it seems to be getting stormy in the seas around the UK.  In the last 
few hours my seismometer has started jumping up and down, as it were.  
Looking at the BGS graph, 
http://www.earthquakes.bgs.ac.uk/helicorder/heli_dir_vhz/LRW_VHZ_GB_00.2009110700.gif 
,  it's around a 12 second period and a longer period of around 10 
minutes.  Mine shows both of these components too.
