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.

The video at the top shows giraffes running.
And James is a whiner. It’s probably a survival adaptation relating to Tom, Pat, and Vlad all being so smart and tricky.
Good morning, all. Happy Friday Eve!
We are looking forward to light snow through the weekend. So far nobody has lost power, at least not so it’s made the news.
I had to turn off the sound on the running giraffes. I’m not into hearing people scream so early in the morning.
Wellden. James should enter the military, where I’m sure he’ll find a lot of less smart and less tricky people around his age who have similar home situations. Not only that, but if he’s assigned to the motor pool (both my kids were, though one was in the army, fixing vehicles, and the other was in the navy, driving them) where they will teach him to drive.
For some reason I am reminded of a Monty Python sketch. The theme of the show as anagrams. In this particular sketch the man in uniform was standing outside an office door. The sign next to him said MARY RECRUITING STATION in removable letters.
Someone walked up and asked to talk with him. He invited the gent indoors, then said, “Wait a sec” and rearranged MARY to read ARMY. Worth a chuckle.
Good morning.
Friday Eve, it is.
No snow forecast here, but most of our snow has been forecast as rain, anyway.
Monty Python and Benny Hill. The best of British comedy.
It might be a good idea for him. We’re also looking at possible jobs in the tree-service business, but it’s possible he would have to be 18, which is almost a year away.
Cute!
At any rate, it sounds very much like James is ready to “leave home” and start making some major decisions about his life. Good luck to him.
James will be good at any job he has a real interest in, and will excel in it. So good luck to him!
It’s hard when they are 17 and have almost no options because of rules about “children.”
Exactly, and some are ready sooner than others, but the indications that they’re ready are pretty similar. Seventeen is a very awkward age — not a kid but not a man. Favorite Son entered the army at 17. It served him well, because he’s seldom been out of work, since.
Strange, in’it? Someone somewhere threw a dart at the board and decided 18 would be the age of majority. But no 2 18-y-o children are the same. Some could be trusted with a contract at 15, some can’t be trusted at 25.
Yes, they are all different. James isn’t ready for independent life, but he’s not going to be any more competent to follow directions and use tools (the requirements for working for a tree-service) just by being 11 months older.
Interesting, I do a crossword puzzle every day in an app on my phone. I just realized there’s never a cross word in any of them.
Well, IIRC, we’re all ready for independent life before we’re ready for independent life. I think if most of us really understood independent life when we were 18, we would live in our mothers’ basements until at least - oh - 95.
Funny! I did the WSJ crossword during lunch.
Truth. I was married at 17, but by the time I was 23, I was “older” than my husband. He wasn’t any older at age 65 than he was when we got divorced, meaning all the responsibility he had shirked in his younger days was still waiting to be recognized and dealt with. Didn’t happen.
The good thing about the military is that they find out your strengths, send you to school and advance you when you’re ready. Thirty years as a military wife, mom and grandma taught me that much!
I haven’t been doing many crosswords since I moved here because I was having a hard time with word substitution. I was doing them in Henderson, but after a couple of months here, I just couldn’t do any but the simplest. I’m sure now that it’s the mold in here so I’m hoping the DMAE will help me.
Jigsaws are the only puzzles I do here. When I’m in the laundry room I do some word puzzles but they don’t have to do with word substitution.
Yeah, that’s a thing that happens.
