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.

Agreed.
Tom came by and borrowed a muffin pan and accepted a gift of a stick of Crisco shortening. He’s going to make extra-large “brownie bites.” He may come over tomorrow for the early celebration of Frank’s birthday, which is really next Thursday but we’ll be on the campout, which means no ice cream.
Let's see if this works...
It worked. My uncle used to have a colony of polydactyl cats in his barn in Buffalo, NY. I should call my uncle. (He’s a social uncle, my late father’s best friend from flight school in the 50s, not an actual relative.) He called last year at my dad’s birthday and left a message, but I was in a whopper depression at the time and didn’t call back.
How are you? Had snow recently?
Supposed to be 80+ tomorrow and Saturday though.
I found a "You Laugh, You Lose" thread on another forum and they had some funny gifs... The cat ones made my think of your Daily Fur baby posts...
Just sayin'...
Yeah, that’s funny.
Our Jake is being stalked by a pair of brown thrashers who must have a nest very nearby. They even yell at him when he’s indoors.
Happy Birthday, Frank!
Hi, Tom!
We’re DOOMED! Opposable thumbs!
That IS funny!
Now I’m going back to bed. I had to get up and give my back a rest. I was sitting in a very awkward position.
I think the Thrasher Incident is hilarious!
Tom came and went. Frank’s unbirthday will ring the welkin tomorrow.
I hope you have a good night. The thrashers in our face are new this year. Tom the Mocker has gone nose-to-nose with Jake in the past, but wherever he has his nest this year, he feels safe.
Not if we can convince them that helping wash the dishes is the pinnacle of cat awesomeness...
G'night Face... I hope your back feels better.
Funny!!
Thanks!! The back feels not quite as contortion-y this morning. The problem is that I didn’t change positions when I should have. My bad.
Oh! Look! A dish cloth to sleep on!
Good morning.
Off to the shower. Here’s hoping it wakes me up!
Good morning. Enjoy!
Done. Awake. Kicking feebly. Not stirring up much dust. Maybe later. Unngh.
I’m going to write to Charlie, then see how the body feels.
I have to be sure, no matter what else gets done today, to call AAA.
I have rousted the Youth.
