First things first: The proprietor of this blog extends his own thoughts and prayers to the very many that are going out to our friends down Chile way today, in the aftermath of the 8.8 earthquake that rocked that country in the wee hours this morning.

And by the way, it’s a great testament to that country about how on the ball the folks are about this. I’ve heard only great things about Chile over the years and the speed and diligence that they have exerted in dealing with this disaster, makes me compelled to tip my hat to ’em.

If you haven’t already today, it would – not to put too fine a point on it – be extremely recommended that you tune in right now to CNN or Fox News or whatever, and check out the live feed coming from Hawaii, which looks to have dodged the proverbial ...

Not really trees, but an optical illusion captured by NASA’s HiRISE camera in orbit around the red planet. What appears to be a scattering of pine trees is actually several trails of debris near Mars’s north pole, left behind as the ice cap goes on its seasonal retreat.

Markus Haering appeared in court in Basel, Switzerland today. The charge leveled against him: that his company’s activities caused earthquakes, one of which measured 3.4 Richter magnitude. Haering’s firm is researching geothermal-generated electricity. Well, according to court documents his company’s deep-drilling in 2006 triggered the quakes. There were no injuries but $9 million in damages were reported. If the judge finds him guilty of intentionally damaging property, Haering faces five years jail for making the earthquakes happen…

…which is gonna be a heckuva retort when he gets asked “So what are you in for buddy?”

(Seriously though, sounds like it’s gonna be an easy charge to beat. Lex Luthor might have been put behind bars for doing something like this but not Markus Haering. Dude doesn’t even have a nuclear weapon, fer pete’s sake…)...

It’s long been speculated that the Great Rift Valley in Africa will someday split entirely and create a new ocean, but now we have hard scientific evidence that it’s not just theoretical… it is happening now! In 2005 a massive, 35-mile long new rift opened up in Ethiopia (part of it pictured at top). According to a new study published in Geophysical Research Letters, it’s been confirmed that the same process that happens on the ocean floors of the Atlantic and elsewhere (think Mid-Atlantic Ridge) is taking place in eastern Africa. Someday that rift that you see in the photo will split apart completely and become a whole new ocean!

So consider buying up beachfront property now. It’ll be worth a lot of money… in a few million years or so....

The next time you hear someone speak of a thing as being “old as dirt”, now you’ll have some context for it…

Deep in the Negev Desert of Israel, scientists have discovered what is being called the oldest patch of exposed ground in the world. It’s been dated at around 1.8 million years old.

Pretty humbling, aye? To know that there are still places in this world that defy the savagery of both nature and man. It’s much like whenever I go out on the Blue Ridge Parkway in the western part of North Carolina: seeing all those mountains, knowing that they were here long before us, and will still be there long after we are gone.

And who knows? This might literally be ground that Abraham, or Joseph, or Moses once walked upon. Perhaps even Jesus Himself, who we are told went out into the desert for forty ...

Just south of the equator and nearly two miles below the surface of the Atlantic Ocean, researchers have discovered the hottest liquid water ever found on Earth, in a state that has never before been observed in the natural world. Hydrothermal vents are discharging water in a “supercritical” state (I’m thinking it’s analogous to plasma as a super-heated gas) that has been recorded to get as hot as 464 degrees Celsius. For us American folks, that’s a whopping 867 degrees Fahrenheit for liquid water! The conditions are so adverse surrounding the vents that computer modeling is the only way to study them, since regular equipment would melt from the heat.

Interesting stuff. Great fodder for discussion for any science and physics teachers out there who want to get their students thinking about how things like temperature and pressure affect water’s properties....

That’s one helluva carbon footprint …

Near the small town of Darvaz in Uzbekistan is a place that the locals call “The Door to Hell”. Thirty-five years ago some geologists were drilling for natural gas there and hit upon a cavern. Poisonous gas was detected down in the hole, so the excavators ignited it in the hopes that it would “burn off” and clear out the air so that they could explore further.

It’s been burning ever since, non-stop, for more than three decades.

Mash down here for more photos and one scary video clip of “The Door to Hell”.

EDIT 2:28 pm 03/30/2008: Someone noted in the comments that Darvaz is actually located in Turkmenistan, not Uzbekistan. So I stand corrected. But in my own defense, I just took the original website at its word that this was Uzbekistan 🙂...

Researchers from the University of Bologna in Italy have identified what might be a crater from the Tunguska blast in 1908. The alleged crater is a bowl-shaped lake that seems to be a recent geological feature. There’s evidence of buried rock beneath the lake that could have come from an asteroid or cometary remnant. And a few other details seem to jibe well, too. Very cool stuff if this bears out: the Tunguska event is perhaps the most frustrating natural disaster in modern history, since it was two decades before the Russians were able to send a team out to study the site. We still don’t know what happened that day, ‘cept it was detected as far away as England and it knocked horses plum off their legs for hundreds of miles around....
