Quake Watch 2010

Actually the newest aftershock, is the 4.9 you see at the top of this listing, the 6.1 was prior to that...

Ok, so it's building up to the new big one? Should we expect it to happen in the trench outside Peru?

So...

Of the quakes, largest in magnitude - of the top 18 - dating back to 1575 - TWELVE, or 66% have occurred in the last 100 years while FOUR, or 33% of those have occurred in the last 6 years.

Of the quakes, largest in death toll - of the top 8 - dating back to 1138 - SIX, or 75% have occurred in the last 60 years while TWO, or 33% of those have occurred in the last 6 years.

How are things not trending poorly, again?

Good points, what about population growth and the increase in the levels of reporting though?

It seems that those 2 things might even it out a bit. I say the year is still early for people to try and compare earthquake from totals of years past. Either way we started this year of shaking.

Both, fair questions.

Irrespective of the ones that have happened so far they should be getting prepared in Salt Lake City as the Wasatch Fault is due to pop one off anyway.

The pacific plate are really shaking.

I think that is a 3.9. There was a 2.1 not far from there on the 27th Feb just the other side of the fault convergence which occurs there.

Yes, the 3.8 was reviewed and now is at 3.9.

One day, this locked fault/plate line (Juan de Fuca) will snap and what happens next will not be pretty - Scientifically remarkable yes, but not pretty.

I wanted to get some opinions on this small article and statement from the San Francisco Chronicle. Their point is that when comparing data, we've only had the chance to compare full years worth and not smaller 2 month sections, like the beginning of this year 2010. Here's the quote/'snippet'

"The USGS also claims that we should expect to learn of 17 major quakes in one year and one great earthquake in any one year.

Chile was the great earthquake at 8.8 on the Richter Scale,

But while the USGS claims the earthquake frequency is not off the norm compared with years 2000 through 2009, no one has made a comparison of time frames.

In other words, was there a moment in World history where we had so many large earthquakes within such a short period of time? As of this writing, there's no documentation of such a frequency of quakes as the one the World has seen this year, with so many large quakes in a two month period."

True/False, Agree/Disagree ?

Boy, it's been a busy last 24 hrs for sure, just take a look at the World Heliplot's from LISS, talk about an active shaking world....

The 2.8 that just went off is on the same fault boundary as the other two.

This is a map of the area I have collected data for in ANSS

[atsimg]http://files.abovetopsecret.com/images/member/e6893f876007.png[/atsimg]

The red star is the last 2.8. The writing on the left is the 3.9. Now look at the writing on the right. This was the 5.9 exactly one month ago at exactly the same spot. While you are packing for the spaceport please leave a comment as to what you think about that?

Awesome/Thank You!!!
Would you mind taking a look at this being no one is home at Yellowstone. I was about to post the following when you posted.

Okay, No one is home at Yellowstone, so I will post here.. Would someone please give me their educated guess as to what is happening here a little after 4:00 & just before 17:00??? I have not seen this before that I can remember at the moment: www.iris.edu...

Almost looks like exagerated "pipe cleaners' to me, a bit odd though with the spikes during the pipe cleaner type trace.... mmm, hard to say for sure, but interesting definately.

reply to post by Anmarie96


Yes I looked at yout post on the YS thread, but I am afraid I am not into reading webicorders. They all look like squiggly lines to me. The best I can offer to try and do is to get the trace and create a sound file of it so you can hear what ever that is.

To do this I would need to know if those are local or UTC times, and if local what the offset to UTC is.

reply to post by freetree64


Pipecleaners was my immediate reaction, but from what I remember they were shorter and closer to gether BUT, as time went on the got eben shorter and closer, so is this the whole pipecleaner cycle starting up again and will it get shorter and closer?

I will get that sound file since I can remember what they sounded like.


Don't forget to look at this. I removed some stuff and made a new comment.

Link is to California seismo's, and from limited experience, when they start to look like this, we tend to have earthquake activity somewhere, I realize that's vague, but they looked like this before Haiti, and Chile too, so whether that means anything or not, I do not know, no predictions, just amatuer speculation, not packing bags yet, just looking in the closet to see if there still there, if that makes sense.

That's a cracker of a spike on this page

What caused that? Can't see anything at 18:02 - obviously - would it be the 5.2 at O'Higgins?
