Earthquake impact on (longterm) weather

I thought this was an interesting article. I did not realize that earthquakes shift the mass of the Earth (albeit a tiny fraction), can affect the axis of rotation and even change the length of the day. They can also affect the polar location of the North Pole as well as the Earth's magnetic field.

I wonder if anyone is studying what impact these changes are having, if any, on worldwide weather patterns?

In recent months, there seems to have been more severe weather out there, especially the snow storms in the east, as well as rains and flooding in various areas. I wonder if we are starting to see some of the changes to worldwide weather patterns?
