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.

That is an issue, and how people who start out fostering kittens end up with 40 cats.
I’ve decided to do a trial run to Walmart pick-up tomorrow. My time slot is between 0700 and 0800, so I’ll try to be there on the early end of it. I put down “no substitutions” because they already have a list (in livid color) of what I buy, anyway!
So I had to re-install the app on my phone, but if it works, then good. Now, I need to make a change to my U-Haul plans.
Good morning. Happy Monday.
Busy weekend here, but we’re back to busy work week.
I put the puppy out in 6 fs this morning. Brrrr.
fs = feet of snow?
Degrees Fahrenheit, I think.
Happy Monday to the new arrivals. We’ve read two scenes of Henry VI: the famous one where the sides pick roses to choose up for the death match, and the death of Mortimer, who is a composite character of two Edmund Mortimers, uncle and nephew.
Good Happy Monday, ArGee and Nully!
Six fs sound positively frigid!
And all I’ve managed to do is laundry and nap. Oh. And get a grocery order put in at Walmart, and made a call to U-Haul. Unngh.
I’ve got a glitch in my upper spine this morning, and the wind is beginning to blow. The sky is overcast. Again. Or maybe still.
We did more reading and watched videos of Kamchatka, which is scenic.
I loved when the Wild Russia series did a segment on Kamchatka. It happened that there was an earthquake during the filming and they just kept going!!
I’d love to have that entire series of Wild Russia and the one of Wild China. Fascinating!
I’ve seen that before. Remember Noah had the best design engineer.
Also, I heard a talk about some of the things they rushed in the Titanic so it could make an important sail date.
Project Managers never learn.
No. It’s some kind of temperature gauge. The other popular one is Cs
Your upper spine can make the wind blow?
THAT is COOOOOOOL!
My spine holds my head up.
Michael Palin toured Kamchatka, too. It really has spectacular volcanic scenery.
Come to find out on the spine thing, it was actually my heart playing tricks on me. A shot of nitroglycerin spray took care of it. Along with a couple of coughs to get the heart to stop what it was doing and begin to beat properly again.
I checked with the library to see if they had the “Wild” series but they don’t, so if I want to see any of them again, I’ll have to buy them through PBS. Darnit.
Sweet little kittehs! Yesterday’s and her bruvver?
Good morning.
I saw that my ink was delivered, so I headed out the door to go to the clubhouse, and there’s about an inch of snow on the ground. Since it’s still very cold out, my feet crunched almost all the way over.
I’ll have to do a very good job at cleaning the car windows before I head to Walmart. It looks like the stuff fell straight down, so it’s on all them.
The pills have been sorted, and I need to gather up the documents from last week and make copies so I can send them all to another housing authority. Just in case. One of them is bound to open when I need it!
With luck, I’ll get it mailed out on my way to Walmart. I have until February 4 to get it mailed.
Sounds like you’ve been busy!
Yes, that’s yesterday’s kitten and the day before, littermates.
Be very careful in the snow! It’s raining here.
