The Philippines, located in the Pacific Ring of Fire, frequently experiences earthquakes. To address this issue, two primary approaches are suggested which are the construction of buildings designed to withstand seismic activity and the implementation of earthquake early warning system. In response to this challenge. researchers have proposed the development of a device that combines both strategies This device is entitled Development of Project SMART-D: Seismic Monitoring, Alerting, and Rapid Tremor Detecting Device. This device swiftly disseminates information through its integrated buzzer and delivers notifications on applications during an earthquake. The study examined earthquake-induced angular acceleration and displacement, which affect structure integrity. Three trials with three replicates were used to calculate angular acceleration using Sieve Shaker, Human-Induced-Tremors, and Bridge-Shaking. The researchers used t-test to determine if the results differed significantly. The findings accept the null hypothesis (Ho) at 5% significance, indicating that Project SMART-D can accurately measure angular acceleration like MyShake. Researchers also used R2 to assess data variability and found a strong correlation of over 60%. Furthermore, using a single protractor, researchers verified the device's angular displacement accuracy over 6 x and y trials. Lastly, using the formula of accuracy rate with a 5% tolerance value of error, the findings were found to be accurate. The Project SMART-D is comparable to commercially available application Myshake in determining angular acceleration. Its accuracy is 97.56%, and its response time is within its expected value. Overall, it can be used in structural analyses to provide stability, and earthquake early warning system to alert people. Thus, a policy proposal must be provided to ensure its local implementation. |
