The cause of a quake and the trigger of a quake are two entirely differnt animals. Could the drag force created by a hurricane making landfall trigger a quake? It's plausible. I am not familiar with the dynamics of the force you are referring to, so I would have to read the research. If it slows the rotation of the Earth, then I would expect the tectonic influence to be global, not localized. Remember, the focus (point of origin) of earthquakes is typically tens to hundreds of miles underground, and energy does not propogate well through the Earth's fractured crust. Even nuclear explosions have been shown to have no effect on seismicity.
Either way, for a hurricane to trigger a quake, the portion of the fault that is triggered by such a force would have to be primed to move anyway, so is it really signifcant that it moves one day, one month, one year verses the next? Geologically speaking, no.
Another issue lies with how to prove that that a hurricane making landfall on one side of the globe triggers a quake a week later on the opposite side of the globe. How are going to gather that evidence? Remember, coincidence does not make good science.
A temporary increase or decrease in the seismicity rate is usually just that -- part of the natural variation in the Earth's or a region's seismicity.
