Michael Maclaughlin  asked the Naked Scientists:
   
Hi Chris,

Another question regarding the apparent increase in number of earth quakes and volcanic eruptions. Could climate change and the melting of the polar ice caps and worlds glaciers have redistributed enough of the earth's mass from high places land into the oceans to cause the earths crust to react.

Cheers
Mike

PS A great fan of your show

What do you think?

There is certainly some evidence that large dams for hydro electricity genration lead to local earthquakes

There is evidence in Iceland of annual cycles of earthquakes due to melting and re-freezing of ice and snowpacks on mountains.

You will also hear about a rebound effect where the continents have been slowly rising after the removal of weight from the glaciers during the last glacial period, over 10,000 years ago.
