Due to the fact that Philippines is located along the Pacific ring of fire, visual inspection to assess the integrity of a structure is commonly used in the country. Other methods also exist but require destruction of a portion of the structure or may need expensive tools. Both give reasons for the proponents to think of a solution in risk reduction among structures such as buildings. In this study, a cost-efficient system will produce a solution to the time consuming, expensive and inaccurate approximation of the integrity of a structure. Using MEMS accelerometers incorporated with microcontroller capable of sending data over the internet, a structural response logger that can detect anomaly was produced. Its accuracy was evaluated by a vibration laboratory tests while its functionality such as the alarm was tested using the Government's earthquake simulator.
