The solar seismic alarm is a system developed to prevent population from any disaster that may occur due to a seism, which alerts hearing impaired people by means of wireless vibrating bracelets and visual alert intermittent lamps, also having a sound alert. This system also has two activation mechanisms, the first mechanism being based on a frequency receptor that receives a signal from the seismographs of the seism epicenter zone and the other being based on a pendulum sensor of automatic activation, which captures any seismic wave, thus the system being efficient and free of faults. The alarm has a rechargeable battery and solar cells for feeding the same, the battery maintains the charge up to three months without receiving power from the solar cells, thereby being practical and functional. The seismic alarm is also used for carrying out evacuation drills with an event button; in addition, this may prove the correct operation of the system.
