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.

Bed-making at our house tends to run into Jake.
I like the bed-lumps during bed making!
Now I have to go comb my head out. I desperately need a hair cut. It’s looking really scraggly, for some reason, and the natural wave isn’t showing up unless I force it. :o[
The cats have been in and out and in and out. Now the byos are arriving, with moans and groans.
Happy Marine Corps birthday!
Yes, it is the Marine Corps’ birthday! How is Elen, USMC?
I need to go over and check my mail, and then I’ll head out for Walmart. NOT looking forward to that at all! My hands are cold so I don’t think my gloves will do much good.
Later.
Good morning. Happy Twosday!
Kitteh doesn’t seem to understand this cheating death thing.
Elen, USMC, was fine the last we heard. Good luck at Walmart!
Kitteh has stared down Death and didn’t lose a whisker.
Happy Trash Day! It’s “Bulk Pickup Day.” I’m going to put my hiking boots on and go scavenging.
Happy Trash day.
39 and sunny here. The folks at The Weather Channel think it will rise to 69 by some point with a little chance of rain.
The trip to Walmart was freezing cold. Literally. And there was ice on the windshield. On top of the dust from Thursday’s dust-blowing incidents by Dismally Inept Lawn Service. I should probably change the name to something like, The One Man, Three Machine Lawn Service, or something, since he works alone, now.
After three days of dark and gloom and two days of rain with dark and gloom, today promises to be somewhat sunny for a while.
The news from CO is that both parties are on the mend, and that’s a relief. All these months, FD has been disputing my claims that Covid is a strain of flu and should be treated like any other with a few minor tweaks. Her doctor confirmed Saturday to treat it as they would the flu. She has changed her entire mindset almost overnight, flying in the face of “what the CDC says, Mom!” ;o]
So the rest of the day is downhill, I think. I hope.
I didn’t find anything I felt like bringing home.
I’m glad your daughter and the guy are doing better.
I brought home what I had to and no more. Sometimes, there are nicely stocked shelves and others, it’s like a grab bag.
FD and The Guy just put in for emergency FMLA so at least they get paid for their time off. She hasn’t had a day off since last Thanksgiving so this is a good time for her to rest up. He was laid off for a while, and his first time back was when I was visiting them.
She sounds much better, emotionally, today. Relief! ;o]
That’s good. I’m going to stop in at Walmart when I drop Pat off at work. I’m out of a few things.
I just all of a sudden ran out of gas.
I had to print up a map of where I’m supposed to go tomorrow, as it’s been so long since I’ve been to the ophthalmologist’s. I was dreading that long, uphill climb to Telegraph Road, and then I readjusted my thinking. Another excellent opportunity to exercise my uniquely Utah Driving Skills! :o])
We were supposed to lose power sometime between 8:30 and 2:30 so they could power up the new EV charging stations they put in our parking lot. We lost power AT 8:30 and it came back on at 4:25.
This isn’t rocket science. They could be on time. But they never are.
Let’s not even TALK about the times we went out today to see people just sitting by the power junction box.

Back from the stable. Horses were ridden.
Sorry about the extra post. I have the hiccups.
It’s okay.
As we say around here, “If it ain’t one darn thing, it’s two darn things!”
Well, some folks get as much for sitting around as they do for actually doing work, so... I like to think they’re practicing for the unemployment lines. ;o]
