‘Kinkyu Jishin Sokuho’ is a emergency alert to notice the risk of earthquake. In English, it’s EEW, earthquake early warning. If government observe initial undulations of strong earthquake, they provide alert to Japanese citizens for preparation against attack of shake.

Generally, initial undulation comes few seconds earlier than shake of ground. So people can have a chance to prepare earthquake. At the moment, system is not perfect, coming earthquake earlier than alert, smaller than expected, etc. However, people evaluate the system, as Japanese has a experience of disaster many times.
