Based on the Okada model, nonlinear shallow water equation, and nested grid with high resolution, a real-time tsunami warning system of transoceanic-offshore-local is built for Wenzhou and Taizhou's coastal region of Zhejiang Province. The grid resolution of the refined layer is 900 m. The tsunami warning system includes parallel numerical calculation module, visualization module based on Python 2D library (matplotlib), and product integration module which integrates all numerical graphical products on a web page by Python. Once an earthquake occurs, the system could complete the numerical calculation, visualization processing and graphic product integration within 10 minutes. Firstly, the system has been validated by the 2011 Japan tsunami with the magnitude of Mw 9.0. Then, the extreme potential tsunami from Nankai Trough and Okinawa Trough is simulated by the system in terms of tsunami amplitude and currents. The results show that the tsunami warning system can improve the efficiency and accuracy of tsunami early warning in the coastal region, and provide a scientific basis for tsunami early warning, disaster reduction and decision supporting.
Key words: ?? earthquake tsunami??? tsunami warning system??? refined forecast??? numerical simulation???
