Colin and Horace, This is really amazing stuff, indeed, but are you certain that the reading was not from the quake itself?
I will have to admit being a little taken aback by the fist image that your are hit with when you tune into that site... the photoresistor with the leads soldered in the wrong places. This is no time for ethnic jokes but, and the explanation is probably in there, but unfortunately that initial impression is hard to dispose of easily when the juicy material is in a language that for some illogical reason is impenetrable to this reader, especially since I can read French, Spanish and Latin to a modest degree, but have found babelfish to be... well, Babel. Must be a past-life thing... Colin, can you forward your translation of the relevant stuff? Thanks, Jones
