catching up

I want to use this blog well, but the reality is that I have a badly flaring chronic illness, an active infant approaching toddlerhood, have spent the autumn moving and unpacking, and just can't keep up with thoughtful, well-written posts. Thus, I've decided that instead of putting things aside for sharing "when I can write about them better," I'm just going to give up and share.

So here, at 6 am today, while my husband and I were hanging out with a very happy, awake infant, we were also laughing at this video. Mind you, it started with serious ooohs and aaahs at the wonder and science of melting brine turning into some sort of weird frozen stalactites projecting from the ice sheets of the Antarctic into the cold water below, then it just became a riot of giggles at the timelapse shots of starfish trying to escape the "Day after Tomorrow" scenario. It's worth a watch.

the truest sense of awesome

Today's tornado crosses the Connecticut River in Springfield, Massachusetts.



The tornado caused moderate damage and no deaths, nothing like the spate that's plagued the midwest, but still, nothing to scoff at.

The clearest version of this video - long, no titles - I've encountered is in Facebook, but that's not embeddable here. If you'd like to look, check it out here: http://www.facebook.com/video/video.php?v=2063834605138

correction: four deaths

look at what liquefaction can do

Isn't that amazing? Look at the water gooshing up, and the swaying dirt. Holy cow. I'd rather be in open space, even liquefying open space, in a big quake, than in the middle of a city, or *sigh* within the first few blocks of a Japanese coastal town, but still, that just makes the bottoms of my feet crawl to watch.

In the San Francisco bay area, we keep talking about building on marshes. Look at that ground! You are going to have a hard time convincing me to live on that.

I have a big Japanquake post in notepad on my desktop, just waiting for some more anchor tags and rounding out with citations, and I will finish it today. This doesn't really fit in there, though, so I'm sticking it here now. The baby is due this weekend (but might come a little late) so I'm a tad bit distracted.

The frontier is everywhere.

I want to come back in some-odd thousands of years and look back, just to see where we've come, and find out what this chunk of time means in the grand scheme of things.

time-lapse solstice eclipse

My writing fu just seems stuck lately, what with planning for impending baby, some health issues, and .... well, I have no other excuses. But here's neat time-lapse video of last night's eclipse!

I have a bookmark file full of things to write about, and rather than go on hiatus, I think I'll toss them up as I'm able. I apologize.

first rickroll in space

I love video of uncontrolled helium balloon descents.

Christchurch earthquake pictures

(Look at that vertical displacement!)
(edit: A couple of friends have since reminded me that "displacement" is a specific geologic term with regard to quakes. This offset might not be ground displacement as much as separation due to liquefaction or localized sinking.)

After I looked at these, I reminded my husband that we haven't replaced the attachment hardware for our bookshelves, so we'll do that this weekend.

We also need to re-inventory our quake kit and find out what we need to replace. My favorite list of supplies is sfgate.com.

Folks from Christchurch respond to last night's big quake:



The panicky woman couldn't have known then (and many folks don't know, in general) that the quake wasn't really big enough for a tsunami, especially given as it was centered under land. They're usually from bigger quakes centered under water, with specific seismological conditions. But when the ground has bounced you out of bed in the wee hours of a winter's morning, that's probably not your first thought.

there's a lot going on down there

It's not exactly as good as being on the ISS, but it's still amazing:



Timelapse of Earth from low orbit. The lights below, the aurorae, just lovely. I want to lie in the cupola and stare.

Cotopaxi volcano

What a lovely Milky Way, just rotating right over the top of it!

way slow lightning

Watch the timestamp move. The whole video is slowed down to 1/300 speed.

It's interesting to watch the big bolts form, and disappear, but I am in love with all the tiny baby bolts.

2009's Atlantic/Caribbean tropical storms, all at once

NASA and NOAA have put together a four-minute time-lapse animation of the 2009 hurricane season:



I find myself trying to peer beyond the bottom right corner, to see what's going on between the Caribbean and Africa.

At least as interesting as watching the tropical depressions form and move, though, are the way clouds form over Central America. I'd like to watch a time lapse of Panamanian skies from the ground below, based on this.

death by clam?

That's a horrible and fascinating phrase.

I have no idea when this short National Geographic web exclusive on Hulu.com will last, but it's here now:





I'm a big fan of molluscs, I find them endlessly fascinating. (I also find them occasionally tasty. I'm about 99% vegetarian, but small bivalves rock my culinary world.)

I didn't really know much about giant clams. I guess I assumed that they lived in the deep sea (they don't), and that they were a lot like large versions of normal clam species. But they have nifty skin not unlike a squid's (less shiftingly chromatophoric*), and I had no idea about their relationship with algae!

Also, let it be said that the diver at the end of this clip is a doofus. Don't go messing with sea animals or coral reefs, Doofus Diver.

*It's amazing what blogger labels as incorrectly spelled. What, that's not a word?

The Raging Grannies have an opinion

Okay okay one more! But I promise content just as soon as I finish dinner dishes.

earth-shattering kabooms!

Brian Romans, from Clastic Detritus, pointed out on twitter that in recent Icelandic volcano footage, one can see amazing shock waves propagating through the ash cloud after explosions.

Wow! The air vibrates beautifully. Have a look. It happens several times in this video.



Wikipedia says, incidentally, that

The name Eyjafjallajökull is made up of the words eyja (genitive plural of ey, meaning eyot or island), fjalla (genitive plural of fjall, whose nominative plural is fjöll, meaning fells or mountains) and jökull (meaning glacier, cognate with the -icle in icicle). A literal translation would thus be the "island-fells glacier" or the "island-mountains glacier". The name Eyjafjöll describes the southern side of the volcanic massif together with the small mountains which form the foot of the volcano. The village and museum of Skógar are also part of the region undir Eyjafjöllum (meaning "under the Eyjafjalls").

So it's Eyjafjöll that's erupting? It's complicated.

Goodness gracious

Dan Satterfield linked on his facebook page this news video of the meteor that lit up the midwest last night:



The Christian Science Monitor (which has a great photo of the fireball) says

A large flash of light at about 10 p.m. Wednesday night – described as a fireball in the sky by eyewitnesses from Wisconsin to Missouri – was most likely a meteor from the ongoing Gamma Virginids meteor shower.
It is unknown whether the meteor in Wisconsin, which was seen flying eastward at an altitude of 6,000 to 12,000 feet, hit the ground or burned up in the atmosphere.

There's more at that link.

Updates on the European ash situation

From AlJazeera, an information-filled and relatively accurate story (text story at that link) about the effects of Eyjafjallajokull's eruption:




The BBC has more too, on their site, including this important tidbit: "The UK's air traffic control service (Nats) said no flights would be allowed in UK airspace until at least 0700 BST on Friday amid fears of engine damage."

• Icelandic volcanic ash alert grounds UK flights
• Photo of ashcloud from the air, changes once an hour
• Iceland's volcanic ash halts flights in northern Europe
• Why a cloud of ash has grounded flights
• The National Post has a map showing closed airports

Today's ashcloud from space:



Because the clouds make it hard to see a visible-light photo, the Norwegian meteorological office released this one


(I'm a tad embarrassed to ask: What wavelength is this? not infrared.)

The glow from the ground:

Eyjafjallajokull volcano still erupts dramatically

My initial reaction was actually (in text, to a friend), "omg omg omg omfg geology."



Right now, several airports in Europe (specifically Norway and the UK) are closed because of ash.

Boston.com's "The Big Picture," one of the best photoblogs on the web, collected pictures of the volcano and its effects today. Some aren't the usual fare, some are especially dramatic, but I think one that most caught my eye was #11 - people in snow gear, standing on dirty snow with ski poles stuck in it, watching flowing lava from a few feet away.


(And for the sake of fun: KCBS said, on twitter: "Why we're just calling it 'a volcano in Iceland'. Try saying this: Mt. Eyjafjallajökull (ay-yah-FYAH'-plah-yer-kuh-duhl)" Wikipedia provides the IPA [ˈɛɪjaˌfjatlaˌjœkʏtl̥]) and an audio clip to unconfuse things.)

Addendum: My friend Ailbhe, in the thick of things, clarifies the current airport closure and flight diversion issues -- "UK, Ireland, Norway, Sweden, Denmark, north Finland, Belgium, north France, the Netherlands in parts" -- and provides a link to a good reason: Volcanic ash destroys airplane engines catastrophically.

Fascinating Northridge quake coverage

I did spot one major technical/factual mistake, though.



(Have I posted this before, years ago? I should look. But it's a cold, rainy morning, and the dog is asleep on me, and that sounds like a lot of work for today.)

The shaping of the Great Lakes, in an hour

The History Channel's new series, "How the Earth was Made," is mostly just scientific enough for me today, as I'm fighting a low fever, and wanted to stare at something educational without spraining too many neurons. Today I sat down with Hulu and watched an episode about the creation of the Great Lakes.



I knew some of it, such as the glacial history, but hadn't known about the igneous origins of the floor beneath Superior and Ontario. The series is presented in steps, giving evidence for theories (with a bit of the History Channel's typical "but that's not all" and "there's more they didn't know," and "but still, mystery remained" drama), then before each ad, recapping the bits. I appreciated those, it helped me knit the story in stages before going on to the next chapter in the story.

As it turns out, I had no idea how fast Niagara Falls was receding. Do you know? What would you guess? Watch the show and see. I was a tad stunned.

(If the Hulu.com video expires, you can find the video for sale at the History Channel website, with a few clips and full episodes still available.)

Imagine being terrified of tiny tremors, for good reason

The recent 5.6 earthquake in Cuba brought down a house in Haiti, and killed two people (at least, so far).



In a country as shaky with aftershocks as Haiti has been, and recent torrential rains making life miserable for people who live under tarps, and still live in gullies (as they have for a long time), imagine if every time the earth shook just a little, you feared for your life. The people under tarps are wetter, but perhaps safer.
