Abstract
A seismic sensor may include a simple earthquake detection mode in which measured acceleration data is not saved, and which mode is continued in a case in which the measured acceleration is equal to or less than a predetermined first threshold value. An earthquake detection mode may further be included in which the measured acceleration data is saved, and which mode is continued in a case in which the acceleration measured in the simple earthquake detection mode is greater than the first threshold value and equal to or less than a second threshold value that is greater than the first threshold value. An earthquake measurement mode may further be included in which the acceleration data and a spectrum intensity (SI) value are measured and saved, and which mode is continued in a case in which the acceleration measured in the earthquake detection mode is greater than the second threshold value.
