Abstract: The present invention relates to an earthquake alarm that functions as an awakening and early warning mechanism which provides an audio and visual warning to a possible earthquake. The device is comprised of a free-standing arm which rests against an adjustable rod which can be manipulated to make the arm more or less sensitive to vibrations, The arm, which is pivotally mounted within a case, swings downwardly through a slot in the case when vibrations comparable to the vibrations of an earthquake cause the arm to be dislodged from its upright position. The arm is entrapped between two tabs that extend outwardly from a rotatably attached beam. The beam comprises a third tab which is secured against one distal end of a rocker arm, the opposite distal end of the rocker arm being engaged in the extended teeth of a spring loaded wheel.
