Hi,

I have some 'suspect' signals; but the noise level was a little to high, =
but you can see the events on =
http://www.earthquakes.bgs.ac.uk/helicorder/heli.html and check out the =
new station Elsham (short period channel).

      Thanks, Ted Channel

    Hi Ted,

        You can get broad band drumplots for the last 10 days at =
http://www.earthquakes.bgs.ac.uk/helicorder/heli.html but I don't see =
much which looks significant. The nearest station is JSA in the Channel =
Islands. I  would expect local events to show up on the 3 to 8 second =
short period traces. Note that these are VERY small quakes!=20

        Regards,
