And now a 6.0 on land. Does not appear to be too many buildings close to it.

Oops apologies coffeesniffer and Roald, did not spot your posts.

5.9 just came in as I was editing

What is with all these large aftershocks? I do not follow the world of earthquakes closely, but I do not recall ever seeing this many and of this large of magnitudes. What do the experts think of this, anyone?

A bit scary if you ask me.
There are houses in the area because Chanco is almost right over the spot.

Edited to say sorry to PuterMan. Did not grasp your sentence in my hurry.

The activity of shocks and the Magnitude since "The Big One" is a tad unsettling!

NotAgain has started a thread about the wobble caused by the Quake and its effects on Chilean Astronomers, the stars appear to wobble as the earth "trembles" from the event even 24 hours later!TREMBLING EARTH, WOBBLY STARS

PuterMan has added lots of good info, and expertise on the threads and some of the most recent Graphs and data he shows Here in Quakewatch, abundantly shows that!

So it’s on topic and I will put the PIC here, really brings home how much energy was in that event.

There is a much better quality HerePic

Just wishing another large event does not happen here as the Magnitudes are quite high and frequent.

Kind Regards

Sorry if this sounds silly, but how can they be stars, in the daytime??
The sky looks to bright to be seeing stars.

Yes I said there not too many, not that there were none. Chanco is relatively small.

Note that the 5.9 off shore and the 6.0 on land were just 6 hundredths of a seconds apart. Double whammy or what.

I am just going to see if this has affected the overall power trend.

Edit: No noticeable change in the power trend so I won't post another graph.

Edit: Apology not necessary - I duplicated one of yours so we are square!!

If it was dusk then you could see the stars, and the long exposure required not only causes the blurring, but also brightens up that background so it does appear there are stars in the daytime.

Just had a look at the larger file. The EXIF information says the exposure length was 88 seconds.

Oh, thank you, learn something new everyday

Now where did the Magnitude 6.0 at MAULE go?

Gone from the map.

First off HAPPY BIRTHDAY TO THE USGS:
The United States Geological Survey was established on March 3, 1879, just a few hours before the mandatory close of the final session of the 45th Congress, when President Rutherford B. Hayes signed the bill appropriating money for sundry civil expenses of the Federal Government for the fiscal year beginning July 1, 1879.

IMO The Chile earthquake was set off by the Japan earthquake. Stress is high around the pacific plate. The earthquakes that are now happening are aftershocks of the main event as the earth settles - and hopefully will cease after some time instead of triggering another large quake, which IMO is entirely possible if not most likely. not all Large earthquakes that occur have fore shocks, it all depends on locations, stress, strain, jolt and volcanism.


Sorry for the late post - was on page 14 - interupted by phone calls and by the time I hit post - well, the rest is obvious

I knew it was entirely toooooo quiet yesterday. The earth is starting to react. New Madrid, San Francisco, Long Valley. No word from Alaska yet - IMO this is a bad situation.

The answer to that is that it was deleted as it is now residing at the top of my deleted quakes list.

One of these in the list of quakes deleted from Chile is old but 2 are from this current episode.

Date/Time UTC,Latitude,Longitude,Magnitude,No Of Rept Stns,Depth(Km),Location
03/03/2010 17:44:34,-35.7500,-72.5300,6.00,7,33.00,Maule. Chile
27/02/2010 17:33:50,-36.0675,-72.0852,4.90,19,35.00,Maule. Chile
10/06/2009 23:13:24,-41.6520,-84.0550,6.10,10,20.00,West Chile Rise

Actually perhaps a bit of explanation as to how i get that list is needed.

My QuakeData program automatically downloads from USGS once a day (and more often if I wish). The file I download is the 7 day file. The program looks at each quake in the file based on the EQ identifier. If it has been revised (i.e. the parameters are different to the original, it moves the old one to the revisions table and replaces it with the new data.

IDs not found are added and then it looks at all the IDs for the datafile compared to the incoming (for the date spread of the incoming) and if it does not find one it assumes it to have been deleted and it is moved to the deleted quakes table.

Nothing ever actually gets deleted and thus I can tell what they have been up to, including the 50%+ of deletions from Yellowstone Park against the average of 4 to 6 % for everywhere else that I noted in the Yellowstone thread quite some time ago.

Addendum: I think the Bio Bio one at the same time got upgraded. I thought it was strange that they were only 6 hundredths of a second apart.
Latest first in this revisions list.

Hi, I know Anmarie96 has answered you but I thought I would put in my 2 pence worth, or cents worth for the Mercans.

This is only very rough but from 1st Jan 2009 to the day before the big one in Chile there were 95 quakes ranging from 3.5 to 6.5 the average being around 5.0 magnitude or just under. If I separate just the area currently affected there were 40 quakes.

Only about 18Km from a heavily inhabited area. Hope there are not casualties.

Update: but right under a small inhabited area with several small areas around it in the mountains.

[edit on 3/3/2010 by PuterMan]

OK what are they playing at? This quake is lepping about all over the place. It is not on top of an inhabited area now.

[edit on 3/3/2010 by PuterMan]

9.7 miles from a primary school. What time is there? Anyone know?
I got it 08:53 in the morning at this edit. Darn - fingers crossed.

Just got the Tsunami bulletin for it

No threat is current

"Therefore I will shake the heavens, and the earth shall remove out of her place, in the wrath of the LORD of hosts, and in the day of his fierce anger."

Isaiah 13:13

This is why people are saying we are in the "last days".

Figured it was a timely reference. I'm not preaching or anything.
