and it looks like they just got up in Alaska and added a bunch of new quakes and downgraded some. That Alaska map was completely yellow yesterday and this morning.

If you need to knock down an "OMG the numbers are increasing" post then in addition to my earthquake analysis that is in my signature I have sort of replicated a reply to a post on ATS. You are welcome to use it as ammunition.

Do earthquake numbers matter?

Regarding Cedar flats seismo at St Helens, The wind there now must be gale force as the seismos are going wild today. June Lake is about the same as 12 hours ago, and the Crater seismo is picking up. Snow storm perhaps....Westcoast??

Does not look like it from Seattle.

Time and Date.com

It was windy up here last night (I'm 30 miles south of Seattle). Not sure how far back the readings go date wise. As of right now it's not real windy..

reply to post by zenius


Ha! Finally found Mt St Helens weather forcast. Blustery with gale force gusts, north westerlies. source

reply to post by zenius


Nice one.

Well done. That is definitely a keeper.

Well, I don't live on Mount Saint Helens...but I can tell you right now in Skagit County, about 100 miles to the North it is sunny out with mostly blue skies. I am about to go for a walk because I HAVE to get out and get my exercise in while I can.

I was just hoping over here to post about the 5.2 quake that just occured off the shore of Oregon. I have been talking about Oregons off-shore quake, the 3.2 in the San Juans this morning and the very small, multiple quake activity in this region this recently.

While I can't say if that is wind....I can say that it certainly woulnd't surprise me to see the siesmos getting a bit wacked right now!

Edit to add: I questioned earlier today on my other thread if the oregon quake last night and the san juan quake this morning might be fore-shocks. Hopefully this 5.2 will now release enough energy to quiet things down, rather than pull the trigger.

Can some of you go to this thread and give your expert opinions on it? I would love to hear what you all think about this.

The world is moving heavily again today:

hisz.rsoe.hu...

earthquake.usgs.gov...

It feels like they get more and stonger...

I would appreciate it if the local experts in this great thread would be so kind as to answer a question for me, or point me in the general direction to find this out. Does the depth of an EQ have an effect on the aftershocks? For example, would the 6.5 in the Philippines today be less prone to having an aftershock since it was 528.4 km deep?

The 6.5 was posted here but not this one

Very often the very deep earthquakes do not have any aftershocks. Just occasionally there will be a series of deep large quakes but these could probably be more equated to a swarm than after shocks. Moro gulf is one such example,

reply to post by PuterMan


It makes sense that the deeper ones have less.

Thank you very much!

reply to post by berkeleygal

I missed that one yesterday when I looked, did they add it later

since the 2 Celebes Sea deep quakes there have been these deep quakes also (in ascending order)

Are you indicating a connection between these?

They are 4000 miles apart so what would be the connection, or are you just observing the they are deep?
