		abstract={In absence of warning for earthquake, people did not prepare for incoming earthquake and incoming aftershock, that gonna need some equipment which can use to detect earthquake, that equipment can be installed in civilian buildings or government district buildings . This research discusses construction of system and SMS Gateaway for earthquake using microcontroller base, which use three vibration sensor in perceptron metode . The system consist of automation of function to activated buzzer and SMS gateway, buzzer for activate the alarm when it vibrate and SMS Gateaway for sending notification to civilian. The alarm will continuously active as long as the vibration happens and it will stop after one minute after the vibration end. The earthquake alarm testing is done by dropping of 300 g, 470 g, 780 g load. The reference that used to indicates the occurrence of earthquake is MMI (Modified Mercally Intensity). The result indicate alarm will active if number 2 and 3 sensor get the vibrate values. Sensor in each experiment could detect low intensity, medium intensity, and high intensity of earthquake}
