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.

Kitteh is sad that Tax-chick can’t eat today. Note to self: if you can’t put cream in the coffee, it might be better not to have the cheapest possible coffee.
I have “white cranberry juice,” don’t know how that’s done, and 7-up for later, to keep my blood sugar from crashing and toppling me over on my nose. I might be able to go to Cub Scouts, but DP will have to drive.
Some neighbors had a loud, outdoor gathering last night. I assume alcohol was served, because I had to shut the windows around 10:30 p.m., as voices grew more and more shrill. At least they didn’t have music on, though.
What a sad little face!!
Good morning. I forgot about the time change, but I still woke up at 0200. All the atomic clocks said 0300, but all the analogs had the right time!
My body will be fighting me about this time change until the time changes back again. Growing up, Utah was one of the few states that didn’t recognize the time change and that was just fine with me.
The sidewalks are dry this morning, and the sky is clear, and I’m about ready to start to begin to commence to get ready for church.
I dreamed about antique furniture last night. Good omen, that... at least all things in the dream considered. Hopefully, I can make some progress this week, weather allowing.
Today is pi day. I presume it’s almost pi hour.
For those whose calculators don’t have a pi key, use 355/113.
That will be close enough.
Afternoon, Bob. DP and the youth will be having pie for pi day. I will get doses of bowel-clearing sludge :-(.
To each his sown.
I think the lesson here is that even if you're the worst kind of cook in the world, you can still find a market for your wares.
That’s one way of looking at it.
Ever the incurable optimist — c’est moi.
Meanwhile, in another twelve hours or so, this will be over.
There is an ides in the affairs of men ...
Or one could just memorize the returned value of 3.1416...without having to memorize 6 digits and an operation...as was SOP in pre-calculator days.
But then again I learned that in the olden times when trig tables were used on the job.
No batteries to worry about.
;>)
I guess I’d rather have a colonoscopy than Caesar’s fate.
Well, I had a pi designation on my slide rule, too.
The 355/113 is astonishingly close to the value of pi, and that accuracy will suffice to many more digits than five or six.
Hmmm....23 stab wounds or a colonoscopy, hmmmmm let me think on that.
Eeew.
My day was over long about noon-thirtyish, or so I thought. But then, I started getting text messages from my Favorite Daughter. Unngh.
Twenty or thirty or so such messages later and I finally got up and listened to an uplifting talk as well as worked on a jigsaw puzzle.
When I came back to bed, I saw that my Favorite Son had called in my absence.
After less than six hours of sleep, I got up to go wash clothes, and now I absolutely, positively have to take a nap. Like kitteh, I’m going to crawl into a cozy spot and take a cat nap without a cat.
If I dood it, I gonna get a whippin’, but...
I gonna dood it.
