Designed by students from Sweden's Umeå Institute of Design, the Terra earthquake detector is a minimal, low-cost earthquake alarm that serves as a source of calm during non-destructive incidents. Crafted with residents of the Ring of Fire in mind, the device expertly blends into people's homes and is affordable enough for lower income communities to access. According to the makers, the Terra earthquake detector "increases awareness and reduces panic in countries vulnerable to earthquakes."

The device works by responding to an earthquake's non-destructive primary waves, which generally travel at a higher velocity and can be detected a minute before the destructive secondary waves. After these waves are detected and sent out by seismographic institutions, the Terra earthquake detector will warn people of its estimated arrival and anticipated strength.
