Me and my dad felt that one.

Was just a quick shake then went away.

47 km (29 miles) WSW (255°) from Brawley, CA

Perhaps it is System Noise

This from earthquakescanada.nrcan.gc.ca...

Signals from the seismic stations make their way to EarthquakesCanada data centres via various electronic means. Essentially, each station has its own computer system that digitizes the data from its seismometer and transmits the digital data via one or more of satellite, terrestrial microwave, UHF radio, telephone modem, or the Internet. If any of the components in the system should fail, or become degraded by atmospheric or other disturbances, there will be a loss of signal or some form of noise introduced. The computer system at the station also calibrates itself whenever it is restarted, which can can generate a strange but easily recognized transient burst

That 2nd one looks like the drum has come off its axis.

you should screenshot it and send it to them and ask what it is

Well, I would definately be happy with that answer. It could very well be seeing as how all of the other ones I usually look at seem to be having issues....it just doesn't look like your typical 'noise', or does it?

I have to say though that I went out for a bike ride and all the wildlife seems to be acting perfectly normal. I would think that if a volcano were rumbling less than 50 miles away they would be a bit jittery..

Nothing to see here, move along please!

The sound files are here in the folder Sound Files > USA & Canada

Actually, just as I first said this is 'pipecleaner' type interference. I have put three files up there in my sound folder. They are UW_MBKE_ENZ_Snippet.mp3 which is a section that demonstrates the noise. The sample rate is 2000 Hz against the file rate of 100 Hz so it is 20x as fast, It is the section from the main file UW_MBKE_ENZ_20101104-000000_2000Hz.wav that starts at 35 minutes and runs for 10 minutes. In terms of the seismo this means according to my trust calculator wot I did writ that the sound begins at 20:40 UTC.

I have also included the UW_SBES_ENZ_20101104-000000_2000Hz.wav file. The two 13 Mb files are raw data - i.e just as output from the program.

I am just about to listen to the last one now but I don't expect it to be different.

Yes it is system noise - just posted the files.

The second one looks like this as a plot and is a combination of pipecleaners, wind and earth tide, just like wot I did said!



Edit: Second pick comes from Audacity instead on my program but still shows the tide.

You are just too cool PM. Thanks!!

It almost sounds like whale songs underwater. Maybe some of that noise IS melt due to the wierd warm weather???

Either way...I can go back to my normal day.

reply to post by westcoast


The whale sound noises - i.e. the softer lower noise in the background is the mountain singing - probably water - not the right frequency for harmonic tremor. There are the odd few micro-quakes as you would expect, but the whole thing is sort of drowned by the interference.

I love listening to these!! (Actually I never do it unless someone asks a question that needs the sound to clarify)

So, being that everyone appears to have abandon my Thread, I'll ask my question here.

We have a large eruption ongoing at Merapi. The scientist are anticipating a massive eruption. Accordingly - if we have a massive eruption, we have a loss of mass within the earth - a hollow so to speak which will need to fill. We have unstable plates that are trying to re-adjust. Thinking is - if we have a massive eruption - will the displacement of material cause another the plates to shift yet further - making them even more unstable or will it be a breaking point for them to snap - hence - very large quake

Good day friends!

I see we have had another "world wide event". Wow. Can you say obtuse, thick as a brick, one sandwich short of a picnic basket?

Oh well, at least WE know what's happening. we do WE DO!

Just don't say
"pic-a-nic" basket anymore...lol Got too many Jellystone connotations to it.....

reply to post by freetree64


OK I won't. Thanks for that pic-a-nic image. BooBoo looks likes he's just felt a tremor. heheh.

reply to post by berkeleygal


Your welcome and yeah I noticed that...hehe

Thanks for all the updates and info, it really helps...

Hi Anmarie 96, I think no one is answering because it's hard to say. It does make sense all the activity will cause more though. That whole area seems to be very unstable. My thoughts and prayers are going out to all of our friends in Indonesia.

AM, thanks for mentioning your thread. Somehow I missed that one. It must have got pushed under all the November sky is falling threads. I will go read it now - it looks interesting.

Hi guys...theres this thread that just got posted now with a possible 8.7 quake......could you guys review it if you have some time to spare? would be great to find out if this one actually is really for real....

Today’s Earthquake Fact
The hypocenter of an earthquake is the location beneath the Earth's surface where the rupture of the fault begins. The epicenter of an earthquake is the location directly above the hypocenter on the surface of the Earth.

Too small for USGS list but significant none the less, perhaps related to the 4.2 and 4.7 in the Balkans (Serbia quake)
