Horrible news coming out of Chile and my prayers are going out to all of those effected by the 8.8 earthquake. I am also wondering about our Mids out there in the Pacific. In googling mariners at sea during tsunamis, it is reported that some haven't even felt tsunamis at sea - that the wave wall is formed in shallower waters. Is this true? I would be interested in hearing from those who are better informed and even experienced in this regard to shed some light on this current event.
