Powerful quake just it Japan.

Compared to Okla's 5 something it is huge. The scale is graded exponentially, not linearly

Yes, I know how the scale works.

^^This is true.On the evening news tonight,a TU professor explained that a 5.6 is 31X more powerful than a 4.7.A 6.8 is extremely destructive.

I figured you did.
Just for general information.

Technically, due to log base 10,... its about 63.2 times greater in amplitude.

 

[dennishoddy]

Technically, due to log base 10,... its about 31.6 times greater in amplitude.

Damm you Whitey, am I going to have to debate you in Logarithmic now?

Yes... I will also require periodic debates in "e", "ln", binary base 2 and hex.

It's from the aircraft carrier sized asteroid that will be passing Earth closer than the moon tomorrow.

Good night, and good luck.

I was thinking something like the 9.0 that created the tsunami as being "huge". Just a difference in our respective definitions of the word.

Just to put it in perspective... I am about 60 miles from Sparks (rough epicenter of the 5.6), I just had some shaking and dishes rattling. No damage. A 6.0-6.9 will be destructive out to 99miles.

Not sure if dennis said it in this thread or another, Richter is based off of Log base 10 and the power release represented by richter is exponetial not linear. for instance, a 5.0 is ~31 times more powerful than a 4.0, and a 6.0 is ~63 times more powerful than a 5.0.
