Is there some significance to this? Do you have some observations to make about these quakes which in essence are all just aftershocks of the 8.8 last year?

Just wondering.

"aftershocks of the 8.8 last year?"

Just wondering.

I wouldn't call it aftershock.

Last was : Feb. 27, 2010
This one : Feb 11, 2011
Almost same date, one year difference.

Epicenter : 36 degrees south latitude and 73 degrees west longitude
(almost exactly where the Feb. 27, 2010 earthquake was centered).

There is still no mention on the RSOE site:

If they don't mention it in the next hour, that site may be considered not reliable from now.

They mention the 5.3 but nothing about the 6.8.

Everything is connected.

I got family down there right now, they are saying it reminded them a lot about the historical quake from the 60's.
While being on phone I heard a lot of canines in distress in the background. I am hoping they will arrive back alive.

Prolly one of the worst places they could be right now.
They need to pack it in IMO..

I hope your family are ok brother. Let us know, if the people overthere are planning to move to a higher place for tonight or will they stay at home.

I've seen a short clip in an spanish channel (I think 47 telemundo), lots of people outside, all scared.

Thank you Trueman

That's exactly why I would call it an aftershock - same location etc etc. Activity has NOT returned to normal in the area since their big 8+ quake last year, which means these are aftershocks... aftershocks can continue for months/years.. after our 7.1 in September here in NZ we are still getting aftershocks and it wasn't nearly so big as their mainshock.

4 now

another 6.3!!!

reply to post by heineken


Worrying news to me

The first large one was approx 60 seconds long, the latest one of 6.3 was only 10 seconds

the Sun released only 2 cme's this February, doesnt seem though powerful enough or fast enough to have influence on the latest 4 Chilean quakes

So, that means we need an earthquake higher than the one on Feb 27, 2010 to stop talking about aftershocks. Meantime, we can see land shaking for "aftershocks" for let say....forever?

Please, lets focus in Chile and don't get lost between definitions....PLEASE.

Well, there isn't anything to really focus on here. According to most of the media groups, there has been no major injuries and no deaths, which is fantastic news.

"There have been no reports of major damage or injuries in the wake of a 6.8-magnitude earthquake in Chile, according to the country's leader."

www.cnn.com...

And in regards to MoorfNZ and Puterman, they are obviously correct in that this is simply an aftershock. Even the President of Chile is calling it an aftershock, and it meets the definition of an aftershock according to the USGS:

"President Sebastián Piñera told TV Chile that the quake was felt from Valparaíso, north of Santiago, to the lake region in the south. He also said it was probably an aftershock of a massive and deadly temblor that rocked the region in February 2010. " www.cnn.com...

and "Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 rupture lengths distance from the mainshock. Aftershocks can continue over a period of weeks, months, or years. In general, the larger the mainshock, the larger and more numerous the aftershocks, and the longer they will continue." according to the USGS, earthquake.usgs.gov...

If the USGS and the President of Chile think it is an aftershock, and there is no major damage, then what is there to focus on?

Don't get upset when someone corrects you, It helps to learn the difference as to not get panicky. The Quake Watch thread by Puterman can teach alot. www.abovetopsecret.com...
