i-jishin, an app that measures earthquakes using MEMS acceleration sensors built in mobile information terminals such as smartphones and geonavi that receives, stores, and displays seismic records on a cloud server is developed. The test results for the performance validation of the system, an example of the application to strong-motion observation of buildings, and approach of field test for local communities are introduced.
