Japan Tsunami Wave height animation across the Pacific ocean

This National Oceanic and Atmospheric Administration (NOAA) image released on March 11, 2011 shows model runs from the Center for Tsunami Research at the NOAA Pacific Marine Environmental Laboratory showing the expected wave heights of the tsunami as it travels across the Pacific basin. The largest wave heights are expected near the earthquake epicenter off Japan. The wave will decrease in height as it travels across the deep Pacific but grow taller as it nears coastal areas. In general, as the energy of the wave decreases with distance, the near shore heights will also decrease (e.g., coastal Hawaii will not expect heights of that encountered in coastal Japan). Tsunami waves rolled thousands of miles across the Pacific Ocean after a massive earthquake off Japan and washed ashore in Hawaii early March 11. (NOAA)
We all have seen the huge devestion by the Tusnami and pictures are burned into our heads.
Now Satellite Images for Japan after March 11 are available. The New York Times has created a collection of "before-after" comparisons of selected location within the area affected by the big Japan quake. You can use a sider to see the damage done by the quake and tsunami:
