I'm very sorry to hear that and I hope things get much better soon. I understand that you are in Santiago, Chile. It must be a terrible feeling when the ground is shaking so much and so often.

Stay safe!

Blessings and wishing you strength and safety at this difficult time!

Mike

from the 8.8 im wobbling

Roald, I do not disagree with anything that you have posted other than "the next big ones" I think a better term would be "one of the next big ones" omho.

I'm still quite clumsy with my posting. I meant the next "BIG" one (M8+) in the Peru-Chile Trench.
Might not make my post better though.

Putterman. Do we? No, I just had to let it out when I saw referral to the experts, "seismologists/geologists".

[edit on 11/3/2010 by Roald]

2 earthquakes' magnitudes have been downgraded.

the 1st from 7.2 to 6.9

the 2nd from 6.9 to 6.7

after those, a 6, a 5.4 and a 5 occurred.

My point was not that the "experts" are always right but that I feel your analysis of small quakes letting off tension is wrong. While experts may not be right all the time they are deemed experts because they know more then the average bear. Not a dig on you or anything, so please don't take it that way.

Curious though, you are pretty well spoken on the subject. Do you work in the field or what is your background?

I would like to get other opinions here. We just had Chile let off some major steam so to speak and other than that area and the small usual quakes up the North American Sea Board, which is few - The rest of the Earth is still Very, Very Yellow. IMO there should be some reaction somewhere. Am I missing something??? This is all toooo odd. IMO something is very amiss here. It is not good.

To those of you in Chile, my prayers to you!

Also, is anyone else having difficulty pulling up seismo's from PBO?

I know, and just the other day, we were saying it was too quiet, remember, now it's too busy in Chile, and quiet everywhere else... "watching"

Not quiet here though... LISS 24 hr Heliplots, are busy today...what a mess, if only I could interpet their meaning...

Those are the seismo's picking up the chili quakes - look closely. The events were large enough to black out the following hours. - At least I hope that is what that is. Yikes

Yep, your right, and upon closer inspection I see that, but go back a couple pages in this thread and view the 24 hr heliplots I posted, big difference....

Let's hope you are right that it let off some major steam instead of building up to let off even more.

Cool little map or diagram of the area in question with plate tectonics listed...

Yikes, those recorders went bonkers!

Yeah where the hell are the sandwich islands? That seems to be an unusual location for a quake.

It's located on a convergent plate boundary between Scotia Plate and the South American plate. Not far from the Antarctic Circle, and believe me, quakes are not that uncommon in that area. I think it is around 9 volcanoes in that zone.

Don't worry. I did not take it as an attack on me. I promise.

Let's just say that I'm a guy with hand-lens, compass, pen-knife, handcuffs etc. tied round neck with string and consumes tonsil-killing chili for dinner every night of the week, and warms it up in a can on the drill rig engine block and whose shorts expose way more leg than you ever wanted to see.

Now you try to figure out the rest.
