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.

We had Envirothon all afternoon. I hope you have a good night!
I registered as Independent in NV, but I agree that seppuku would have been a more logical choice. But then, this girl is the Gladys Kravitz of the family and reacts rather than acts.
Well it started to be a good night but then I got two phone calls. I thought I had shut the ringer off but I didn’t. They were both from James and Abbie, though I didn’t have their numbers in my phone, so I didn’t answer the one from 702. I thought it was a telemarketer, but there was no caller ID. The second was from this area code - 435, so I answered it.
They called to tell me they had closed on a house and would begin to move in during this next week. How exciting for them! It’s not too far from where he grew up, so that’s a good thing.
Rocky sent me a text to tell me she was giving me back the containers I put some food in to give to her. So it’s been a busy night.
If I were a normal person, I sit up for the next three hours and watch parts I and II of Frankenstein, with Donald Sutherland and William Hurt. I don’t know how to record it for later, though, or I would.
Unnngh. I hope things work out well for James and Abbie, but being woke up by the phone is no fun.
I’m about to go to bed. I have a Spanish church event tomorrow - mostly on Zoom - and I’m sure it will be very nice, but thinking about it right now is exhausting.
It’s cold here, still raining on and off.
It’s going to rain today, and has been raining off and on since night before last. No wonder I’ve felt so icky.
I woke up to the sounds of Rocky doing some cleaning next door. Sweeping or shifting things around, or something in her bathroom. GAH!
Then the top of my left foot began some prickly-stabby things and I decided there was no sense just lying there. So here’s me.
*tagline*
Good morning. Jake let me sleep in a little! I guess he was in no hurry to go out in the rain.
Good for Jake, letting you sleep!
Some days, we need to do that.
I took out the trash (three bags, two of which were filled with items that were out of date) and then sorted through the file tubs. I need to get more hanging files, but that will have to wait for payday. Darn it. I was on a roll!
I would have been here sooner but I listened to a talk that was about twice as long as what I usually listen to. It did give me a chance to start and finish a puzzle, though!
I’m having some breakfast. Then I’ll do my prayers, and then make song pages for today and tomorrow and Ash Wednesday.
At least it’s just rain, not ice and snow!
Kitteh must think the world looks better sideways!
Good morning.
The lack of sleep is trying to catch up with me. But I’m determined to get something packed today.
Right now, I need to go make the bed and say my morning prayer. Then we’ll see what happens next.
Best wishes for a great success to both of us!
Favorite Daughter is having -2° at the moment, and an AA friend of hers in Canada is at -30°. I count my blessings.
The bed is done, and the prayers, and a little sorting for donations, again. I’m actually trying to make room between me and the bookcases so I can pack some books and store the boxes on the bottom two or three shelves.
Maybe I’ll even get something packed in the kitchen. Besides the plastic containers, that is!
Yes, indeed, but please, don’t overdo it! Give your body time to recover from “The VID.”
I need to shred the rest of the papers, today, too, and get the mess out of my way. Little by little, I’m making a dent in this mess.
The weather is conspiring to keep us all pretty sedentary.
I’m reading “Tent Life in Siberia,” about American explorers in the 1860s. New perspectives on coooooold.
I’ve been BIZZY!
One bookcase is sorted (not packed, just sorted) and the kitchen spice cupboard has been emptied and inventoried. I won’t seal the box, as I still plan to cook, but I also have two boxes of stuff set aside for mailing.
- - -
Four boxes of fiction for donations. The stack is the biggest yet. I’ve made progress!
So, I’ll take my next batch of pills, rest a bit and then turn myself to shredding. After that, who knows?
You’re my inspiration! I almost have my pages ready.
