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.

Yes, and now it’s time for my to get myself into the mode of getting into the mode, and I really would rather stay home. The cold has made my back into a thing that is better left on the garbage heap. I move and I get chilled, just as if I had a fever. I know what it is — and I’d be smart to stay home.
Unnngh.
I’m going to take a shower before something happens to the hot water!
Well, I forced myself to get dressed, but it was into an outfit I really hadn’t planned on wearing, but it’s too late to change again. The only thing that I didn’t have to change was the jewelry — coral. One of my favorites.
Anyway, I’ll see you when I get back.
I hope you had some hot water to shower with!
And now the wind is up...

Tectonic comes from the word tekton.
tektōn (τέκτων) is a common term for an artisan/craftsman, in particular a carpenter, woodworker, or builder.
I should have stayed home.
I’m sorry to hear that. I hope you feel better tomorrow!
We have Mass then Cub Scouts then youth group from noon on. I’ll have to pick James up at 7:00 EST. Sally and the boy with Good Teeth are here. He has made cheesecake.
Good morning. I turned my alarm off, but was roused by Jake attacking Shannon outside the door. Unnngh.
The cheesecake was okay. If he’s going to make a profit on it, he’ll need to give it more originality somehow.
Cheesecake is not an easy thing to make in a unique and original way, probably because it’s difficult to improve on perfection. If you’ve had one excellent cheescake, everything else pales in comparison.
The boys liked it, but they’re not a discriminating audience.
Don' look while I sneekz yu.
Saw the puzzle: I’ll work on it later.
I just send them because I think they’re pretty and you might like to look at them. If you click on “Custom” you can adjust the piece shape and number and it could be something to occupy Kathleen. ;o]
Now, I have to go hang up my clothes.
Good luck! I’ll do more wash when I get upstairs again.
More appointments today. Kathleen goes for a checkup in the morning, and I have a Covid test in the afternoon, ahead of my colonoscopy which is a week from now, so it makes no sense to test me for Covid today, but whatever.
w00t!
Good morning. Happy Monday!
Today marks 3 months since puppy’s last seizure. I think we can stop reporting on that.
We will have some warmth this week, then coldness again this weekend.
Congrats on the puppy’s health. How old is she, now? (Time is a flat circle ...)
It is sunny here and might be warm later in the day. I was washing dishes half an hour ago and suddenly got a muscle spasm near my right shoulder blade. It’s super annoying!
Did I do that? Crikey. I didn’t even notice.
But thanks!
Muscle spasms are annoying.
She’ll be 11 months next Monday. Yes, she was born on tax day.
I hope that’s not an omen of how much she’s going to cost you, percentage-wise.
