I with the US Geological Survey said -- earthquake with a half a mile deep and centered about forty miles northeast of Richmond.
So then how come people from Georgia really doubling in New England over to Michigan even all felt the after effects.
Steve -- shock is a professor of geology at the University of Illinois professor I don't even know where to Begin OK so.
And what we understand the -- center was in Virginia.
There happened to be a number of faults that run along the east importers United States speaker -- breaks in the crossed that actually in this case date back a couple hundred billion years -- -- related to the -- Opening of the Atlantic Ocean but once -- they stay is weak so there's sort of like scars that never heal in the -- and over time stresses build up on these halts and essentially what a while they move.
And what we have today was a situation where one of these long lived long lasting we called just suddenly couldn't take it anymore and slipped.
This actually was an earthquake zone rates so this is a really active area and then it it.
-- is that well I have to -- 200 million years.
I'm start near 202 to 300 million years ago let's be clear back on -- that is very -- as I guess if so OK so then.
All -- tension is is growing and building what we released it to make this happen today.
Well the occurrence of earthquakes and particular halter are sort of random.
Offensive it's impossible really to -- particular earthquake to particular places in India but -- -- to any level of confidence and effectively what happens it is sort of you know what could stick that you start to bend it and then you can't really say exactly what it's gonna break but it does at some point that's probably what happened on the salt.
But sir is what size Scientologist do they track this -- and they follow -- -- been able to even give a little heads up.
No I don't it's psychologist major earthquakes and -- understand quite a bit about what physically happens during in the earthquake and and how earthquakes caused damage.
They've been working for years trying to understand this is a way to predict.
Specific earthquakes but really so far it doesn't seem like like there's a way to do it -- earthquakes -- to some extent a random event just like a hurricane hitting a particular point on the continent some random.
-- -- My seven year old daughter so let's talk about now why it was so wide range why -- Offices in Connecticut were evacuated all the way down to Georgia how could that eat.
Well it's because that that nature to crest in the eastern United States is is different from say in California.
Wanna say -- -- -- randomly doesn't mean that they're evenly distributed to -- the world -- specific regions where earthquakes happen all the time in California is one of them -- -- plate boundaries where one piece of the outer -- of the Europe is moving relative to another piece Batiste United States is actually far from a plate boundary.
So -- the -- it's fairly strong and it kind of is so strong that when you.
You know I'm inject -- energy into one point that energy can travel long distance much -- in the can see considered quick California.
If so are basically what happened to your -- happened in Virginia but the energy travels in the form of waves just like rippled -- upon around three to crest at a speed of about six kilometers per second that's about three and a half miles per second and will be felt for some distance to finally it fades out.
And probably in this case that the distance -- -- was a part effort to be felt in New York.
Up in New England.
And sort of we out into the mid west and also down into the Carolinas.
Professor -- -- let me tell you I wish I took your course in college because I understood every word you said and it made sense thank you so much for explaining --
