Hi all

Today I did detect the mb5.9 SAKHALIN ISLAND, RUSSIA earthquake. I don't
see the p and s wave in the trace, however when I check the fft window I
can cleary see the earthquake in the lower frequancyes as expected. I
find this unusual, but it might not be that becose I am using 4.5Hz
geophone. The question that I am wondering about, is this the earthquake
or just noise ?

Regards.
