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 think I’ll have a shower before I go to the library. I don’t feel like enduring a Driving Adventure today!
I just texted Tom about getting me some things from Amazon, so maybe he’ll tell us how he’s (ahem) feeling today and whether we should expect him on the doorstep.
And yet, another light bulb went out. This time, on the desk. I need to put light bulbs on my grocery list because I am now down to three new ones.
This place is driving me to distraction.
Physics: it wants to drive us mad.
We’re about to leave on a Driving Adventure to the library and bank. Pat needs to deposit his birthday check from Grandmama.
And we have returned safely. It is quite nice outdoors. I wrapped Pat’s Christmas gift for Vlad.
This has been a day I don’t want to keep in my Dates to Be Remembered stash. I just want it to be over with.
So I’m going to the library now, and will answer the FReepmail when I get back.
First of all, you've gotta be willing to lay eggs.
I don't see that as a problem for either of us.
Afternoon, Bob. I knew a wit would appear if we were patient!
I’m not completely witless, so I’ll just put off going to the Post Office to mail a book to Elen until next week.
Just imagine! A whole country, and possibly the entire world, coerced into taking shelter in the Witless Protection Program.
Maybe they’re all waiting in line at the Post Office.
Good heavens, is it only Wednesday? It feels more like January.
Happy Wednesday, everyone.
It is Wednesday. I checked the calendar.
Good morning. I hope you and the Mrs. and the puppy are flourishing!
All is good this morning, thank you. The puppy is moving back to regular food and taking it well. And we had another seizure-free night. Soon we can start counting weeks.
Wouldn’t it be great if the seizures were just a strange, unexplained episode that never happens again!
If they never happen again, we will probably blame the 12-week heartworm pill. But, yes, it would be great.
Ah, pets.
Ah, vets, actually. Give them an insecticide to eat to kill heartworms. OK, it’s a small dose. Give it to them monthly with a dose designed to go up to 45 days (or longer if they’re at the low end of the weight). Give it to them year round even though heartworms are only a danger during mosquito season. Then up the power to last 12 weeks and wonder why problems start happening.
Oh, and give a medicine with a slight side-effect of seizures to a breed with a higher than normal incidence of seizures. That’s DVM.
Very unfortunate situation.
Happy Friday Eve!
Happy Christmas Eve!
I know, Kitteh, I can’t believe it either.
I hope everyone enjoys the day. I’ll be working for a while, but I’ll knock off early.
And another night with no seizure.
