In the response to major earthquake activity in the Himalayan region of Pakistan, our team has devised a shelter more resistant to earthquake forces for the indigenous population of the region. The people of the region use wood, stone, corrugated sheet metal, and sod as the primary building materials. Current construction methods involved dry stacking stone, and setting heavy roof structures resting unfastened to the walls. During earthquakes, walls are prone to collapse causing the roof to fall and crush inhabitants. To solve this problem, we designed an independent roof system supported by four corner columns made up of several bound posts. The roof is a lightweight wood frame. Relief tents can be used as a moisture barrier to cover the frame. When the tent supply is depleted, the local economy can replace this design element with a variety of woven materials. The fabric is then covered with hay or grass. Lastly, corrugated metal is placed on the top of the grass as a barrier and drainage system. The walls are separate elements designed to fall outward in an earthquake. The local people who are familiar with using these materials could easily construct this home design. With this new earthquake safe home design many lives can be saved.
