This is interesting-

For the last few days I have been seeing "packets" of low-freq waves coming
in. They last for a few minutes, fade away for 5 or 10 minutes, slowly
build up again, etc. They are in the freq range of about 6 to 10 sec per
cycle (I haven't checked the freq on Winquake yet). This is similar to the
normal swell action I see being just a block away from the ocean, but is
more regular and of a lower frequency. 

I wonder if this is from the slow quake? Has anybody else detected this? I
would be glad to capture and upload a file to the PSN website if anyone is
