The effect of climate change on tectonic plate activity

It is disheartening to see that when people suffer from the aftermaths of a natural disaster in one part of the world (referring to the Christchurch earthquakes), people suffer from, and are fighting for their lives because of one or a few people's greediness in another part. Nearly 100 000 people have fled from Libya into Egypt and Tunisia the last week, to escape the violence of the regime (read more).

It seems like the earthquake is a natural disaster which is not possible to control, while the Libya crisis is caused by humans. But maybe also a natural disaster like an earthquake can be, at least indirectly, caused by humans?

Some scientists say that the melting of the glaciers may induce the movement of the tectonic plates. When the ice of the glaciers melt, a tremendous amount of weight is dislocated and lifted off the crust underneath. The crust will rebound and might trigger earthquakes or volcanic eruptions.

Geoscientist Allen Glazner of the University of North Carolina says in Alaska Report that

"It's unavoidable that glacial retreat will induce tectonic activity," 

This might not be the cause of the current New Zealand tectonic activity, but it's definitely worth a serious thought.
