Abstract
This paper studied the utilization method of JMA earthquake early warning system for the university campus in Kusatsu city, Japan. The earthquake waves due to the assumed Tonankai earthquake, which may damage to the campus in the future, were calculated using 1-D nonlinear earthquake response analysis. The predicted waves at the campus continue more than 1 minute and its JMA seismic intensity is 5 lower. Considering the characteristics of the earthquake early warning system, the results showed that we have 30 seconds to prepare for the main shock after receiving the information. We surveyed the time spent in taking refuge from seven-story buildings, the attitude after listening to the earthquake early warning message and the danger spots in the university campus. Using these results, we proposed suitable anti-earthquake measures for the university campus by using earthquake early warning system.
