Quake Watch 2010

I'm still here :-) but it has been entirely to quiet on all fronts. It appears everything went on the back burner for a sinister simmer for the past week or so - quiet frightening if you ask me. Something has got to give before to long and if we look at the quiet times and what follows - well - it's been quiet for awhile now.

Good to see you all back

I think its just as interesting to watch the smaller quakes as the big ones, sort of get a feel for the background seismology of the various parts of the world.

Heres one I missed the other day, quite big for Australia mainland

It does. While this all started with the Baja 7.2 I do wonder whether this ongoing activity along the fault line is a new event building as a result of the 7.2, but further north around the Long Valley area.

Just noticed a thread going about this: www.abovetopsecret.com... [edit on 7-6-2010 by MoorfNZ]

That is precisely my thought. It seems to me that we have moved beyond the point of calling these quakes 'after shocks'...I mean, how much time and how many miles have to seperate them from that event to catagorize this massive swarm as it's own event?

You see the clear pattern of energy traveling up the fault line, the Mammoth lake swarm that is still on-going, the recent swarm at Mt Hood, and we continue to have a higher than usuall quake level here in the pacific NW:

[edit on 8-6-2010 by westcoast]

Aftershocks can go on for months, sometimes years, depending on the original quake size, depth, location etc, so it's not surprising we're still seeing increased activity in the CA area - but that doesn't mean, as I said above, that the original quake and aftershocks haven't triggered something else.

As I understand it the 'background' seismic activity has to return to 'normal' levels before they consider the event to be over so I would say that Baja and Chile are not over yet.

reply to post by muzzy


I agree that the smaller quakes are just as interesting - in fact probably more so as they give a more detailed background as to what might be going on. If for example you have an area which is continuously giving off small quakes then you may be able to say that stress is being relieved, or if it is volcano associated that magma is on the move or a chamber is filling.

On the other hand if an area just produces the odd 4+ or 5+ every now and again you have no idea as to what is happening.

Our problems, as I see it, are these:

• For many areas we only have access to larger quakes, maybe 4.5 upwards.
  
• Within the States generally 'easy' access to downloadable current data is limited to 1+ quakes.
  
• Smaller quakes in many areas of the world we cannot access as the information just is not available on line.
  

Does any of this matter?

Well actually no it does not since we don't - even collectively - have the knowledge to fully interpret these things even if we did have full access to the data. Basically there is nothing we can do about it.

Is this frustrating?

Yup, frustrating as hell! We just have to live with it!

So do we need to keep on watching these quakes?

Hell YES! It is fascinating and, depending on your point of view, you can frighten your self to death with 'OMG it's all about to go off', or calm yourself with 'Well this looks like normal activity - nothing to worry about'.

Personally I prefer the latter.

I believe these Oaxaca quakes are part of a little shimmy by the plate they are near.

Not too deep the last two, but there seems to be some movement all around the plate boundaries.

I've only been checking what's been reported on the weatherchannel.com recently. New Madrid has been having small tremors almost every day for a week.

Is this activity on the New Madrid fault higher than normal? I have no reference to back this up, but I have always thought it to be a scientific fact that large oil spills(like the one in the Gulf) can displace enough mass to trigger earthquakes.

Any opinions or information would be welcome. I am about as far from an expert on the subject as you can get.

Here's another around New Madrid-

earthquake.usgs.gov...

They've been from 2.0 to 3.1 for over a week now almost every day. I've never seen this much activity before. Hearing that oil displacement might be a trigger is disquieting.

Thanks for the New Madrid activity - was not aware of this. Didn't show on RSOE site map.
