Quake Watch 2010

reply to post by PuterMan

Thanks for that link again. I hope that particular add-on updates soon but right now from what I can see it isn't yet compatible with the latest Firefox version 3.6.8

Does anyone know differently or would you kindly notify us when this becomes available from the eQuake developer with Mozilla? This guy deserves our support and encouragement.

addons.mozilla.org...

Who can live without it once you start following earthquakes? I know there's more sophisticated ways of receiving earthquake data but this program totally rocks.

LOL.

What do you make of what seems to be an increase in 7.0's already this year?

Do you see it that way? Or do you consider it a 'statistical fluke?'

What should we be posting?

Just a reminder of a post some time ago

I have been looking at the amount of quakes that we post and am wondering if we should really be posting ANY quakes that are unlikely to have been felt, say under 4.0, unless there is some particular strange significance about the event.

My personal feeling on what we should be posting and how we should deal with things is as follows. You are of course completely at liberty to ignore me and tell me to get lost!

• No quakes under 4.0 need to be posted unless really significant
  
• Quakes between 4.0 and 4.9 should be posted if they are in an area of significance, for example right under a geothermal station or a nuclear site, or right on a known fault in tension. A stray 4.0 to 4.9 in an isolated area is not really of significance.
  
• 5.0 to 5.9 Yes post. It would be useful if we could indicate our feelings about why it is significant.
  
• 6.0 upwards, post of course and consider if the event warrants it's own thread. This will probably only be the case if there is significant damage or loss of life or the quake has affected a significant structure - bridge, dam, your house etc.
  

I mention creating a thread because it will happen anyway so you can bet you may well have been beaten to it!

There are no rules as such, but this has been accepted practice so this is just a gentle reminder

I thought that I pretty much covered that in these two posts

Quakes based on numbers

Quakes based on energy release

Having said that although at the time the trend of 7+ based on energy release was down even though the numbers were up, obviously we need to wait until the end of the month before I can do the calcs again.

There is no such thing as a statistical fluke when it comes to earthquakes. Despite the fact that we often say "that's normal" etc to people there is of course nothing normal about any quakes. You cannot apply statistics to Mother Nature, despite the fact that we do that all the time. She will always catch us out in the end!!

There's lies, there's damned lies and then there's earthquake statistics to 'alter' a well known phrase!

I'd call that an aftershock sequence, rather than a swarm.

(haven't looked at the numbers prior to the 6.6 on the 18th though)
I had a quick look at the 8-30 day list, I only see 1 quake prior, a 3.4 on the 15th and a 2.6 on the 11th (processed by eye, not using my computer)

Just scrolling through the 7 day list at USGS and there is a lot of red there on the 4th Aug.
4x 6's and 1x7.0

Whats up? why are they pumping up the numbers?

GEOFON only shows 3 x 6's. The rest were listed below 6.
Its usually Geofon who qualifies quakes higher.

Does this seemingly large number of Strong quake in a 24hrs period coincide with that Solar Flare phenomenon (I seen the extreme Aurora Lights on TV New)

reply to post by muzzy


I think the Solar Flare issue is on everyone's mind - who follows quakes of course and of course once again, if we knew the answer we'd be on that beach.

reply to post by PuterMan


my main quibble about the quakes posted is . . .

it would be far preferable if the MAGNITUDE

could either have a space before and after it or ideally be at the beginning of the line or the end of the line.

or else be in a table.

Yes, I was in a hurry! My excuse. I have corrected it so pleeeeese don't give me a D- teacher.

It still looks odd on Google Earth. You don't normally see that in the area. It is usually several just dotted about.

your google earth pics looks like a mountain or a top of a volcano

I would agree with you that the format as it gets pasted is not ideal. Obviously on the USGS page it is, but the only alternative to C&P is to snag the table and then it is a long haul to get the picture into ATS.

It would be great if you could have tables in a post but I don't think you can.

Edit to say it did not work

So gang, what's going on in Jackson WY?

Looks like those are maybe on a new fault line? I see fault lines there but not where the quakes are happening.

Thankyou!!! This has been my favourite thread for a long time but i've had to stop looking through it because it's really just too many posts that aren't really necessary.

A slip up like that again could lead to demotion to Sub-Superhero status

I haven't looked into it, but those names "Toms Place" and "Mammoth Lakes" sound familiar.
Wasn't there a big swarm or big quake there sometime in the last couple of years?

earthquake.usgs.gov...

Type in Lat 37.622 and Long -118.814 and say ......... 100km radius

reply to post by muzzy


Muzzy - Long Valley is another "Active" "Super Volcano" smaller that Yellowstone - by just some. Here is theHome page for Long Valley. This area is one to watch just as close as Yellowstone because the volcanic activity there is much more unstable - the gases there are way up and have been for some time - unlike Yellowstone.

Edit for late night spelling
