Researchers estimate total energy and local impact of the 2011 Japan tsunami – NOAA

The March 11, 2011, Japan tsunami generated about 3 petajoules of energy, according to a new NOAA study. That’s enough to power New York City for seven days or the entire country of Canada for about two and a half hours, they estimate.  The study, the first to estimate total energy of a tsunami from measurements made in real time during the tsunami propagation, was published earlier this month in the Journal of Geophysical Research – Oceans.  Read more about this here.
