Replying to Earthquake and its relation with snowy mountains

As you may know, Chile was hit by a major earthquake on Feb.27.
Damage to buildings were considerable, but we Chileans are strong people
and little by little we managed to get ahead and continue with our lives.
That is why, as a reporter for a ski related website, and with the winter season getting closer,
the concerns of the people regarding the safety of the practice of ski and snowboard in our mountains
are getting stronger everyday.
That's why i would like to ask you if you perhaps know about the relation between avalanche,
and earthquakes, and if you can point me in the direction where my research should be focused.
Thanks beforehand.
