Abstract
An underground emergency shelter system for sanctuary during emergency weather conditions. A tubular entranceway allows access to the underground structure. Air intake vent stacks are positioned along with air output vent stacks to provide on top of the shell member which forms the shelter. Battery powered blowers serve to circulate air flow into and out of the shelter. Spaced stabilizing feet are provided underneath the shell member with T-shaped anchors lying on either side of the shell member to hold the shelter in place beneath the ground. Steel cable members are fitted within channels formed circumferentially around the upper portion of the shell member and are each attached to a pair of anchors thus serving to hold the shell in place. A waste holding tank is provided within the shell member along with a potable water holding tank.
