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 looks like a tiny squeeful kitteh!
Good morning.
I think it’s Wednesday. I got everything done but going to the bank for laundry money, but I can do that any time before Friday.
Maybe I’ll get the new ink cartridge installed today and get stuff ready to be mailed. No promises but I need to do “desk jobs” today.
Good morning! It is Wednesday here, if that helps.
Jake spewed again. It’s almost as if he understands English: having been told, firmly, to spew on the tile instead of on the carpet, he did ... right in front of the coffee pot. GAH.
Oh, dear. Poor Jake. I’m sure, after all these years, he understands more words than you think. Unlike dogs, cats are selective in what they wish to do.
I saw a short film a long time ago about how a guy from some Eastern European country had trained a bunch of cats to do things like walk tightropes and climb ladders and one even rode a kitteh-sized bicycle.
Jake, spewing on the floor instead of the rug, indicates that he loves you and doesn’t want you upset. For what its worth, anyway!
I’m trying to make a journal entry and it isn’t easy. So much has happened in the last two weeks. Where do I start? :o|
In the meantime, I think I’m going to put some ice on my knee.
Sounds like a plan. James is complaining about his knee, too. Maybe it’s contagious!
Here we are on Wednesday. Happy Wednesday, everyone.
Try re-reading your posts here. If you don't have the entries, you at least have the reminders.
Thanks for the suggestion. I should do that with every thread I’ve ever posted on since I joined back in 2001. It would help with some things, for sure.
I told my Favorite Daughter that I’ve saved all of the letters I’ve ever written to the hard drive, and printed up emails to and from her and my Favorite Son, but some days, I can’t remember where I wrote something. Of course, if it’s on the Slave, it can be recalled when needed, whether a journal entry or a letter.
Happy Wednesday! Again. Is it summer, yet?
Officially, it’s not even winter yet. Thank you, I’ll be here all week.
I used my posts on UT to figure out when we’d been on Patrick Driving Adventures that he hadn’t bothered to write in his training log.
Nice to know we’ll have a kitteh the rest of the week, and that you won’t have to take time out from your busy comedy routines and Pat Driving Events. Or are they the same thing?
I’ve used the UT to recall what I’ve said because CFIDS. I often use the private messages I’ve sent to know how to respond to the answers I get.
Looks like we’ve all used it to our advantage at some time or another.
When I look outside the window I see a light dusting of snow. So the answer is “Yes, in Australia.”
Golly! You’re right! I need to go there! :o]
Never been to Australia, myself, but it looks nice in pictures.
I will probably have a Pat Driving Adventure later today. On the other hand, I may chicken out.
I’ve always wanted to go to Australia, and of course, New Zealand and Tasmania. But...my budget only allows for travel films.
Good luck on your Pat Driving or Not Adventure.
I want to go to the ISS so I can see it all.
Yes, as would I, it would be a little difficult for a Walkabout from there, don’t you think?
Yup.
Looks like they’re aiming for mass disabilities in the populace.
Bell’s palsy..lovely!
‘sok by me.
