This video is excellent but please tone down the disco beat as the narrator is soft-spoken and the beating in the background is drowning him out. Lower or even no background music would be great. Thank-you
So, how does one come up with the area of slip, when the focus is under water? Or when the earthquake doesn't have any surface fault rupturing? Are these found only by aftershock sequences? I always hear people explaining the equation for computing the seismic moment, but never going into detail as to how those are determined. It isn't like one can go beneath the surface of earth in order to measure the area of slip. Another thing, how do you determine mu? Do you just assume granite?
i have the same question here. i was guessing anyway if it is not for the fact that the mantle, being constitued by denser materials, is therefore quite more rigid than crust.i dont know if it is in contrast with the fact that confining pressure make rocks behave more plastic. if anyone can explain it would be appreciated
Joseph Batt I'm confused, too. Maybe they meant lower vs. higher in the crust? The mantle is a whole different thing, and it doesn't make sense for molten material to have higher rigidity than rock. Right??
the mantle behaves like a non newtonian fluid.....which simply means that it behaves differently depending on how the stresses are applied.......so for stresses that are continuously being generated it behaves plastically and makes possible mantle convections but for short duration stresses it behaves like a rigid body...........much like a silly putty......so it is both plastic or rigid depending on how stress is applied.
2:34 ... I have seen this picture before in book I used to have about California Earthquakes. The "repair" was not shown in the original picture. Is this offset fence still standing? I wonder how the property land surveyors handle this?
The fence did not move. The land on the west side moved north with respect to the east side. This was the fault displacement at that point, meaning the fault rupture was directly under the fence.
I come to learn but I end up dancing
Oscar martin quintanilla haha same
Nice presentation, but the background bleeps and bloops are utterly maddening.
WHY? :(
Great!
If you can’t explain your ideas to your grandmother in terms that she understands, you don’t know your subject well enough. =)
Thank you a lot!

Background sound should be reduced for hearing the concepts clearly....
this was so, so useful. Thank you so much
very good video - would be helpful if you explined you what the richter scale actually is and what happened to it. Thanks
I danced through the entire explanation. I'm just so curious what prompted that music choice lol

Can someone explain why the mantle has a higher rigidity? Shouldn't it be more viscoelastic, and therefore more able move?

+Julia Edwards The mantle is solid. The asthenosophere (boundary between crust/mantle) is plastic and able to flow. Allows tectonic plates to move.
Right. Because if the mantle were truly liquid, then S waves would not be able to pass through it.

Great, now I want spagetti
Good explanation

omg the background noise gives me the worst anxiety
you answered my question! Thank you.
1 million pieces of spaghetti? That's a big twinkie. (come on, Ghostbusters anyone?)
Good vid, easy to follow!
The dinosaur extinction asteroid impact event caused a magnitude 12.55 earthquake!
Thatsa lotta spaghetti...jk. But it makes sense! I think but a little confused on the mantle bit! Hmm...Great video tho!
good video!
but how far does the fence actually move?
The fence did not move. The land on the west side moved north with respect to the east side. This was the fault displacement at that point, meaning the fault rupture was directly under the fence.
How on earth would the rigidity be higher in the mantle?? The mantle is all molten material. Do they mean lower in the crust, as opposed to higher?
+Julia Edwards it is molten below the crust because of the temperature but the mantle itself is a solid
@@AngelAlita84 much higher pressures as well.
I'm dyscaculiac so I don't understand the math stuff but still this was interesting
What's up with the darn background music- I can't focus on what you're saying at all
cool
Too much bad background music.
It's over 9,000!!
Background music is really annoying.
1 million pasta?
partyyyyyyyyyyyyyyy
Bending rock .............
My teacher made us watch this in class
:/
watch on 0.5
