Recently there has been concern that a tsunami similar to the magnitude of the Fukushima Japanese event in 2011 could hit Alaska’s coast (triggered by an earthquake).  With the strength of over 100 feet high, as many as a quarter of a million people perished from the Tsunami in Indonesia just over a half decade ago.  The subduction zone which Alaska is off of has similar characteristics as these deadly Pacific events as the geology has structures that are similar to the Shumagin  gap off the Alaska Peninsula on into SE Alaska.  The stressors tend to erupt every half a century (or slightly more).  An event to happen there would probably not hit Anchorage but there are over a hundred communities on the shore which could be overwhelmed.

If a tsunami hits, there is the home damage of flooding, immediate loss of electricity, and often smashed out windows and force exacted against load bearing walls.  How can you prepare so that when you evacuate there is less damage to deal with when you come home? If you have time after a warning or an actual earthquake that can trigger a tsunami, quickly empty the fridge and freezer into large containers you can hug off to avoid rotting.  Put plywood up on the windows facing the coast.  Take items off your deck that could roll or be pushed into windows.  Take what fuel containers you can from lawnmowers, snowblowers, snow machines, etc… for generation of power at relocation quarters and to keep it from washing up into the home through a sprung door or broken window.

Always remember that you want to throw your main breaker off and try to relocate cars behind the home with windows cracked.  All of this depends on how much time it takes you to relocate to higher ground or have to drive away.  And remember to always take a crank, solar or battery powered weather radio with you.  Be prepared, and evacuate smartly.
