Abstract

An earthquake sensor includes a base (18), a first element (22) pivotably supported on the base (18) at a first pivot location (20), and a second element (32) pivotably supported on the first element (22) at a second pivot location (30). A sensor apparatus (34) senses earthquake actuated vibration of the second element (32) and provides an output indication (41) thereof.
