Wired: Can Hurricanes Trigger Earthquakes?
The hypothesis presented is that moving surface mass can affect the pressures on a fault zone causing it to release.
However, what is not tested is whether infiltration of water from the 2008 tropical storms into the faults could have led to thixotropy in 2010 - where the strain already on the faults was released by the addition of water. This process is already well understood and it would fit the timeline better than the mass wasting events.
