Quake Watch 2011

reply to post by PuterMan


Hey PuterMan thank you for your reply

I'm glad you think the idea would be an interesting exercise, albeit a very long winded one.

If I knew what to do and how to use the software involved, I would try giving it a go myself. But to be honest I wouldn't know where to start.

With my App, I do have the actual alert/notification filters set to 4+. But the daily list filters (which I have to manually check) is set to 1+. Which i'm happy to skim through at the moment and check out the maps, as it familiarises me with the areas and how often they occur. Modern Technology, who'd of thunk it?

English is my third language.
i was refering to 'building of sentences, phrases and the correct use of words, or what you call it
for the spelling i can always google

right now i dont have to much time to do much analyse, cause i am repairing some parts of the house, but while doing, my head is always wondering and thinking, thinking,...

Well all I can say to that is that you are better at it than many who supposedly have English as their first language (after txtspk of course )

I am also a little busy at present, but I will help if I can.

Actually if you only want 6+ then it is not too big. I may have a go at it tomorrow.

which is code for line 2

Edit: Just looked at it and there is no clockwise movement. They are all over the place round Japan then one in Myanmar down to Fiji and back up to Japan. That is for 6+

I guess 5s are going to be about the same.

Not sure if you thought about this,but how about "creating" another way of measuring the Strenght of Earthquakes?

The last NZ Quake showed that smaller,shallower (sp?) Quakes can do more Damage than Bigger,deeper ones.

Something like Magnitude : Depth = Actual Damage/Energy Release


You know what i mean?

Muzzy might be yer man for this one.

I guess what you might be talking about would be the peak ground acceleration since that is affected by depth and magnitude.

It is something I need to get into a bit more than just the pure energy of the quake.

I did collect the Peak Ground Velocity for a few weeks last month for quakes in the Chrstchucrh area,but it all depends on which stations get the data, as not all stations record the PGV for every quake even within the Christchurch area.
Therefore the closest station always show the highest PGV ready.
Nothing there I'm afraid .
It all comes down to depth and magnitude, and proxiity to built up areas.

So I thought, wouldn't it be cool if someone could make a Gif that would show Quakes starting from the Big One in Japan, or the day before, up until now, happening specifically around the Ring of Fire. To see if there is a clockwise pattern or domino effect happening.

This is way beyond my capabilities and is probably a huge amount of work. So just throwing the idea out there.

edit on 2-4-2011 by skitzspiricy because: (no reason given)

I did something like that a few years ago, like you say its a lot of work. The way I did it was each quake icon on the map was an image, and fed into a gif programe to build a progressive a sequence.
When I did that I was doing it in reverse, going from a big quake, backwards to the last big quake, to see if there was any pattern
There was no pattern, everything is random.

Anything with over 10 images is getting to be a slow process.
I have since deleted the gifs from my computer.

There are other ways to do it using KML in Google earth, but of course it only works if you have Google Earth.

Ideally as each icon (quake) shows it should fade away to 50% opacity and stay there when the next icon quake comes on, so that you can still see the build up.

I'd have another go at it , but its only a hobby and I can't even keep up with NZ quakes right now, averaging 40 per day.

Like "The Deeper the Quake,the less Energy is released at the Surface" this.

But you gave me another Idea for something which should be monitored more closely. The "Experts" tell us that Mountains took Millions or Billions of Years to form,or that the Plates only move a few MM/CM per Year.

I call BS on that,because Japan moved a few fricking Meters in just this one Quake (might be because of the Location,but...) What about the Big Quake in Chile? Or the Sumatra one?

This should be monitored,because our Planet could change quicker then we think/know.

Thank you both

I did actually just find the EMSC interactive earthquake map, which is satisfying my curiosity a great deal.

EMSC Interactive Earthquake Map

What I did notice when playing around with the map, was that before and after the Big Japan Quake, most of the activity seems to be concentrated to the Western side of the Ring of Fire, whilst the Eastern side seems to be relatively quiet (more so than usual?). But the Eastern side seems to have picked up again over the past few days. Nothing huge Mag wise I know, but it has seemed quiet, atleast in my eyes, but I am quite a novice.

So, is that usually what happens, to see a kind of ping pong effect across the Pacific? Say for example the 8.8 in Chile. Did the activity on the Western side of the Ring of Fire calm down just before, during and after Chiles big shaker and then pick up again?

Look at this reading from Waverly, TN

Hi Susan. That is quite sensitive - 200 mV

Take a look at it on this one - WVT.IU.10.BHZ.2011.092

Not nearly so 'scary'. Nothing to worry about there, it is magnifying the microseisms greatly.

reply to post by PuterMan


I like yours better. Thank you, that was a little spooky looking.

reply to post by PuterMan


Yep, just pulled up IU.WVT BHZ in GEE, and it is showing normal background levels, nothing strange. IU.WVT? Yes, IU.WVT. That is supposed to be NM.WVT, as part of the New Madrid network, but sometimes it doesn't work that way, when parent networks take over subnetworks, or particular stations on subnetworks. In fact, another station comes up in GEE called US.WVT, which never has any data.

And to be honest, I am glad, because the NM network has been having terrible problems for a very long time. I have expressed this concern before, especially at such a critical place on the New Madrid.

Good Map, I've seen it before but didn't bother to play around with the settings.
You can change the colours of the squares I have my own preferences for magnitude colours

It is in 6,500m of water so probably not going to have too much effect.

Big enough to trigger a tsunami i wonder? That area sure doesnt need another one.
