That was expected after those foreshocks yesterday

Would be nice if you wouldn't tear this Thread apart. Just the links would be fine


ETA: thanks a lot, dude

We've been watching Rainier and now Helen decides to speak up

I guess 10 miles from Mount St. Helens isn't really the volcano itself

This may be an opportune moment to reiterate what we have over a period of time collectively decided are the 'rools' of the thread. They are not of course hard and fast rules, merely guidelines to keep the thread 'tidy'

1. Generally mag 6+ quakes are always reported. These may get their own thread if someone on ATS considers the earthquake warrants it, or often simply because it is 6+
   
   Any data posted from USGS, EMSC etc must be enclosed in ex tags and properly attributed in accordance with ATS rules. This applies to all the points below as well.
   
   
2. Mag 5 to 5.9 earthquakes may also be reported however we ask that this is only done where the earthquake may be significant. There are many places in the world where this may be the case and it is acknowledged that in certain circumstances even a Mag 5 quake may cause fatalities.
   
   
3. Earthquakes under Mag 5 are generally not reported as there are very few places in the world where these are significant. There are exceptions to this such as Yellowstone where a series of mag 4 quakes would indeed be significant. This also applies to other volcanic areas.
   
   If you feel that a particular Mag 4 is of significance then please do post it. All we ask is that you offer some reason as to why this may be of significance.
   
   
4. Quakes related to fracking. These will probably be under mag 4. If you think a quake is related to fracking then post it and please try to pin-point the wells nearby that may give rise to this.
   

Nothing is set in stone. These are just quidelines.

Close enough however to cause a big signature on the MSH seismos. B202.PB..EHZ.2012.025

I don't think 10 miles is too far. There have been some other bumps recently according to the seismograms.

ETA: Here have some more
B204.PB..EHZ.2012.025
B201.PB..EHZ.2012.025 (The closest I think)

reply to post by PuterMan


Sorry Puterman, I didn't realise it wasn't actually the volcano til after I posted. I saw Mount Saint Helen's and went into alert mode. I'll be more thorough in the future.

reply to post by megabogie


I was not complaining I was agreeing with you. 10 miles (9.96 actually) is close enough to bear looking at.

It is a volcanic area and therefore is relevant.




It even showed well on Rainier. RCS.UW..EHZ.2012.025 and STAR.UW..EHZ.2012.025

reply to post by PuterMan


Again sorry..I was responding to your guidelines for posting...didn't see your post on St Helens till afterwards. Need more coffee.

reply to post by herenow


We woke up to this, in my area, but it says 4.9 here, and was heard in whole North, and in Emilia is the epicenter.

I ask, could it be a foreshock?

reply to post by Zagari


I believe it was 4.9 ML which may be the reason for the difference as USGS is quoting Mw. They all vary. EMSC has it at 4.9 Mw

Foreshock? No. Extremely unlikely as this quake is at the top of the high end of quakes for the area over the past 40 years. Mag 5.4 is the highest.

Good thread and guidelines

I wanted to mention this with regards to fracking and drilling. I'll cut down the fat of this post as much as I can. Here's the YouTube link to the President's address.


NA Craton. With EQ3D, here's the past week, from 1+ mag. Not all are near sites.

Not completely unheqrd of for a quake in this area (around a half dozen or so since 1990, if I am reading the historic seismicity map correctly), but interesting nonetheless:

I was expecting that to be further south! Yea, cool. One has to wonder where they got the historical seismicity from. Obviously not the PDE catalogue.

Are the numbers of mag 5 quakes in the NZ region on the increase?
ABSOLUTELY

unfortunately a lot of LISS stations are blank right now incl SNZO earthquake.usgs.gov...

Muzzy are the usual averages for NZ still being distorted by our activity here in Canterbury?

reply to post by PuterMan



see the LISS is blank for all day to 16:35

I got a screenshot of LISS SNZO showing the 5.7 early when I got up in the middle of the night, will post it on my SNZO blog page later.

Good signal at IRIS ODZ
