It appears that the 6.2 quake in Crete on 1/22/02 was
easier to detect from 8000 km in the US with a short
period seismometer than a long period device.

Here is some data on this quake  that I got from
one of my QM-1.0 all-in-one processing boards set
to a 1Hz lowpass, and connected it to an old EV-17
seismometer that I got from Larry.

The P wave is strong but the S is undetectable.

This EV-17 detection is similar to the LCSN data from NY sensors:

As of now there is only one US long period data set on PSN

..psn
Although the P appears weaker here, this data shows the
S wave which the EV-17 was unable to detect.  This data
is from NJ.
