The Earthquake Actuated Door Latch mounts outside a cabinet or beside the cabinet door. The device contains a pivoted catch assembly with a weight on one end and a door catch, or hook, on the other. The catch assembly is stable in two positions, one on each side of the cabinet door. An earth tremor causes the weight to shift out of the cocked position to the operated position (the second stable position) putting the hook where it interferes with opening of the cabinet door. Weight and hook move as a unit, minimizing delay, and an internal lock prevents rebound.
