Wow Angel!! That is a very good clean recording, and I'm amazed at the sensitivity and low noise level. Is your FMES in
a vault?
Regards,
Erich

Hi All,
Here is a jpeg of how the Siberia 7.7 (or 7.6) looked like here in
Panama on a 1 meter long FMES oriented N/S with a 24 bit digitizer.

Each line is 30 minutes long.
FMES's are easy to build and are great for tele-seismic stuff and
pretty good for the local events also.
regards,
Angel
