Unreported Earthquakes off the Coast of Chile Continue

lol, ok... And actually there are stations all over New Zealand, but other than IU.SNZO, I can't ever get any of them to come up in GEE, no matter what channels I try.

Do you know if there are any sites that monitor seismic activity in the Atlantic Ocean near the Mid Atlantic region ?

You know, that's a good question because I have often wanted to monitor the Mid-Atlantic Ridge, but can't find any stations to do it. I know there have been some temporary, special study networks setup to do this, but as with most of those, the station data is only available to the institutions performing the study. But I suppose if you went on a mad rampage of searching, you might find something more on that.

Thanks for the quick response.

I have done several searches in the past that led nowhere but I never considered looking for an institute that may have done studies there.

I will carry on and if I find anything I will pass it your way.

Isn't this along the same fault line albeit up north?

Well not really, two different tectonic plates we are talking about, if one is to discuss plate tectonics at all.



That quake was on the interface of the Cocos and Caribbean Plates, whereas the Chile quakes on this thread are on the interface of the Nazca and South American Plates. So I'd say they are not on the same fault, hope that helps.

Thanks for that.....but they do 'join up' so to speak....so does what you have just said mitigate your other 'jackhammer' thread?
Just asking

When they said "large quakes," they are talking about 8+ that can do damage to, or weaken other faults at a long distance. But I realize the same principle may apply sometimes with smaller quakes and thus a smaller radius of affected areas.

To give you an example, it takes roughly a 5.8+ or so to reach faintly clear across the Pacific, say from Chile to Japan. In other words, yeah, the seismos in Chile will pick it up faintly. To actually do damage to a fault at that great a distance, it would necessarily need to be a pretty big quake, over 8+ I would think at least.

every 25 years we have a great earthquake, I think below 5 degrees tremor is very normal here even with a magnitude 6 quake, everything is working normally, but we still have in mind the Valdivia earthquake of 9.5 and 10 minutes long, so is that small earthquakes are not news but just are monitored, We are expecting a big one for the north of our country about mag +8 so we monitored all

Yeah, the Peru/Chile border area is looking like a real bad place to be right about now. If not for the potential quake to come, then for that insane inflating volcano in southwest Bolivia, close to that area as well. Far south Chile/Argentina tip could see a bigger quake too, as it's been a while.

It's first thing in the morning and I am only on my first brew, so brain not fully fired up yet!

I agree with your reply, but I would like to postulate this with you. Take a lawn mower, the sit on kind would be good. You are trundling along time after time. constant rattling and shaking...just 'vibrations', but there is a nut that has started working its way loose, say under your seat or steering wheel. You don't notice it, until one day you fire up your lawn mower and bam, you fall off your seat or your steering wheel comes off in your hand.
Now take say the constant eq's in Turkey, Christchurch, Japan. All these constant 'little' shakes on fault lines, they radiate out and slowly but surely weaken the fault line, just like a jackhammer does so slowly but surely that area of 'weakness' radiates further and further out. In the same way frakking on fault lines just radiates further and further out. Each time a eq happens the epicentre gets wakened and weakned and the tremors get bigger and bigger.....eventually all the dots join up....I think you get the picture of my analogy...everything is connected.
