I have a huge respect for sea/ocean. I have to, it is my education and some of the most important life experiences, some of them seeing my friends die, or me and my ship almost going down in storm of immense power, being formative for my outlook on life. I respect nature in general. I also was "blessed" of being in major earthquakes--so, respect for nature in general comes with the territory. Living in the Pacific Northwest--a stunningly beautiful and dangerous place--it is only natural to expect a "big one", meaning earthquake, and a tsunami, which will come. I recall when buying a house I told to our real estate agent that the house shouldn't be on the coastline, or, if close to it, it should be at the elevation of at least 60-70 feet. At least. The realtor was disappointed, he just happened to have one house "literally within a quarter of a mile from the beach" and thought that this was such a find. We flatly rejected the offer, however within our means.
Being almost 2 miles from the beach, the elevation of our house being almost 40 meters above the ocean level, we, at least, have some chances of surviving a real major tsunami which can reach a stunning height of 35-40 meters while cresting at the shoreline.
