seismic events and examiones them to see if there's any correlation with asteroid movements.
Fascinating isn't it chariklo . . . thanks for the link
There is a new but growing interest in this correlation. Unfortunately it tends to be the preserve of the more sensationalist "fringe" scientists at present. Recently a man called Ken Ring (aka the moon man), made some specific earthquake predictions for Christchurch, based on lunar phases . . . and was widely debunked by mainstream geologists. Unfortunately his specific predictions failed, but a small upswing in seismic activity did occur around the time of his prediction.
When we consider the moon's effect on the oceans, it's not entirely without science. Crustal distortion owing to the moons effect is a real phenomenon and is measureable. There is little overlap between astro-physics and geology however, and scientists within each field tend to confine themselves to their respective fields and so little interactive study has been done.
Another phenomenon new to research is the occurrance of "Earthquake lights" . . . an aurora type occurrance that can sometimes appear prior to or during a major Quake . . .

Identifying the energies involved here could be the most promising discovery in predicting or providing early warnings for Earthquake occurrance. The lack of warning is what makes Earthquakes as dangerous as they are.
In all new sciences I like to keep an open mind. I like the philosophical approach of Albert Einstein in this respect . . .
To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science. Albert Einstein
