In this paper efforts have been made to highlight the recent technological upgradation in the area of seismic instruments. The paper describes how seismic instruments developed in last two decades, have been clustered together to realize the modern data telemetered local seismic network array. The paper further illustrates how the recent advances in seismic sensor technology, data acquisition systems, digital communications, and computer hardware software now make it possible to design and configure "Real-time Earthquake Information Monitoring System (REIMS)". The application of REIMS, in its ultimate form, as an efficient tool to provide early warning information on the ground shaking possibly some tens of seconds before the actual arrival of seismic waves, when the earthquake is in progress, has been considered as a prime design objective. REIMS is meant to provide high quality waveform data required for detail studies of earthquake physics and structural response.
