The Gragraph is a home seismograph that warns you as an earthquake is occurring, measures the intensity, and records the data in its calendar. The verbal warnings are in Japanese, but the digital data can be easily accessed in any language. In normal mode, the Gragraph serves as a tabletop calendar/clock and a reference for past activity.
