A team of geologists at the University of Houston College of Natural Sciences and Mathematics believes they have found the lost plate in northern Canada by using existing mantle tomography images—similar to a CT scan of the earth's interior. The findings, published in Geological Society of America Bulletin, could help geologists better predict volcanic hazards as well as mineral and hydrocarbon deposits.
"Volcanoes form at plate boundaries, and the more plates you have, the more volcanoes you have," said Jonny Wu, assistant professor of geology in the Department of Earth and Atmospheric Sciences. "Volcanoes also affect climate change. So, when you are trying to model the earth and understand how climate has changed since time, you really want to know how many volcanoes there have been on earth."
Wu and Spencer Fuston, a third-year geology doctoral student, applied a technique developed by the UH Center for Tectonics and Tomography called slab unfolding to reconstruct what tectonic plates in the Pacific Ocean looked like during the early Cenozoic Era. The rigid outermost shell of Earth, or lithosphere, is broken into tectonic plates and geologists have always known there were two plates in the Pacific Ocean at that time called Kula and Farallon. But there has been discussion about a potential third plate, Resurrection, having formed a special type of volcanic belt along Alaska and Washington State.
Using 3-D mapping technology, Fuston applied the slab unfolding technique to the mantle tomography images to pull out the subducted plates before unfolding and stretching them to their original shapes.

W00t!
There was a vid clip on FB this morning (WAY early) about a decoy mallard in the grass, and a falcon trying to get some action out of it. It would grab the decoy by the head and try to pick it up, but couldn’t get a grip. Literally. I watched that clip for the full two minutes, laughing the entire time. So I would imagine that a predator would miss one of your cats.
I heard some warblers in the bare trees out by the street so maybe spring isn’t too far away. And if not, then I might be able feel more like packing.
Last night, I thought I’d feel well enough to do some today, but then I was awake for three hours in the middle of my night, so I feel like dirty laundry. Or thirty miles of bad road.
Nature is a hoot.
And now we’re back to the owls.
Oh, you slay me, ArGee! :o])
Bill the Cardinal and the James the Mourning Doves think it will be spring soon.
As long as it isn’t that I LITERALLY, LITERALLY slay you.
I don’t know what was singing to me this morning, but the song was very pretty so I think it must have been a lark. Or maybe several. No buds on the trees, yet, but if the birds are here, it won’t be long.
I still don’t know what kinds of birds are in the area, besides the various hummingbirds on their ways to somewhere else.
Nah, I don’t think you’d do that, even if you had a chance. You have no reason... I don’t think. ;o]
Afternoon. My computer has been having a nervous breakdown today. Super annoying. Maybe it will recover overnight while it’s resting.
Your computer and I both need to recover from a nervous breakdown.
See ya tomorry, then! ;o]
Kitteh gonna pounce!
Good morning.
The doorbell rang around 1930 and I opened it to find some Young Women from the ward, who had stuck valentine hearts to my storm door. When I opened the door, all groggy and grumpy, I was met with five happy voices wishing me “Happy Valentine’s Day!” while handing me a heart-shaped cookie!
I couldn’t figure out why they were so early, and then I realized that Sunday is Valentine’s Day and they won’t do that on a Sunday.
Anyway, I found out this morning that I’ve lost enough weight to get into one of my favorite outfits!! Linen shirt and crocheted skirt. THAT makes my day!
Good morning. That’s exciting!
I got up, prodded by Jake, to find a cat spew on the kitchen floor. I saw it just before I stepped in it.
The visit last night? The clothes that fit? Or all of the above are exciting?
No matter! And yes, I agree! ;o]
I don’t think there is any worse thing than to step in cold cat spew. *shudder* I’m glad you missed it.
PS: I stepped out to take the hearts off the door and there was a box on the stoop.
One of the hearts (three different sizes, types and colors) had “Heart attack” printed on it in red ink!
The box was the rest of the order from iHerb, the first box of which came after I was in bed yesterday afternoon. GAH! No knock, no doorbell.
Good morning, all. Happy Friday Eve!
All is calm here except we got our new lease for the upcoming year and it includes a generous 15.5% increase over our current rent. So it looks like we’ll be moving in April. Fun, fun, fun.
There is. I shan't elaborate.
Happy Friday Eve!
That’s just totally wrong about the rent increase. I hope the landlord likes all the vacancies he’s providing. Of course, if this is something he does every year, and plans on it to bring in new people who don’t mind paying the increased cost, (not an increase to them until the lease is up) he may find himself increasing himself right out of viable tenants. Greed is a terrible thing to see in action, in real time.
Yes, and I probably thought of it and took the lesser of two evils.
