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 imagessimilar 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.

Nope. Just noticing the kitteh that is being flattened into a rug.
Kittehs are closer to the ground than we are, so gravity pulls extra hard on them.
I need a shower, but I’m afraid James used all the hot water.
It is still fall...
I’ve always been interested in those heat exchangers that can be put in-line at the point of use to give instant and continuous hot water.
I don’t understand why they aren’t in more regular use.
Maybe it has to do with deposits building up in the exchange coils. But you’d think someone would devise a system that allows for a rapid replacement of those coils - kind of like air filters. It seems the power savings and instant-on heat would make it worthwhile.
If you already have a standard water heater, replacing it with a tankless one is super expensive.
I just sat around in my bathrobe an extra hour.
What did I ever do to deserve this Wednesday?
I have been going non-stop since I got out of the shower at 0358, and I’m not done yet. I have to go back to the office when Chuck has done the maths on my recertification to see if my rent is reduced at all.
Not holding my breaths.
The wind is still going, and the Lawn Guy has given up for one more day. He’s blown off all the leaves on all the lawns and sucked them up into his leaf disintegrater except for the first three buildings on this side of the street. Arrggghhh.
Unnngh.
I’m going to have a nap with a cat.
I want to sleep, but I’m still trying to wind down. It’s been a day, so I’ll be here for another little while.
I had a nap, but the cat was annoyed and got in his own bed.
And that’s it. All of a sudden I ran out of steam.
ManaƱa.
Adios!
I don’t know what “super expensive” is. I know what happens if the water heater erupts. I also know the cost of keeping water hot when nobody’s using it.
Oh, well, it’s something to look into when I’m living in my own house again instead of an apartment.
Trying out a new tagline...
Cute!
We’ve never had an eruption, and natural gas is very cheap here.
It would seem that we are one of the very few countries in the world to use hugh water heaters that take up space and heat the room they’re in. Most other developed countries use on-demand water heaters and have for over a century.
It would seem to me that one of those would be cheaper in the long run, but only ever owning one house in my entire life, all I can go by is what I see and hear from other people, and from my experience in Germany.
Good tagline!
I like Orange!! ;o])
Kitteh sez it’s Thor’s Day, all day! So there!
Good morning.
I just swept the floor and in a bit, I’ll swap out the black ink cartridge in the printer. Sometime today through Saturday, I’ll get the Christmas cards ready to mail, and take them to the post orifice on Monday.
I’m not happy with iHerb. I put in the order on the 27th, thinking I’ll have it by Monday of this week, but the “2nd Day” delivery only applied to one item, which wasn’t delivered until Tuesday. There was nothing on the website about the bulk of the order (16 items) except “Fulfilling” when I checked on it.
When I got up last night, there was an email that it had been shipped and would be here the 7th. Are you kidding me?
THIS time, I not only told them I wanted a refund of the $4 I paid for the order to be delivered the “2nd Day” but I also wanted an explanation why it would be almost two weeks before I actually got the bulk of my order. Don’t anyone take a BP reading on me right now...
A lot of companies are having trouble getting deliveries together because of Covid. Decent ones are honest about it. I put an order in with Dover yesterday, and the website said it would be up to a week before it shipped.
