A magnitude 7.0 earthquake struck the city of Kumamoto, Japan in 2016, killing 49, injuring about 3,000, and leaving tens of thousands of residents homeless. The round shape of the Styrofoam vacation homes at the ASO Farm Land Resort proved highly durable and the resort turned into an evacuation center for thousands of victims from the nearby city. The stock of the foam dome manufacturer then skyrocketed, not just due to the quake resistant properties, but also their cheap manufacturing costs, quick construction time and insulation. A dome house can be put together in just one week by a team of three people and costs about $70,000.
