Abstract: In December 26, 2004 Indian Ocean Tsunami is considered to be a ＂global geophysical incident＂. According to the data, picture and video downloaded from the internet, we make calculations and analysis of some physical phenomena in tsunami and design a lesson ＂The Physics of Tsunami＂ for students as part of the project ＂How to study physics in the age of information＂.

Key words: tsunami, physics, vibration, wave
