Look at the src.psn post on  http://www.seismicnet.com/cgi-dos/event.exe 
regarding "Sneaker Waves."

Being a city boy from Northern Texas, I had never heard of "Sneaker Waves." 
Interesting information through Google.  Also, being ex-Navy, I has visions 
of U.S. Navy "Waves" wearing tennis shoes!  Wrong.

Regards,
Jerry

        To all
        Related to instrument quality- maybe. I have noticed a lot more 
microseismic activity the last few days. The background noise on my vertical 
is around +/- 300 counts @  8.7 sec  and 6.6 sec  (two narrow peaks). I 
don't remember this magnitude in years past. I'm sure it is weather related. 
I live about 200 miles east of the west coast of northern California. Anyone 
else noticed an increase in background lately? Every time I look at the 
output I think I'm looking at surface waves after an event.
