Abstract
The Earthquake Motion Detector Alarm consists of a pendulum hanging within a sensor ring. At the instant of earth movement, the pendulum weight will make contact with the sensor ring setting off an audio alarm and floodlamp. The magnetized sensor ring can be adjusted so the detector can be installed to function on all vertical walls by positioning the pendulum weight within the ring.
