Abstract

Earthquakes result from the sudden release of energy along fault lines within the Earth’s crust, generating seismic waves that can travel over considerable distances. Although Malaysia experiences relatively low seismic activity, the country remains vulnerable to earthquakes originating from neighboring regions, highlighting the importance of effective earthquake monitoring and early warning systems to enhance public safety and minimize potential damage. This study presents the design and implementation of a cost-effective, real-time earthquake detection system based on an SM24 geophone and a Raspberry Pi platform. The SM24 geophone, a highly sensitive transducer with a sensitivity of 28 V/(m/s), serves as the primary sensing device by converting ground vibrations into electrical signals for seismic monitoring. The Raspberry Pi performs real-time data acquisition, signal processing, and seismic event analysis, while Virtual Network Computing (VNC) functionality enables remote system access, monitoring, and maintenance. During system development, challenges related to sensor calibration, data acquisition, signal processing, and detection algorithm optimization were systematically addressed to improve measurement accuracy and operational reliability. The proposed system was extensively validated through controlled laboratory experiments using shaker-table simulations and benchmark seismic waveform data. Experimental results demonstrate that the system can accurately detect seismic events across different vibration levels while maintaining reliable real-time performance. Owing to its low cost, scalability, and ease of deployment, the proposed solution is particularly suitable for continuous seismic monitoring in resource-constrained and remote environments. Overall, the proposed system provides an efficient, accurate, and affordable approach to earthquake detection and offers significant potential for supporting early warning systems, disaster preparedness, and seismic risk mitigation in earthquake-prone regions.
