There was an interesting paper in Science some years back that showed a
fairly convincing correlation between certain wavelength atmospheric
disturbances (harmonic order in the 20s or so) and a seismically
detectable excitation in the Earth at the same wavelengths. Another
paper in Nature showed annual modulation of Landers aftershocks with
activity peaking in September. I think there is pay dirt there, but
I've not followed the developments...some times these claims are even
retracted after further analysis and thought. Some current paradigms on
seismicity, e.g. chaos theory, might suggest that every little factor
can have an effect on seismicity (like the butterfly effect).
