Quake Watch 2011

reply to post by Roald


Please don't think I was trying to pull you up on that. As I said earlier the difference in pressures is what interests me and is something I have to get round to investigating in depth. I am beginning to think that in addition to anything else that we should collect the barometric pressure and preceding 24 to 48 hours curve might be significant. I have just about started on European and Atlantic/Arctic charts now and will add the others shortly but these are charts and I need to source ASCII data that can be got at to download automatically. I have not looked very hard yet but I will.

I also ignored temperature and those were calculated a 5 deg C. When you throw in Earth tides and other gravitational effects I wonder just how much influence these do all have.

Just forgot to mention Folks that I put muzzy's new thread in my signature so you can get at it anything you see a post by me. That should not be a problem as I make on or two.

I could not fit in the Title "Hurricane/Cyclone/Typhoon/Tropical Storm/Big Shower/Breezy Day Watch 2011" so I called it Storm Watch 2011.

Since I cannot get at the SHZ channels as they are are not publicly available i thought I would take a look at what is available.

Right next to you on the Mt Constitution seismo that quake shows well: MCW.UW..EHZ.2011.016 (These are good for 8 days by the way)

South of you on the Rockport seismo: RPW.UW..EHZ.2011.016

South of you on the Jim Creek seismo: JCW.UW..EHZ.2011.016

All I can say, since the data is not publicly available is the there was no difference in channel sensitivities in 1994. Whether that has ANY relevance now I do not know.

Obviously the poles and zeros are of no interest from back then. Poles and Zeros? Some reading can be found on this site and when you have uncrossed your eyeballs and placed the contents of your cranium roughly back where they came from, should you still have an interest in poles and zeros and have been convinced that they do not refer to impoverished foreign nationals, then you might find the book below of interest if you are interested in digital filtering in relation to seismic waves (and have $32 to spare - which I don't) then you could take a look at this book on Amazon. Of Poles and Zeros: Fundamentals of Digital Seismology (Modern Approaches in Geophysics)

Digital signal processing has become an integral part of observational seismology. Seismic waveforms and the parameters commonly extracted from them are strongly influenced by the effects of numerous filters, both within the earth and within the recording system. With the advent of numerous software tools for the processing of digital seismograms, seismologists have unprecedented power in extracting information from seismic records. These tools are often based on sophisticated theoretical aspects of digital signal processing which, to be used properly, need to be understood. This book is aimed at observational seismologists and students in geophysics trying to obtain a basic understanding of those aspects of digital signal processing that are relevant to the interpretation of seismograms. It covers the basic theory of linear systems, the design and analysis of simple digital filters, the effect of sampling and A/D conversion, the calculation of 'true ground motion', and the effects of seismic recording systems on parameters extracted from digital seismograms. It contains numerous examples and exercises together with their solutions.

Ah exercises!

For those disinclined to shell out $32 to have their brains scrambled you will be pleased to know you can have it done free of charge.

I notice the Japan region seems to be getting a lot of activity today..

Thanks for that

The topic took off with lots of replies in the first hour, but has died away now.
We need an ATS reporter from New Caledonia on here

venez en Nouvelle-Calédonie

Okay, just reading what you wrote there and thinking about it, gave me a bit of a headache!!!

Thanks for the links and info though!

I am ONE ATS year old today!!!!

If I remember correctly, my very first post was in the Quake Watch 2010 thread.

I love you guys!

Here's to another great year at ATS!

Thank you for being my friends :-)

Happy Birthday!!! I think that was the first place I posted also. It is what brought me to ATS, and what keeps me here!!!

KMZ file of that lot in my drop box. I will leave it there for a few weeks then it will be transferred to 4shared.

A barren land indeed. Except for that river.

Been pretty quiet here in NZ for the last few days (since that Mag 5.5 up on East Cape Ridge).

Bit of a swarm going on at Lake Rotomahana, near Mt. Tarawera volcano (Pink and White Terraces/ Waimangu fame) this up to mid day NZDT yesterday, may be more on new download today

and another possibly volcanic related swarm around Warea near Mt. Taranaki (Egmont) volcano been going on for a few days

will be interesting to see what happens quake wise over the next 24 hrs on the West Coast of both islands as ex-Tropical Cyclones Vania and Zelia pass through, expecting 4" of rain here where I am, theres a Low coming up from the SW to meet them, barometer readings are down to 988/990



Its warm and humid right now, Gales expected later today 130km/hr+

reply to post by PuterMan



lol PM your right a lot of us did join in jan my self as well.

reply to post by muzzy

barometer readings are down to 988/990

So when is that going to turn into a storm? 980 off Iceland today.

I guess once it gets down to around the 960s it may turn into a bit of a breeze?

Took a quick look on Google Earth weather after reading your post. So... what do you make of all the lines/clouds?

I gather that is Google Earth 6 (Beta) I was wondering why I had never heard of it.

I am just loading it now, but those don't look right for the weather they are supposed to be having. They look like chem trails ny other half says

Unusual satellite image - have never seen line such as this. A glitch perhaps? Will check it out on Stormpulse.


BTW the house just shook for few seconds here in N. Indiana - felt like a small quake. Anything on the graphs?

reply to post by this_is_who_we_are


Don't see that on mine.

Glitch perhaps as I can see some others that look like the picture you showed.

@CD - nothing I can see at present.
