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.

I have been hot, maybe not quite Guatemala hot, but very hot.
The castles in England are higher on my list.
I’ve been up since 2345. Unngh.
The bed is made and the pills are sorted and that’s it for now. I need to go fold the sleep shirts and put them away. Then, there’s the Walmart trip.
There’s no indication that I’ll be able to pack today, but I will tomorrow, for sure. If I pack anything today, it will most probably be books. Which sounds like a great idea, and I just may do it after my next dose of morphine. I’m so glad I have that drug! At least now I can DO things!!! :o])
Missouri, Arkansas and Louisiana are Guatemala hot, and it won’t be long before I can experience it again. D-i-L seems to think I’ll suffer in AR heat, even though I spent three years in MO with no A/C. I don’t ever remember being dry. I got used to it, but I didn’t like it.
Kitteh and his astounding whiskers live in Scotland.
There. I fixed it.
Actually, I made a mess of it. I meant to write “Handsome” instead of “Astounding.” I need to go back to bed.
Good morning. If you’ve gone back to bed, I’ll say good morning again later!
No, I have to leave for Walmart in about 30 minutes so there was no going back to bed for me.
And I want to pack something when I get back, so bed will have to wait until this afternoon.
Well, good morning! It has stopped raining here for now.
I’m going to the podiatrist later this morning.
You’ll have to let me know that trip to the podiatrist turns out, please! I hate achy feet!
Now, I’m out the door!
Good luck!
Good morning. Happy Tuesday. Back at it all again.
We had ice overnight. It was raining when I took out the puppy this morning. She didn't seem to understand that we should go slowly on the slippery parking lot. She wasn't too much trouble, until she saw the other dog. Unfortunately, it was near the pet waste container so we had to go that way.
I survived. No fall. Not that she didn't try.
I’m glad you didn’t fall. Something to be alert for the next time!
Unngh.
I got what I needed and was worn out before I even got to the register. I used self-check today because my Walmartian friend was there. I haven’t seen her in ages, so we talked. Well, I did, she’s got laryngitis. Anyway, it took me longer than usual because I was so tired.
So here I am. At a standstill.
Good morning.
Sorry, I’m not functioning on all burners this morning. And I think my thinker’s busted into the bargain.
I’m glad you and puppy are safe.
Back from the podiatrist. I have plantar fibroid - that’s the lump in my arch - and tendonitis. He’s going to prescribe anti-inflammatory medication for the tendonitis and also an ankle brace. They’ll email the information so we can save money by buying it on Amazon instead of through the practice!
Also arthritis, but that’s not what’s causing the problems.
Well, it’s a relief to know what has been causing so much pain, and I wasn’t surprised by anything except the plantar fibroid. I sort of suspected tendonitis, as it’s something that comes along with sports. And you’re a sporty kind of gal!
Excellent that you can get the ankle brace on Amazon. Medical equipment is always too high-priced, no matter what. But again, if you don’t mind, I’d appreciate you keeping me informed — when you start to use and if it helps. Just curiosity, so if you don’t want to, you don’t have to!
I came through the hallway and thought I wanted to pack some books, and even just looking at them wore me out, so I think tomorrow will be a better day for it.
Sure, I’ll let you know how it goes. Sorry you’re worn out already!
Thanks for keeping me informed and thanks for the commiseration. The fatigue is why this disease is so insidious. I have a tendency to do too much when I feel good, and that means I need to rest at least a day between efforts.
I’ll try to pack for an hour tomorrow, and hope that doesn’t set me back too far. Although, with getting up before midnight, then going to Walmart today, I may not even make an hour tomorrow.
