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.

Did that cause any of the stolen Trump votes in Wisconsin?
But not so fine a name for a female.
But thanks for looking out for us.
What the world needs is a tag oriented file system or TOFS.
Things don’t have folders, they have tags. A file could have a tag of “recipe” and “gift” and “enemies_list” and a knitting pattern could have a tag of “gift” and “cold”. Both would show up if you searched for “gift.” But you couldn’t do that if everything has to be categorized by folder.
Even the name could be a tag.
Good news about the puppy.
But then you have to make a conscious effort to enter a tag. The advantage of using Finder is it searches every document for a search word or phrase.
The only disadvantage is it searches every document for a search word or phrase...
Hallie Cesar?
True, and there’s no reason why there couldn’t still be a search engine on the storage medium. But tagging things to help you remember what you saved them for can become very easy to work with in a very short time.
Golly, youse guys. You almost took all the fun out of the exercise. But not quite. So there.
;oP
To: gleeaikinYou can find a freely available tool called agent ransack that will do recursive searches of text within files of directories and sub-directories. Provided your files are pdfs word processing docs, html files or the like as well as plain text, it works quite well and is easy to use. You can search the whole drive, specific directories, multiple locations, specific file types and you can also use regular expressions as well as using the wizards to help create search syntax for you and you can save your searches for reuse.
Wow. OK. Thanks, Nully. I’ll check that out!
Aww...a marmalade floof for breakfast time!
Good morning.
I think I got four hours of sleep. Maybe. Some hours are longer than others. I’ve been listening to the wind chimes most of the night, but it’s much better than listening to the plastic cover over the swamp cooler vent. I hear that, too, but the chimes are louder. :o]
The pills have been sorted and most of my other early morning jobs were done at least an hour ago, but that’s OK.
Chuck took vacation this week so my re-certification appointment has been delayed. That will give me time to get a few more documents together. What a pain.
The kitten lives in Lithuania.
Last night, I snapped the green beans for the bacon casserole, so I could make sure I had enough for the recipe. Today, I’ll get to work on sweet potatoes. We have so many that I won’t be able to cook them all at once; it will have to be several batches in the big pot.
Tom and I have a disagreement over the bacon. I suggested setting up the camp stove outside and getting out the cast-iron skillet. He suggested cooking bacon in the oven. (?) One factor will be, what else is going on with the oven.
USPS sent me another email, saying they’re still looking for my package. Right. I suspect the contents of it are long gone.
eBay has Charlie Russell’s book starting at $23, and that’s the only book that I really wanted. Maybe I can get it on payday as a consolation prize.
Gah, USPS. I mailed a box to Elen, USMC, yesterday. Hope it gets there by Christmas!
Don’t get me started on USPS...
Speaking of which, I need to go check my mail.
BRB...
Today is the Big Day: I’m dropping Patrick off at the DMV no later than 7:45, with his documentation, and he will phone when he’s done getting his license.
Go, PATRICK! I wish him luck!
And no more Driving Adventures for you until the next one is ready. YAY!!
How long will that be? A year?
All he has to do is wait in the line and turn in his paperwork, so it should go smoothly, but one can’t help being anxious.
Our current plan is that after Vlad has his 15th birthday, end of January, we’ll go to a private driving school for him and James, who will be 17 a couple of weeks earlier. They can both get learners permits, and James can take priority on the driving practice.
If he comes home with a license, I’m going to get myself a bottle of champagne.
