Wall-PIER: A Wall Clock with Procedural Instructions for Earthquake Resilience

Abstract

The Philippines, located in the Pacific Ring of Fire, is known for its countless seismic activities. The possibility of earthquakes happening is unpredictable so the government holds earthquake drills in schools for students to be aware of what to do. Still, there are some people who tend to panic and forget what to do during an earthquake. The WALL-PIER, however, extends help to people. An Arduino Nano and a Raspberry Pi 3B act as the minds of the whole system powered by a 5V2A power bank. For its capability to sense tremors caused by earthquakes, an accelerometer was connected to its main system which allows the device to give procedural instructions. Afterwards, tests with 30 trials were run on the device depending on its time response produced with 3 levels of intensities (Weak, Moderate, and Strong). Its parts’ functionality percentages were also tested. Results show that the device has 100% functionality rate. It efficiently gave out procedures and actual time. Tests that measure the response time of each level of intensity proved that the stronger the tremor, the less the time of response is. With One-Way ANOVA Analysis, it leads that there is no significant difference between the time response and level of intensity as the P-Value (0.92) > the level of significance (0.05) and the Fcalc (0.08) < the Fcrit (3.3451). This implies that each response time of the device is almost constant and is comparable to each other. The device’s response time is almost constant and is 100% functioning. The Wall-PIER could be used in schools and other high rises since it gives out instructions on what to do during an earthquake. It could also be used in commercial buildings wherein it’s internet and sound system be connected to the device for wider dissemination.
