Technology is disclosed for tsunami survival shelters. In various embodiments, a tsunami survival shelter comprises a vertical support column designed to withstand forces exerted by anticipated tsunamis and accompanying debris field; a buoyant inflatable survival life raft removably attached near a top portion of the vertical support column and capable of floating free from the vertical support column, and thereby protecting the occupants in the event of failure or overtopping of the support column; and adornments and coloring to allow the vertical support column and survival raft to blend with their surroundings by imitating trees indigenous to the area.
