Last night there were two earthquakes in the  Pacific two and a half minutes 
apart. One  was:
_25-MAR-2007 00:40:02_ 
(http://www.iris.edu/cgi-bin/wilberII_EnO_page4.pl?evname=20070325_004002.7.spyder)  -20.60 169.41 7.2 35.0 VANUATU ISLANDS
and the other near Japan:
25-MAR-2007 00:41:57


37.27 136.60 6.7 5.0 NEAR WEST COAST OF HONSHU, JAPAN 
This will make the records merged but since the  Vanuatu Islands is larger, 
it should dominate. I haven't examined the records  yet but it should be 
interesting.

Hi Alan,
 
    In the UK we were 'shaking' for about 2.4 hrs! We  got traces from quakes 
going in opposite directions around the world, I suspect  twice. See Long 
Period and Very Long Period traces at 
_http://www.earthquakes.bgs.ac.uk/helicorder/heli.html_ (http://www.earthquakes.bgs.ac.uk/helicorder/heli.html)  Sorting  
it out may be more difficult!
    It would be interesting to look at the vlp  eigenmode traces.
 
    Regards,
 
    Chris Chapman
