upgraded to 8.9

biggest (probably most devastating) ever recorded in Japanese history.

towns flattened, cars washed away to sea just like a bath tub rocked by a giant.

Streets are absolutely mad here. Millions rely on the subway to get home so are in the streets trying to get food, find toilets, etc.

So all news media are reporting Japan's earthquake to be 8000 times more powerful compared to Christchurch one.
 
Could somebody help me with a math here:
Japan  8.9
Christchurch 6.3

It is my understanding that it is log scale, so 7.3 is 10x more powerful and 8.3 100x more powerful, and 9.3 would be 1000x more powerful than Christchurch.

So where is this 8000 coming from??? what I'm missing?

From Wikipedia:
"The energy release of an earthquake, which closely correlates to its destructive power, scales with the 3⁄2 power of the shaking amplitude. Thus, a difference in magnitude of 1.0 is equivalent to a factor of 31.6 ( = (10^1.0)^(3 / 2)) in the energy released; a difference in magnitude of 2.0 is equivalent to a factor of 1000 ( = (10^2.0)^(3 / 2) ) in the energy released."

So, with a magnitude difference of 2.6, the difference in energy released is: (10^2.6)^(3 / 2) = 7,943; or about 8,000.

Hmmm. Picture #25 in that blog: who's going to be buying Japanese imported cars for a while now?

To give an idea of where the tsunami struck, the first part of this video shows a semi-rural area 5km north of Sendai Airport (which was also inundated, along with surrounding towns, as shown in other videos). View location in Google Maps.

From the 6 second mark it takes the wave 62 seconds to reach the road embankment - a distance of 360m, as measured in Google Earth. That's an average speed of 21km/h. Too fast for most people to out-run, even if you saw it coming.

Was it just good luck or did they manage to get all the planes out of  the Sendai airport??

The caption for photo #5 says: "Light planes and vehicles sit among the debris after they were swept by a tsumani that struck Sendai airport in northern Japan. (Kyodo News/Associated Press)" so it looks like the answer is no, at least not all the planes.
