Apart from the obvious reason, tectonic plate move when there is a fluctuation or changes in sub-surface pressure. The pressure is induce by surface condition, like weather and such. Because human have made so much damage to the environment, the earth is simply trying to recover, in other word, behave in a manner so that our earth will be more livable.

The tropical storm, is normally cause by the different pressure and temperature on different part of earth due to our unique rotation and orbit. Anyway, human has done enough to disrupt this and it cause a surge and high differential weather condition across the globe, which eventually create a very large storm.

Every scientists know what cause earthquake, but nobody can really tell how and why it happen.... Some environmentalist believe it all have to do with us, though nobody would admit it, especially the heavy industry sector.
