Hey guys;

In Winquake

event file: 091025.105300 from GVA
When I integrate this event the ground seems
to drop at somewhere in the S or L wave and does
not return to normal ?

Does anyone understand this integrated waveform ?

It looks to me like only the DC blocker circuit
is returning the signal to its baseline.

I have seen this before but do not understand it.

In my wildest imagination I can in no other way
explain this results of the integration.

Is Arizona slowly sinking into the Earth ?
Will we have another ocean where there used to be desert ?
