Hi George,

I can't point you to any specific articles or books, unless there is a section on whales and dolphins in "When the Snakes Awake."

I do know there has been a lot of discussion of this link betweens whales and dolphins losing their tracking ability and subsequent earthquakes in the near vicinity. If memory serves me correctly, there was a whale lost in the SF Bay right before Loma Prieta.

Hope this helps.
