EARTHQUAKE INFORMATION CENTER acts as a central role for the distribution and the usage of all data collected under the Earthquake Prediction Program. Its roles are the distribution and archiving of all observational data obtained through nation-wide network and the development and maintenance of the data distribution network. EIC also creates a database from these observational data and develops a software to analyze this database. To utilize this database for earthquake prediction researches as well as basic researches, EIC coordinates various kinds of collaborative projects among domestic and international researchers.
