CaSPIR always take note of Solar, Lunar, Tides and Weather conditions, all of which can provide an insight into possible explanations for phenomena.

If you don't believe us that is useful data just take a look at the British Geographic Survey UK Earthquakes Page below and you will see just how many tremors there are in the UK. This website also records sonic shockwaves from Jet aircraft, sonic booms are hear fairly often, although they have travelled a long distance, they can still be heard and more importantly felt.

The NOAA Pages also give an insight into how the Suns Radiation can affect conditions on earth. Note also the use of tide tables, which are affected by the position of the sun and moon. This effect is now also suspected of having a role in earthquakes.
