The Tsunami arrived on shore about 25 minutes after the earthquake. This provided very little time for evacuation. There would be few places to escape from a 15 m wave. Unlike an earthquake, survivors will be scattered around a debris filed away from where they were. Mobile phones are unlikely to be functioning after immersion.
The latest data indicates that there is n way to predict if, when or where very large earthquakes will occur.
The Fukushima nuclear power plant was designed for an 8.2 magnitude earthquake. It survived the much larger earthquake well. Japanese nuclear power plants automatically shut down when an earthquake is detected. The Fukushima reactor had a 3m high wall around it to prevent a tsunami expected from a 8.2 earthquake. However this was over-topped by the much larger wave which damaged the emergency power supply.
The Japan Atomic Industrial Forum has detailed reports on the situation. At present it appears little widespread risk to the public. There is a literature on this field, such as: Analysis of impacts of wind integration in the Tamil Nadu grid Energy Policy, Volume 37, Issue 9, September 2009, Pages 3693-3700 Mel George, Rangan Banerjee.
Every Friday, the seismology and mathematical geophysics group holds a meeting, popularly called "Earthquake of the Week", where we discuss our research, relevant papers and weekly global seismicity.
This week happens to be of a special interest due to an unfortunate combination of great earthquake and tsunami that hit Japan, and we will most likely dedicate our entire meeting to this event with two or three presentations and discussions. ...
