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.

Good morning...
Observations on local critter populations.
Sudden appearence this late summer of numerous black squirrels in my immediate area but also in the surrounding ones in about a half mile radius. Is this happening anywhere else?
A black Angora bunny has been using the potting shed as an occassional refuge in the past few weeks...poor thing appears to have fleas and matted coat. No one has posted a lost bunny flyer yet. Might have to photograph and post found flyers.
I have not noticed black squirrels or angora rabbits.
The yutes and I have done a Spanish lesson. Next thing will be my WW meeting, followed by a Patrick Driving Adventure.
A ‘Face Driving Adventure was just had. It was almost a Misadventure, as I was blinded by an oncoming utility truck as I rounded the first bend from Walmart by the fire station. Scary.
No black squirrels or angora rabbits here, either.
We were locked out of Walmart for seven minutes. Or maybe it was nine. The person who was supposed to be on the door doesn’t come in until 0700, so had it not been for a smoking Walmartian, we may have been out there for another hour. I bet that won’t happen again.
Monday morning our furnace decided it was a good time to die.
What makes this a particularly joyous occasion is that it's 23° outside right now.
We're having something of a cold snap, first available furnace repair appointment is next Monday.
Good thing we have a wood stove...
w00t! again.
Yes, cold weather mayhem has struck here, as well. While four of us “seniors” were waiting for the doors at Walmart to open, the subject of yesterday’s cold, brutal wind came up; how it knocked out the TV and internet both, to 2700 homes.
Not nearly as bad as losing a furnace, but most people here have wood stoves or fireplaces. I won’t be warm again until summer, wherever I experience it!
I’m sorry you have to go through this, Nully.
Thanks!
It was just hanging there, waiting for someone to use it, so...
Found - black angora bunny
If you are voting/voted for Trump call ...
If you are voting/voted for Biden call ...
Make ‘em guess which one will get their bunny returned safely.
Humans don’t get to pick and choose, either when they die or when their stuff dies.
Often true.
Sharing something that made me chuckle out loud. (is col a thing?)
Attempting to have a foot in the buckets of both pro- and anti-fracking sentiment left him [Biden] in an unpopulated DMZ, between the dog and the fire hydrant.
I will chuckle if he doesn’t get away with it.
Back from the Driving Adventure. Pat generally does fine on the turnpike.
I like turnpikes. Even though the speeds are fast you generally have good visibility and, except for the occasional varmint, things that behave as you’d expect them to.
I hate driving in neighborhoods. You never know WHAT a child, dog, cat, squirrel, or angora bunney will do next.
Even 10 mph can be challenging.
;>)
I have to be careful about reading Twitchy when I’m supposed to be paying attention in a meeting.
Apparently, Biden (or one of his minions) tweeted, “In 8 days we’re taking our democracy back.”
Nigel Farage replied, “And then sell it to China?”
Good think I was on mute and didn’t have liquid in my mouth.
Lol!
Life is full of surprising risks.
So how was your WW meeting? Is it still virtual?
Kate wants a Driving Adventure to my doctor’s appointment tomorrow so we can stop at the thrift store on the way home. I’m a nervous passenger, so I’m not sure how this is going to work out.
(Crikey, I’m tired!)
LOL!
That’s funny!
I’ve been trying to stay away from politics for the last few days.
Yes, still virtual. It’s good to see people’s faces, at least. I dropped Pat off at work and Vlad and Frank near the Dunkin’ Donuts. They’ll walk home.
