Actually, back in high school I did some statistics and found a link between tidal forces and earthquakes. Which is reasonable as the crust does flex a little.
An eclipse means the moon earth and sun are in a line which maximizes the net tidal forces. However, you can get the same impact from a lunar eclipse. It's also not much stronger than a normal full moon.
Anyway, the effect was not that strong, but I have seen it validated by other studies. The problem is say a 50% increase in odds for the next hour can be statistically significant, but the odds for a random hour are so low it's just not that useful.
PS: Best data was actually micro quakes near volcano's, but they are so tiny as to be mostly meaningless.
