Thousands of earthquakes occur every day in the Philippines. These earthquakes are monitored by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) using seismometers. The problem is these seismometers are expensive. The development of the country's own sensors is on hold due to a small number of researchers and lack of support. The current sensor network needs an upgrade and more sensor nodes for the study of seismology. The purpose of this study was to create a wireless, low cost and low power system that will monitor the seismic activities and will send a notification message when a strong earthquake is detected. The system uses an accelerometer as a means for measuring the seismic activity, a Zigbee for wireless communication and a GSM module for sending a notification message. The system created was placed on a Shaking Table that simulated an earthquake from magnitude of 3 up to the magnitude of 8. The test indicates that the system can recognize the strong seismic movements and will be able to last up to 90 days before the battery runs out.
