The earthquake early warning system (EEWS) has been gradually developed from scientific hypothesis into real disaster prevention practice for the past 30 years. This paper summarizes the worldwide EEWS development and its constructing divergence in different time periods. Moreover, an introduction of the use of MEMS (Microeletro Mechanical Systems) and smartphone by seismologist and engineers as a new means of earthquake early warning is given. Not only the space for EEWS development but also more information about EEWS time nodes is analyzed in this paper. Finally, the relation between EEWS and real-time seismology is discussed.
