This article discusses a wearable device designed to aid dogs in predicting earthquakes. The device, created by researchers at the University of Massachusetts Amherst, monitors the behavior of dogs and collects data on their movements and heart rates. The researchers believe that dogs can sense impending earthquakes due to their heightened senses and ability to detect subtle changes in the environment. By analyzing the data collected by the wearable device, the researchers hope to identify patterns that could indicate an imminent earthquake. The device is still in the early stages of development, but the researchers are optimistic about its potential to help save lives by providing early warning systems for earthquakes. The article also mentions that dogs have been used for earthquake prediction in the past, but the wearable device aims to provide a more scientific and reliable method for monitoring their behavior.
