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’m so sorry about your poor cold feet! You need one of those fuzzy foot warmers.
Night!
Thank you, I will look into those!
If I ever get to the point where I can actually feel something in more of my feet that just the soles, I may get something like that.
For now, I’m happy when I can feel texture or temperature on the soles. The rest of my feet are numb to the ankles, so instead of going barefoot, as I’ve loved to do since I was a kid, I’ve had to learn to wear socks to protect my feet.
My TV just decided it didn’t want me to change the channel so I don’t know if its the TV itself or the remote. I unplugged the TV and waited a minute and turned it back on and I can at least change the channel, though i can’t see the channel line-up. I don’t know how long that’s going to last, but I’m thinking all electronics are built to be disposable. There’s more money in it that way.
Ai not biting bruvver.
Electronics are a tool of the devil to drive us mad.
Good morning. It’s raining here. The cats got wet. We’re supposed to get our new back door today.
Floofy morning kitteh sez da bruvver isn’t complaining.
Good morning.
Just had my shower, and after eleven (I think) hours of sleep, I feel not too bad this morning. Not great, but certainly much better than the last few days. It’s 24° outside. It will be colder just before the sun comes up.
I think Jake went upstairs and raised a ruckus at the sleeping-in folks.
Yes, but at least the TV has voices on it besides my own.
Wet cats are fun to watch when they lick themselves dry.
Congratulations on the new back door! Is it the same one that was on it’s way to a massive breakdown when last I visited?
Remember the U-2?

I think we replaced that screen door with a different one. This time, we’re replacing the whole thing, both the opening part and the part that was just a window, with a sliding door.
I don’t actually like sliding doors, but it would have cost twice as much to replace it with a similar setup.
Yes, I do. I mean, as a concept, not personally.
DP says he’s going to call the installer and see if they want to reschedule, since it’s pouring.
I remember the whole thing. The Russians got a real prize when they were able to shoot Francis Gary Powers down. (And to think that he died in a helicopter crash.) We all knew WW III was just on the horizon.
12 fs when I walked the puppy this morning. She didn’t seem to notice.
Good morning. It is now Wednesday. Sometime this afternoon or evening we should get that nor’easter that’s coming our way. Or not. And it will have gobs of snow. Or not.
F-I-L has his prostate procedure today. He’s a bit nervous about it. Mrs. ArGee will be with her mom until he’s back at home.
We need rain here, because of orchards and cattle, but as long as we get snow in the mountains, we’ll be OK.
Maybe the installer likes the rain. ;o]
