I watched a Horizon program last night, about volcanoes and the art of prediction. It is claimed that eruptions are preceeded by an increase in so-called "long term events", resonance phenomena in the movement of magma, and that this fact has only recently been spotted.
Now, someone would have us believe that no volcanologist has ever put the data through a fourier transform, which would show some pretty spikes, or run it through a loudspeaker at various speeds. Were this the case, then it would imply that to become a volcanologist you have to fail the Tesco intelligence test for collecting trolleys from the car park. And I don't believe that for an instant. Who is telling FIBS?
