Abstract
   The 2008 Iwate-Miyagi Inland Earthquake was not only the first case that Earthquake Early Warning (EEW) could be successfully broadcasted before the arrival of strong tremors, but also the first case that EEW was broadcasted through loudspeakers by J-ALERT system. In this research, a questionnaire survey was conducted to understand the effectiveness of EEW broadcasting by J-ALERT system in Shonai Town, Yamagata prefecture. It is verified that broadcasting by J-ALERT system is useful to convey EEW widely at the same time. However, residents’ understanding on proper response to EEW was insufficient. It is necessary to enhance residents’ capacity to take proper action after the warning. [This abstract is not included in the PDF]
