Abstract
A novel earthquake sensing device is disclosed. The earthquake sensing device comprises a vertical vibrating wave sensing module, a horizontal wave sensing module and a determination module to determine the existence of an earthquake, based on, in combination, the vertical waves and the horizontal waves of an earthquake. In determining the existence of an earthquake, both the vertical waves and the horizontal waves of the earthquake are taken for consideration. Errors in the determination of earthquakes may thus be avoided.
