Earthquake early warning systems (EEWS) based on nationwide earthquake observation networks in Japan are applied to earthquake damage mitigation in many fields. The authors have developed a real-time earthquake information (RTEI) application for school disaster prevention. This paper describes, first an EEWS demonstration test at an elementary school in Sendai and extended demonstration tests for three other elementary schools and a junior high school. Then, the transmission of RTEI using an intranet connecting schools is described, together with demonstration test using the Schools in Wide Area Networks in Miyagi Prefecture (Miyagi-SWAN), Japan. These demonstration tests were conducted as part of a government project. This paper also addresses a questionnaire investigation on EEWS applications in schools which was also conducted in the project. The experience of a real earthquake, the June 14, 2008, Iwate-Miyagi Nairiku Earthquake (M7.2), is then described. Lessons learned from the demonstration tests in schools are summarized.
