My question was a serious one. Bugging in, or sheltering in place is my preference, but I realize that there may be times when I have to bug out. For me, I consider bugging out to be leaving quickly, and being gone anywhere from a few hours to a week or so. An example of a brief stay away from home might be - a chemical spill. A longer stay might be a hurricane. For your situation, not knowing the elevation of where you live, I can see where a tsunami warning must be taken seriously. If the potential wave is tall/strong enough to take out the bridges, is it tall/powerful enough to reach you? If so, and there is ample warning, bugging out (leaving until the danger passes) might be wise. If it fizzles, or is not too destructive and leaves the bridges in place - you bug out may only last a few hours or up to a day. If it is in fact a bridge killer, then you must be prepared to be away much longer.
