| Abstract: | On February 27 2010,06∶34 UTC,a subduction earthquake of magnitude Mw8.8 occurred at the southern-central Coastal Chile,generating a tsunami spreading to the entire Pacific Ocean.The epicenter is located at(36.1°S,72.6°W).An ocean-wide tsunami was triggered soon after the earthquake,which is recorded by tide gauge networks and Deep-ocean Assessment and Reporting of Tsunami (DART) buoys in the Pacific Ocean. The tsunami leading waves arrived in China coasts 25 hours later.The quantitative analysis of this ocean-wide tsunami was studied in detail with numerical tsunami model in this paper.We mainly focus on tsunami propagation scenarios around Chile and China's coastal areas.The simulation results fit well with the observations.Based on the simulation results,the impact of Chile tsunami on China coasts was discussed quantitatively.The evaluation of potential risk along the China coasts was given. |
