AEDS: Arduino-Based Earthquake Detector With Sms Alert System. Unpublished Research Paper. Science, Technology, Engineering, and Mathematics. Senior High School. Earthquake is an unpredictable natural phenomenon which happens suddenly and cannot stop it, but can be alerted from it late shifting. Earthquakes are a significant problem in the Philippines due to the country's location on the Pacific "Ring of Fire," a region with high seismic activity. To address the issue, the researchers built a prototype that provides early warning through Short Message Service (SMS) to the public in the event of an earthquake occurrence. This study aimed to design a system which can provide protection and preparedness for the sudden earthquakes. This study is beneficial to the community by imposing preparedness. Finding of this study revealed that the prototype can indeed identify seismic vibrations and send SMS notifications to those who
