An earthquake sensing device for household is provided to reduce the total size thereof by adding an earthquake intensity sensing function to a radio receiver. A microprocessor(130) performs a predetermined control operation to control a radio frequency and volume. An earthquake sensor unit(120) and a signal amplifier unit(121) are connected with the microprocessor in order to sense an earthquake and generate an electrical signal. An emergency lamp unit(160) includes an LCD device for displaying an earthquake intensity value and outputs a lamp signal for indicating that the earthquake occurs. A button input unit(170) is connected with the microprocessor in order to receive a setting value or control a frequency. A memory unit(180) is connected with the microprocessor in order to store the setting value and the earthquake intensity value.
