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 imagessimilar 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.

For painting half a wall?
Does it matter which half is off?
It depends whether you’re right or left handed.
Think about what it was like when you were hot!
DP was just looking up a possible site for a future campout and found a sinkhole swallowed part of it.
Oh what luck!
Saves having to dig a latrine.
I think about that all the time. The difference being, in Henderson, I could sit in the shade, with a breeze and talk to Charlie and whoever else was out there. Here, there is no shade where there are places to sit and there is no one to talk to.
I have to keep the A/C on for the laptop, printer, router and slave. So my choices are limited.
I love the heat!
That’s what happens when golfers gotta golf and developers gotta develope. The aquifers are hard to refill when people keep taking the water out faster than the rains can refill it.
That’s too bad. I hope DP was able to find somewhere else that’s all there!
He was just poking around, not working on a particular plan.
Ah. OK. Well, I’m headed down the hallway. I have no clue why I feel the way I do but I hope tomorrow is a better day!
Have a good night, and I hope you sleep well!
I hope tomorrow is a better day for you, and I hope I sleep well! We have choir tonight, but everyone wants to go home well before dark, so it won’t be a marathon like the volunteers’ Zoom meeting.
In the time it took to answer a Freepmail, BOOM! Breakfast kitteh!
Good morning.
Did you sleep well? How did your choir go?
I forgot to text my cousin with my address. He’s in Logan, now (close to the Idaho state line) and has internet so he wants my address and phone number again. There’s my solution, right there: Ignore him, and the whole thing is over with.
Choir was fine. The new song came together well, and we were finished before 8:00, plenty of light left for people to get home. I went to bed before 8:30. Tom was out on the back step chatting with Elen, USMC, on the house phone, but I couldn’t stay awake.
Tom took Vlad to Your Local Game Store to buy the cards he wanted, and Vlad was up until 10:30 listening the most desirable ones for sale and watching his bids.
“The website says this one is worth $140!” said the entrepreneurial youth. “Not until someone offers you that much,” I replied.
As my late father used to say, “What’s a sick chicken worth? Whatever someone will give you for it!” He had a one-legged chicken as a pet when he was a little boy.
I’m going to have Vlad watch the “Intro to Investment” series on The Great Courses, and then his grandmother will set him up with a brokerage account.
How are you today?
I’m seriously considering asking my cousin why he’s coming. If it’s because he wants possession of my late aunt’s journal, he can save himself a trip. It’s not leaving my hands until it’s transcribed, and then he can have a copy as well as the original. My feeling is, if she had wanted him to have it she would have given it to his dad.
But I only know Blunt when I’m like this and not Diplomatic.
Outside of that glitch in my processes, I’m not too bad, emotionally. Physically, meh. Mentally, the jury is still out.
I may have a visitor this morning who isn’t Sharon! On of the gals from another ward. I used to see her all the time before our ward grew and had to be split. Now I see her mostly going one way down the street and I’m going the other.
It sound like Vlad needs the “Intro to Investment” course. If he’s any good, he could be an independently wealthy man by the time he’s 25.
How is Elen, USMC doing these days?
It must be interesting having a lot of cousins. I have only two. I’ve always been friendly with them, but they’re much older, so it’s mainly a Christmas card and what I hear from my mom.
It only takes one good play in the market to be set up for life, but most traders never hit the jackpot. We shall see!
I’ll have to ask Tom how Elen is. I assume we’d have heard if she suffered anything worse than boredom! Maybe Tom will be over again this weekend.
I used to think I was related to half of the town I grew up in. Come to find out, I’m related to half the county as well as towns from Mexico to Canada. One of my grandfathers had a wife in Canada and one in Mexico and each had ten kids who all lived. (This was after polygamy was abolished in the nation, but he already had the wives, and he couldn’t abandon either one, since the children were all his.) I’m going crazy with all the genealogical information I have to collect and distribute.
When I was growing up, we used to have family reunions and filled up the entire park, which was pretty hugh for such a small town (4,000 peeps) so I never new most of my cousins to spend any time with. Mostly by face, and then of course by name. “Oh! You’re related to the ....! Hiya, Cuz!” Kinda thing.
So yeah, I’m going to email him and ask him why. To be continued.
What’s happening in your neck of the woods today? Any outings? Or visitors planned? I’m finally answering some letters!
Vlad is anxiously tracking bids on his cards He’s hopeful! He could get a windfall as the weekend progresses if the greater international Magic community fixates on one (or more) of those cards as the best ones in the new set.
Kathleen did her swim test for camp and qualified as a Beginner. It was a good effort. It doesn’t really mean anything in terms of what she’ll do at Day Camp or WAC, but she now has a higher rating than any of her brothers, who did not test and therefore are non-swimmers by default.
It appears to be a high stupidity day out there: I had encounters with bicyclists and walkers (!) who seemed to believe motor vehicles are just fake news created by the patriarchy, or something.
DP and Frank have gone to the gym. Not sure what we’ll do when they get back, other than lunch. It depends on the forecast.
Good luck to Vlad! I hope his excitement lasts until the last bid is in! And that it’s worth it!
Good for Kathleen!
That Stupidity Syndrome seems to be highly contagious. That happens to me when I’m in the BB SUV — I’m suddenly not a threat to anything on the road and therefore, I don’t have the right of way, even when I do!
Speaking of the BB SUV, the plate is wrapped up and ready to go. If my visitor shows up early enough, it will go out in today’s mail. Otherwise, it will go out Monday. There is a letter in it as well. I hope I remembered to sign it...
If you didn’t sign it, I’ll never know who it was from!
I was sitting out in the yard with Tom and Kathleen when Weather arrived. Fortunately, I had brought my painting in before Downpour.
I painted a sunflower.
