Abstract
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.
Highlights
Earthquake is a natural phenomenon that can occur at any time and occur naturally due to the release of energy, elastic displacement, or the collision of the earth's plates in the fault zone all at once [1]
The province of West Sumatra has a high potential for earthquake disasters because it is located between the confluence of two major continental plates and the Semangko fault [4]
This study aims to develop a distributed sensor system that can determine the magnitude and intensity of an earthquake using accelerometer and piezoelectric sensors and the MQTT protocol for data communication to activate the tsunami shelter finding system
Summary
Earthquake is a natural phenomenon that can occur at any time and occur naturally due to the release of energy, elastic displacement, or the collision of the earth's plates in the fault zone all at once [1]. The city of Padang has a tsunami early warning system This system consists of sensors off the coast that detect incoming tsunami waves. The sensors send data about the waves, which is converted into information so that people on the coast can be evacuated by sounding a siren [6]. For the evacuation process to go smoothly, the community needs to know where the nearest shelter is located. The problem is that many people do not know where the nearest tsunami shelter is and only know a few evacuation locations [7]. This leads to severe congestion when the evacuation process is underway [8]. This study aims to develop a distributed sensor system that can determine the magnitude and intensity of an earthquake using accelerometer and piezoelectric sensors and the MQTT protocol for data communication to activate the tsunami shelter finding system
