Abstract

PURPOSE: To provide an apparatus for detecting acceleration level, in which liquid is filled in a space defined between inner and outer cylindrical bodies, and vertical motion of the liquid caused by its intertial force is detected by a plurality of detector electrodes, whereby directivity in detecting earthquake is removed, and highly accurate detection of earthquake is attained inspite of simpleness in structure.
