Don't build "nuclear power plants" near cities

.......or near "seismic zones", and ensure area is with a low density population in a 20km radius. Make sure a Brigade of Marine is based nearby for "security" and "manpower" to help in evacuation!

cheerios!

Do you know the seismic intensity (Chinese scale) of the Great Wenchuan quake which had mag. 8,0 on the Richter scale and shindo 7 on the Japan. scale?

I did the comparison on Seismic intensity scale between China and Japan.
And I think the Great Wenchuan equake is much more devastated than the earquake nearby the coast of Japan.
You can compare with the distance from the epicenter to the cities and towns.

.
The Seismic intensity 11: in the center of Wenchuan Earthquake
The Seismic intensity 10: about 3,144 Sq. Kilometers.
The Seismic intensity 9: about 7,738 Sq. Kilometers.

(Building codes in China)
Almost all of building in urban area of Chengu, Sichuan province, are safe in the Seismic Intensity 7.

I guess that the leaking accidents of nuclear power reactors was caused not directly by the earthquake but by the following tsunami.
I am doing the search.

Early-Warning system

An Early Warning:

The main earthquake was preceded by a number of large foreshocks, beginning with a 7.2Mw event on 2011-3-9. Residents of Tokyo likely had about 80 seconds of warning before the devastating quake in 2011-3-11 after striking 373 kilometers away, thanks to a new early warning system.

source: ww w.technologyreview.com/computing/35090/?p1=A3&a=f

e.g. It takes 2 minutes for a damaing earthquake arriving at the City X from the epicenter. but It takes 0.5 minutes for one type of radio waves detected by sensors and it takes 0.5 minutes to broadcast through TV and other networks in transportion vehicles such as high-speed trains and in many other sectors such as nuclear power plants. And then there is 1 minutes for people to escape and to do the preparations.


+++++++++

The director of Seismological Bureau of China, also a Congress member, Chen Jianmin said, No one can predict a coming earquake except a God. And China don't have such an earthquake early-warning system of Japan, but plan to build a little in trial area.

One Chinese academician, also a Congress member, Chen Yuntai said, China shouldn't stop the research on Earthquake Forecast before the difficulties. It's not a question involving political decisions.

Energy

Energy

2004 Sumatran earthquake, Magnitude: 9.1, in Indian Ocearn off the coast of Indonesia killed 230,000 people.

This earthquake off the coast of Japan released a surface energy nearly doubled the Sumatran.
The total energy released was slightly less than the Sumatran.

"If we could only harness the [surface] energy from this earthquake, it would power Los Angles for an entire year," USGS director Marcia McNutt said in an interview. The total energy released (Mw) was more than 200,000 times the surface energy.
