4.5+ pattern on seismocam

SCECDC's seismocam has escalated to a pattern
today that often precedes a 4.5 or greater
quake in southern California. This can be
described as a large waveform display that is
3 or more times the average maximum. There also
appears a repetitive cycle of rhythm every 1.5
to 2 minutes. Formerly, a large increase on land
(for instance at station PAS)indicated an on
land quake. A large increase at an off shore
station (SNCC) indicated an off shore quake.
A regular maximum display of over 3000 at most
times at PAS or over 9000 at SNCC in the window
over extended periods of time (more than a few
hours)is the key here. Even RPV is very high. I
heard there are high wind warnings on the 5
freeway and highway 14, but don't think this is
what is causing this. It is calm here in Tarzana
anyway. The recent Oaxaca, MX and Hector Mine
quakes were preceded by this, and it is at an
even higher level now. The scary part is that
all stations are very high. Possibly this may
mean movement on multiple faults. I'll leave it
at that.

To view this for yourself go to this address:

Settings should be set at up and down and very
sensitive.
