Hi I was just wondering if there are any correlations between volcanic gases
and eruptions? If theres an increase in volcanic gases, does that means an
eruption can occur? Or should you monitor just seismic events around the
Volcano?

says the 1994 Northridge quake was:
6.70000000000000017764
I didn't know they were measured to that precision.

There was a 3.2 today near Joshua Tree...

This is very close to the location of the 6.1 which
occured on April 22, 1992, which spawned over 6000

Thanks to everyone who send me information on the sources of fault maps
online.  The most useful ones for my particular purposes do indeed seem to
be those of  the countries involved, and though my Spanish is not good, I
can manage enough to understand the "pictures."

From the USGS list :

The screw has been removed from my right leg.
No pain.

A medical transcription friend of mine who lives in the Olympia-Tacoma
area and has probably a Discovery Channel-level of knowledge about
geology asked me what I could tell her about fault line activity off
the Washington coast.  Her cousin apparently told her to watch out and

We have discussion of 'earthquake weather', but what would
you make of this unusual volcanic activity?

Quite a few strong earthquake warning type signals were detected on August
8, 2006.

Can anyone point me to some sites where I might be able to find fault lines
delineated on maps in a fairly clear way?  I am particularly interested in
places like Mexico, Peru, Chile, where there are many different faults ,
some also offshore, if the seismic record is to be ...

I have been connecting this type of info:

Still learning how to read seismographs.
Can someone tell me if this pattern is just wind affecting the
seismographs or something else?

Here's a graph from the National Geographic Web site about the July
2006 quake in Java:
"In this case, initial reports said that yesterday's 7.7 magnitude
quake had a 7.2 magnitude. It might seem like a small difference, but
