I just posted my recording of the 6/16/12 Luzon quake.  I had local 
noise just prior to the quake, and missed it on the 24 hour display.

My posting shows P, pP and PP disturbances that correspond with the 
phase lines predicted by WinQuake.

The top recording is the HP filtered display.   The bottom is 
unfiltered.  I typically notice that the P wave is best observed with 
the HP filter and the Love waves with the LP filter.  This is somewhat 
at odds with the typical expectation that ALL quakes are best observed 
with heavy LP filtering.
