Question

Name the geologic feature in South America that is responsible for very strong earthquakes.

Medal and fan who gets it right in 24 hours.
Hint: 2010

Answer 1

I'm pretty sure that earthquake was caused by the one plate deciding to go underneath the continents plate. I think?

Answer 2

Give me the specific name of this geologic feature.

Answer 3

Would it be fault line?

Answer 4

Tell me the specific name.
Ex: San Andreas Fault, Himalayas Mountain, Mariana Trench, if it is a plate boundary, you can tell me which 2 plates are interacting with each other instead.

Not a fault line btw.

Answer 5

It's been quiet sometime since I even took a look at any of this stuff lol

Answer 6

Would it be the Nazca plate and probably another plate that I don't know lol

Answer 7

All I can say is "almost"

Answer 8

It is important to know if you live near an earthquake plate boundary zone.

Answer 9

The Chile triple junction is the only modern site on Earth where an actively spreading mid-ocean ridge crest is being swallowed by a subduction zone at a continental margin. This is a particularly interesting area to study because we can observe two types of plate boundaries (divergent and convergent) and their processes in very close proximity.
I found this does this have anything to do with it?

Answer 10

A triple junction occurs when 3 plates boundaries intersect, leading it to produce 3 different geologic features.
Ex:mid oceanic ridge is one of the 3

Answer 11

Good to know

Answer 12

Another example is the triple junction in northwest USA, where North American, Juan de Fuca, and Pacific Plates meet. It produces very seismic active earthquakes and volcanoes.
The 3 are San Andreas Fault, Mendocino Fault, and the Cascadia Subduction Zone.

Answer 13

Still not the answer though.
Looking or the more specific plate boundary though.

Answer 14

I'm invested in this question I'm going to figure this out let me do some more research, I'll be back lol

Answer 15

Is it a trench?

Answer 16

Example:San Andreas Fault is a transform plate boundary meaning two plates slide past each other. (North American and Pacific Plate
Cascadia Subduction Zone is a convergent plates boundary meaning two or more plates collide with each other and the continental plates always overlies on the oceanic plate. The oceanic plate of Juan de Fuca and the North American continental plate.
The Mendocino fault is a transform plate boundary. Faults are always transform. It is between the North American and Gorda plate grinding past each other.

Answer 17

Triple junction produce many geological feature that are very seismically active due to the amount of plate boundaries involved.
From divergent to convergent to transform.

I just want that one feature in that triple junction that actually produced the largest earthquake in the world. (9.6)

Answer 18

If you know whether transform, convergent, or transform plate boundary produces the largest earthquakes, then you know what features of the one you chose would have

Answer 19

I just read about the Darwin Gap and how Darwin experienced an earthquake there in 1835

Answer 20

Would it be convergent?

Answer 21

Yes, what are its features?

Answer 22

Hint: 3 different kinds of convergent
oceanic-oceanic convergence
oceanic-continental convergence
continental-continental convergence
All produce at least 1 different feature, because some have 2 features. The 2 different kinds can have the same feature also.

Answer 23

You can tell if a plate is oceanic or continental.
For example:Pacific Plate is oceanic
North American Plate is continental.

Answer 24

It's oceanic continental because of the Nazca plate which is the ocean and the South American plate is continental?

Answer 25

Yes, that is correct.
And what features are in an oceanic continental convergence zone?
Hint: Cascadia is also oceanic-continental (Juan De Fuca & North American Plate)

Answer 26

Well in North America there's the Rockies mountains where those two plates meet

Answer 27

So I'm assuming that there's mountains or volcanoes there and I read about the Peru- Chilie Trench

Answer 28

Mountains forms at continental continental collision which is C-C convergent.

Answer 29

Yes, that is right!
Peru Chile Trench can be called Nazca-South American Subduction Zone or Peru-Chile Subduction Zone.
Cascadia Subduction Zone is a filled trench so they it called Subduction zone instead.
A trench can be called a subduction zone but a subduction zone can sometimes be called a trench.

As for the other C-C convergent it produce long mountain belts: Himalayas Mountain.
For Oceanic Oceanic convergent, an example would be the Mariana Trench which is home to the world's deepest sea floor. So the features of it are island arc and trench. Another example is the Aleutian Island.

Answer 30

You live in Canada, but there is some intraplate plate boundary there. 0.0

Answer 31

Interesting I would have known this if I decided to do earth and space science as a major instead I picked chemistry

Answer 32

Intraplate boundry?

Answer 33

Seismic activity (earthquakes and volcanoes) not associated with the edge of a plate boundary.

Answer 34

The Ring of Fire is a series of volcanoes and most of them are on the edge of a plate boundary.

Answer 35

There was one in Canada not very long ago.
https://en.wikipedia.org/wiki/2010_Central_Canada_earthquake

Is that far from you in Canada?

Answer 36

Well I normally live on the west side of Ontario so it's at least a 20 hour drive to that area

Answer 37

But 1886 Charleston, SC earthquake is intraplate too and it was a 7.0.
:(

Answer 38

SC? South Carolina?

Answer 39

So is the Mississippi one that probably made the river flow the opposite direction

Answer 40

Yes, Charleston is in South Carolina.
Heard of the shooting?

Answer 41

Yes yes I did

Answer 42

Unfortunately

Answer 43

Next time I post a new question.
No more unlimited hints!

Answer 44

I'll do my research better lol
