An earthquake alarm device mainly includes a housing, vertical vibration detecting system, a horizontal vibration system, a battery and an alarm set. There is a spring with a specific spring coefficient k and the spring is connected to a weight. Once the earthquake happens, it will activate one of both of the vertical and the horizontal vibration detecting system so that a warning voice or voices are created. It can be activated by other magnetic or electrical method. In addition, the sensitivity of the vertical and/or the horizontal vibration detecting can be adjusted. After the earthquake is gone, it will return to its original state automatically. It will not be affected by the location. So, it is very convenient and precise in use.
