Tides are caused by the difference in gravitational potential of the moon and the sun on opposite sides of the earth. Tidal forces do act on other bits of the earth than water, but this hasn't changed significantly for hundreds of millions of years. Earthquakes are caused by motions of tectonic plates, and the largest ones are subduction earthquakes where one plate is thrust below another.

Teribus and Keith are right, there is no link between tides and quakes, and the storm surge caused by a hurricane (which is not a tide, though it has the same effect) will have no effect on the motions of tectonic plates.

Microseismic events maybe, but not of any significant magnitude and not at any significant depth. The point about fracking is that material is pumped at high pressure deep underground.

What Liu, Linde and Sacks call "slow earthquakes" are movements of plates which occur over long periods of time, and are not destructive
