Abstract

Earthquake is the most dreadful phenomenon among the 5 types of most common natural disaster.The existing earthquake alert system is costly and there may be faulty detections.Therefore,a low cost Internet of Thing ( IoT ) based real time earthquake early alert system is proposed where the system could estimate the earthquake epicenter and P-wave arrival time in an area around 25 kilometers apart from 3 sensor nodes.A disaster messaging system is develop which aims to send alert information and a site recorded video to Telegram channel for validation purpose when one of the accelerometers in 3 sensor node detects acceleration exceeds threshold value of 0.05 m/s2.The time for delivering the alert message with photo and video attachment of the proposed system is calculated to check its efficiency.The map which illustrate the estimated epicenter coordinate and estimated P-wave arrival time using ThingSpeak MATLAB Visualization feature will then be sent to the Telegram channel for better understanding purpose.3 shaking tables will be built to verify the proposed system through earthquake simulation at 6 different preset epicenter locations at each sensor node.Through the experiments,the final alert warning will be sent to Telegram channel within 68.1 seconds and earns an average short period of 35 seconds respond time for immediate evacuation or other purposes before P-wave hits the destination.
