There was a 9.5(or so) in Chile around 1960 and the effects from that Tsunami were felt in California and all the way across the Pacific in the Phillipines and other spots.
I also am wondering about the Easter Islands, and the Galapagos Islands and if the tsunami has hit or will hit and what kind of damage will occur there.
8.8(list of news articles) . . . probably 1,000 time more powerful that the recent Haiti quake.
