The Cassini team announced a possible cyrovolcano on Titan. A key difference between this find and cyrovulcanism on Enceladus is the probable existence of a thousand-meter peak and lobe-shaped flows similar to terrestrial vulcanism. Their video release explains the evidence with 3-d models of the features. More speculative, Guillaume Robuchon speculates that Pluto might have liquid water under an icy surface, assuming it has enough of a rocky core to support heat production through radioactive decay.

Boom! Forget terror attacks, the real reason for an orange alert in NYC has to do with ... rocks. I'll bet you've never heard of Cumbre Vieja. In fact, if the first hit on a google search for something is a PDF, you know it's obscure. (It's a volcano in the Canaries). If it erupts, it'll spell the end for Washington, New York and Boston (and parts of Europe will get a bit wet.) Hoo!

Now, short of hoping it will go away, there's nothing you can do, because it will take 35 million years to dismantle the dangerous bits of rock. Instead, the boffins are talking about evacuating the east coast. Yet more obscure places you wish you could forget menacing the future of the US, hey?

The Three Sisters have developed a bulge in recent years. Earthquake activity has increased significantly in recent days. The level of activity doesn't approach that of Mount St. Helens. Yet.

Yellowstone supervolcano threatens world destruction - That's about it, folks: "Volcanologists have been tracking the movement of magma under the park and have calculated that in parts of Yellowstone the ground has risen over seventy centimetres, almost two and a half feet, since 1923, indicating a massive swelling underneath the park. "The impact of a Yellowstone eruption is terrifying to comprehend." says Professor McGuire. "Magma would be flung 50 kilometres into the atmosphere. Within a thousand kilometres virtually all life would be killed by falling ash" The Yellowstone caldera has been acting up in recent months and we're supposedly overdue for the big one. But don't flee to the East coast: A super tidal wave will get you there. I hear Tierra Del Fuego is nice, except for the Ozone Hole problem. Have a nice weekend. Y'all.

Roden Crater is an extinct volcano in Arizona and doubles as a $7M land art project by James Turrell. I look forward to visiting the site on my next trip to the Southwest.
"If you're not an optimist, forget being an artist," Mr. Turrell said. "I've been lucky. I never felt any entitlement. I'd hoped interest in this work would get going sooner because it wasn't meant to occupy my whole career." The sun was going down and the sky was red and purple. "But that's fine. I have nothing better to do."
