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’m waiting for UPS to bring me one of my dad’s paintings (from my eldest sister’s son) but I can’t stay up any longer. I’ve got the Terminal Stupids.
Mail can be so slow. I got a letter today!
Maybe you’ll get lucky and get one earlier next week!
The UPS delivery has been delayed, but it’s supposed to be here by 1900.
Now, I’ll be going to back to bed, and there could be another installment because I don’t want to sleep to early. :o|
This has been a week of misdeliveries, nondeliveries and delivery exceptions. The painting that hung in my room as a kid is now in the hands of someone else because my nephew didn’t put the correct address on it.
I am officially going to cry.
I’m so sorry.
Floofy kitteh is ready for the day.
Good morning.
It turns out that said nephew put the correct address on it so it’s the driver’s fault. Either he delivered it to the wrong address or he didn’t deliver it at all. There is nothing to be done until Monday.
I cried until I couldn’t cry any more, but this morning the tears want to come again. The box of books that my niece sent me last summer had a good number of my dad’s books in it. So I’ve lost them and now it appears I’ve lost the painting as well.
At this point, all I can do is pray. Nephew said he “will work on it from” that end, and there isn’t much else I can do. UPS is ultimately responsible.
But enough of that.
It’s 47° this morning. I can’t sit here for an hour in a wet sleep shirt!
Good morning. I’m still sorry, and I hope it gets sorted out so you get the painting.
We should already have left for Camp Grimes, but the Adult Men are running behind. I’m not going to scream GAAAAH, because that wouldn’t help, but I will walk out to the mailbox with the card I wrote last night.
So you’re leaving today and not Wednesday? What did I miss?
And thanks, by the way. I appreciate that. <3
*tagline*
This was a partial day trip. The big trip leaves Wednesday.
We’re back now. It was nice. I’m going to lie down with Jake for a while.
Ah. OK.
Well, have a nice napwithjake!
(Envious!)
I did. Jake missed me. DP and Tom when boating while the Scouts were shooting. It was all pretty fun for everyone.
It sounds like a good day, and I’m glad.
It’s cold again, being the second day of daytime temps below 70° and nighttime around 45°. I swear, I haven’t been warm since I’ve been here!
It’s also been super quiet in the ‘hood, which is unusual for a Saturday. Some days are harder for me to keep busy than others.
I’ve been looking for a birthday card for my son and there is just nothing suitable here. I can find cards for everyone else, for any occasion, but not “birthday son.” Ohwell. I’ll just remind him he’s loved by the best mom. ;o])
You can use a general birthday card and add lots of personal sentiments.
Kathleen is at her friend’s birthday party. Younger people sure throw big parties for their kids! Kathleen gets a lot of good opportunities to be a guest.
DP or a brother will go get her in half an hour or so.
Tom went home about 6:30. Saturday is his game night (online) with his high school and camp friends.
In Vegas, it was no problem to find a suitable card for my son. They were everywhere. I don’t care what kind of card I get, but he wants funny one, and he always gives me funny ones. But since I’ve been here, it’s like there is just no one in the valley who sends funny cards to their son. Weird.
My kids didn’t get invited to a lot of birthday parties that I remember. I think we moved around too much when the kids were growing up.
Strange colored kitteh from a strange country!
Good morning.
I slept in again. I need to quit that. But then, not too long ago, I was making it known that insomnia was my worst enemy, so I’ll take this and shut up!
It’s cold, being 47° and a “feels like” of 45°. The weather map says that of the four time zones, we are the coldest. Colder even than CO, which is in this time zone, but higher.
I need to go shower so I can warm up for 20 minutes. That room is too expensive to heat up for any length of time!
I’m sorry you’re cold! Good morning. It’s pleasant here, so far.
