I have noticed in some Earthquakes you seem to notice
a short increase in quietness just before the impulse arrives.

Is this a real phenomena or simply a coincidence ?

Does this mean the real arrival time is
the beginning of the noticeable quiet ?

WHY THE QUIET ??
What physics would possibly muffle the noise ?

arrival of Possibly eP instead of simply P ?

Also,

What is the preferred format for a PSN files data ?
FLOAT or INTEGER
16 bit or 32 ?

My data is all 8 bit So should I expand it to
meet the new format ?

Comments ?
