Padang City as the capital of West Sumatera Province is at high risk of earthquakes and tsunamis due to its location between two continental plates and the Semangko Fault. Currently, there are several shelters in Padang that serve as evacuation sites as a rescue location when a tsunami hits. This paper presents an earthquake detection system that uses distributed sensors to activate the shelter search system. The proposed system will activate the shelter search system when the earthquake has medium or high magnitude intensity. The earthquake identification system is achieved by calculating the Peak Ground Acceleration (PGA) value from the p-wave and s-wave using piezoelectric and accelerometer sensors. The proposed system is a distributed node sensor placed in different shelters which communicate using MQTT protocol. To evaluate the system, system for earthquake detection using Raspberry Pi, piezoelectric sensor, accelerometer MPU-6050, and Xbee for data communication have been implemented. The result shows that the system can detect the magnitude and intensity of the earthquake.
