Quake Watch 2011

So I am trying to figure out what I am seeing on some seismos that are near me. Anyone want a poke at it?

Go HERE at check out Marblemount.

You can go HERE and look at various stations around the state. It is a really cool site.

The corresponding ones are MRBL, RPW

Then you just gotta check out Glacier Peak,because it is going crazy again:GPW

It is a sombre reminder that under the wrong circumstances even a 5.4 earthquake can be lethal. I saw that quake in the list when I looked this morning and passed over it thinking it was too small to be serious.

All to do with sunspot activity ramping up towards the solar max around July 2013 which will however be the lowest solar max in 200 years if things keep going as they are.

Maybe instead we could be looking at frequency of over 6 mag with solar activity? The flares may not correlate with large mag quakes occuring, but maybe the frequency of them occurring...There have been a few in the last couple of days.

Just checking out EMSC data, and I did a criteria search for 6+ for the last 12 months. While 3 x mag 6+ in one day occurred on 9 days of the last year, only one day had 4 x 6+ mag (Oct 25) and only one day had 5 x 6+ mag....yesterday....March 9.
Apparently solar activity was dull on the 25th October (link) so now you can ignore my original first sentence about frequency. Let's just rule out solar activity full stop.

I didn't. Saw it come in on PS.PSI in GEE, and man, that was a beast. Looked to be bigger than that. PSI is 1500 miles away and that thing was a huge signature, long decay, more like 6.3 to 6.5. Distance can spread them out though, making the decay look bigger than the local version on a closer station. Learning that the hard way, and Arkansas is teaching that lesson quite loud and clear. What looks like a strong spike at WHAR turns out to be much longer decay 40 miles away on another station. I am still puzzled by the huge difference that close. Something's still weird in Arkansas.

China/AOL

Looks like China got a 5.8. I haven't imbedded any videos yet, but they are on the link.

An earthquake struck China's southwest region today, destroying buildings and causing at least 22 deaths.

This is really bad for a 5.8, must have had the epicenter right there.
Will check out the news for this one.

I have just found this. It looks interesting and I shall be exploring it more.

Ok... this is making me think "WTF" and I need help understanding. I have been watching quakes from the USGS for too many years to count now. It's a possibility that I have not paid attention if it has happened before. However, until today, I have NEVER seen an earthquake at a depth of 315 miles, like the 6.2 in the Bali Sea today.

Is this something unheard of??? Or at the very least, unusual??? Is this cause for more concern elsewhere on the planet???

Help a girl out here. Please.

Ok fellow quake watchers, as you know I'm pretty level headed and report quakes daily on a FB site and I sit and watch the world wobble via various websites and progs each day.

I haven't subscribed to the "there are more big quakes" theory before.

Maybe because I've been through the 7.1 and 6.3 here in NZ I'm feeling just a wee bit more anxious than most, but, I'm finding it really had to tell others on my site that the amount of large events in the last few days are "normal".

Someone please give me a virtual slap.. or some data to make me feel better.

I've lived by the Alpine Fault for 7 yrs now (we're in the foothills, inland from Chch). Always known it was there, always known its potential. But, we've been complacent and the 7.1 kicked our arses. Now those beautiful Alps, while still beautiful, fill me with fear. Each night I go to bed wondering if tonight will be the night, I stare at the vaulted ceiling and try to work out if the beam will fall on my head or on my legs.

I've tried to be brave since Sept. I'm not finding it as easy to be brave these days.

Around that area of they do get very deep, I have seen them deeper (Mindanao way I believe) ... I see if I can find some examples for you.

From USGS: The deepest earthquakes typically occur at plate boundaries where the Earth”s crust is being subducted into the Earth’s mantle. These occur as deep as 750 km (400 miles) below the surface.

Thank you for that!

Not sure how comforting the subduction part of it is... LOL ... but it gives me a broader understanding. Thanks again!

Just a quick thought - maybe move your bed out from under the beam Here is the list of larger quakes from the past week. If you take out Japan and the aftershocks, it appears normal. Just remember, we went through a relatively quiet period for a bit there - so it may appear that we are having more - but we are not - i think - Maybe if Puterman isn't to busy he can give you a graph

Puterman - you have been quiet the past few days - you OK?

I can't, there's a beam every 6ft across the room... and the walls are breeze-blocks filled with concrete and are tall (at least 18ft high) with vaulted ceiling..

No way we can move or sell now, either.

My anxiety must be causing paranoia and irrationality. Maybe we should re-enact that scene from Airplane where they line up to take turns to slap the hysterical passenger!!!

Wow, I see what you mean - any ideas on what's going on there?

Thanks for the link also.
