million, and 630,000 years ago.
One of the irritating thing about the doomers is that they keep saying it blows every 70K years when in fact it was every 700K years. Past performance is also no guarantee of future performance.

No, that's accurate. There have been much smaller eruptions in more recent history. The west thumb was formed 130,000 years ago, tgere was a lava flow around 70,000 years ago, and steam explosions much more recently. It's Caldera forming eruptions that are around every 700,000 years.

I think this can be viewed as the terminology of "blows" (large explosive eruptions forming a caldera) versus plain old "erupts" (as in lava flows)

https://volcanoes.usgs.gov/volcanoes/ye ... ge_54.html

"Three extremely large explosive eruptions have occurred at Yellowstone in the past 2.1 million years with a recurrence interval of about 600,000 to 800,000 years. More frequent eruptions of basalt and rhyolite lava flows have occurred before and after the large caldera-forming events. For example, scientists have identified at least 27 different rhyolite lava flows that erupted after the most recent caldera eruptions, about 640,000 years ago, from vents inside the caldera. The most recent was about 70,000 years ago. Many of these eruptions were separated in time by several tens of thousands of years. Because the evidence of earlier eruptions may have been either buried or destroyed, we do not really know how often the volcano has actually erupted."

My point is that the worst case (huge caldera eruption) that gets touted about is much more rare.

USGS validates that
