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.

Oooh, creepy!
Our local law recently caught a guy who killed a couple of people during a “house party” of about 150 people a couple of months ago.
And the noughts to you! I went for a cat picture because posting two in a row seemed shifty.
Now I have to go get into my Scout uniform, which shrank while I was drinking wine and not exercising.
You have a Traffic Circle, wow steady on there!
Have they introduced the spiral type circle yet? Or would that be against the constitution? :D
LOL!
Oops, ...:D
Ours have multiple lanes in and out, and sometimes you go around twice before you figure out where your egress is. It’s produced a few Cheated Death Again incidents with Pat.
I had an Atari 835 modem. Thought I was pretty darn cool...
W00t!!
Wow.
I’m just waiting until I can finally afford a good commuter level “flying car”...
I’ll be 500’ above all that nonsense with my kilt flapping in the breeze...
In the States we’ve a number of highway interchanges that have earned the name “Mix Master.”
This one, in Dallas, is typical:

Just. No.
There are two phrases to describe that:
1 Designed by committee.
2 Designed on the fly (move).
But if it works....
Easily,and more cheaply fixed with a roundabout at each end.
None of the traffic sat still in that picture would still be there.
Kitteh is having a hard time waking up.
Good morning.
Barking dogs and thumping noises next door. Unngh. This has got to quit. I need my sleep.
Nothing on the docket today but pill sorting (in a few minutes) and a trip to Walmart (in a few hours) and then I can relapse into “rest” until something else happens.
There has been some yowling cat here this morning. Jake likes to go outside first thing, then come in and run through the house yowling and attacking things on the floor. Fun cat.
If he disturbs others, I usually say I’m sorry, but I don’t mean it.
Oh, did I say that out loud?
