摘要：

Development and improvement of the International Tsunami Monitoring System is getting more important after the 2004 Sumatra-Off-Earthquake Tsunami diaster. Till now, tsunami monitoring system has been developed and established based on observation network of strong ground motion only. Nevertheless, earthquake vibration data may give us incorrect tsunami forecasting, for the strength of the vibration and the tsunami energy are not exactly proportional. Therefore, offshore and coastal direct tsunami-wave profile observation system should be included in the monitoring system. This paper introduces basic design of the future tsunami monitoring system using newly developed GPS buoy systems and other coastal and on-site sensors. Method of real-time tsunami data processing system is also introduced.
