3 quakes in Chile wave file (1.7MB) lasts about 20 seconds and is the waveforms as 'heard' at WY:YHB::EHZ. It is about 100 times speed and I had to change the pitch to get to hear anything but it does sort of illustrates the difference in magnitudes.

The first quake was twice as strong as the second, which was 11 times stronger than the third. The first was 22 times greater than the third. Isn't maths wonderful!

5.8 in Chile to add to the list above.

ssn.dgf.uchile.cl...

maybe is more accurate

reply to post by Patto


Pichilemu seems to be getting a pasting.

Just be aware on that list that the method of measuring the magnitudes changes between quakes. NEIC are in MMS and I think the rest are Richter.

Sorry should have said that the change may not actually make a difference.

Good Morning Quake watchers!

Did ya'll kick start O'Higgins or what????

sheesh!

reply to post by PuterMan


Excellent wavefile, and that was something, very good, and thanks... Also, this is for those who are not aware.....

An aftershock is a smaller earthquake that occurs after a previous large earthquake in the same area (the main shock). If an aftershock is larger than the main shock, the aftershock is redesignated as the main shock and the original main shock is redesignated as a foreshock. Aftershocks are smaller earthquakes formed as the crust around the displaced fault plane adjusts to the effects of the main shock

Apparently there has been an earthquake in seal rocks on the central NSW coast here in Australia, the news is saying it was a 3.53, could not see anything on USGS but they said people were woken with the windows rattling and one person said it 'sounded like bombs going off'

Here's all i can find on it Seal Rocks EQ

reply to post by bkaust


I doubt if it will turn up on USGS. I think they only look at 4.0+ that far from 'home'

You might get some data on the NZ service. The link is in the thread.

Tonga was separate event but could have caused the NSW one - half expecting one here in New Zealand now but GeoNet NZ is slow to report....

reply to post by MoorfNZ


Understood, I figured it was shallow enough to be felt in NSW, and it was the only USGS showing up when ya asked, sorry bout that. I knew it wasn't the earlier Indonesian event, unless we missed something that is....cheers

How come I can only see one of these in the USGS data?

Edit: I have double checked and still cannot see any of these other than the 3.4. Can anyone else find them?
Looking round their site there is some interesting stuff. See my post in the Yellowstone thread for two links about earth tides.

From that same site look at this page which talks about the movement of the trace.

The inital movement shows that the earth moves toward the epicenter AND to the southeast. Therefore the earthquake was SE of Leonard. Most of South America is E of North America. The Colombian Andes are SE of Oklahoma.

Does this mean what it is saying literally?

Edit again: Oh My! This site is a mine of information. Read this:

It might seem that if the earth's surface in Oklahoma moved up and down four millimeters, that buildings would be damaged. There would be damage if the movement was rapid. However, the movement was like slowly lifting the earth over a minute or so, then lowering it as slowly. Such slow motion will not effect anything but the detection sensor of a very broadband seismometer.

This was taken from the details on this page and corroborates the statement above that the earth moves even when affected by earthquakes far away.(This particular on was in Turkey)

In it's turn this gives great credence to the theory that distant strong earthquakes affect your locality and can trigger quakes.

When you experience a big one and someone asks "Did the earth move for you Baby?" you can truthfully answer "Yes".
