I found this table revealing if specious:
Richter TNT for Seismic Example
Magnitude Energy Yield (approximate)
-1.5 6 ounces Breaking a rock on a lab table
1.0 30 pounds Large Blast at a Construction Site
1.5 320 pounds
2.0 1 ton Large Quarry or Mine Blast
2.5 4.6 tons
3.0 29 tons
3.5 73 tons
4.0 1,000 tons Small Nuclear Weapon
4.5 5,100 tons Average Tornado (total energy)
5.0 32,000 tons
5.5 80,000 tons Little Skull Mtn., NV Quake, 1992
6.0 1 million tons Double Spring Flat, NV Quake, 1994
6.5 5 million tons Northridge, CA Quake, 1994
7.0 32 million tons Hyogo-Ken Nanbu, Japan Quake, 1995;
Largest Thermonuclear Weapon
7.5 160 million tons Landers, CA Quake, 1992
8.0 1 billion tons San Francisco, CA Quake, 1906
8.5 5 billion tons Anchorage, AK Quake, 1964
9.0 32 billion tons Chilean Quake, 1960
10.0 1 trillion tons (San-Andreas type fault circling Earth)
12.0 160 trillion tons (Fault Earth in half through center,
OR Earth's daily receipt of solar
energy)
http://www.seismo.unr.edu/ftp/pub/louie/class/100/magnitude.html
With all due respect to those who compiled it, it is hard to see how
the accuracy can be maintained so evenly. But then it is probably
similar to my efforts, no more than a rule of thumb.
My stuff fits in there somewhere between the 6.5 to 8 mag quakes. A
super-typhoon will cause the same amount of input to an international
weather model run as a 7 to 7.5 quake. Give or take a few million tons
of TNT.
I liked that bit at the end about the value of the insolation for one
day. |

Nope. Not a rule of thumb. It's all in the formula just above
that chart...
logE(s) = 11.8 + 1.5M
where E(s) is energy in ergs
M is magnitude
Ergs is a unit of energy which can be converted into other
forms of energy, for example joules or megatons TNT.
Simple math(s). Well, the logarithm might be secondary school.
I've done the math several times before. I'd be glad to walk
you through it if you'd like.
For example, my calculations regarding the Sumatra quake can
be found at,
http://groups.google.com/group/sci.geo.earthquakes/browse_thread/thread/860
09267aa53cee9/66d35a57217238e7?lnk=st&q=&rnum=1#66d35a57217238e7
or if that's too long...

Gosh. What a deep and profound statement. I hope you didn't

Of course, one cannot hurt what one does not have. So I guess
that means you can't hurt yourself thinking.

To certain degree you can compare energy other large explosions
like a volcanic eruption(6), skyscaper falling down(3), solar
flare(14),
etc. |

Why do you even bother replying to me if you are no better than I?
There is a season of large quakes running at the moment, after what
has been a dearth of them. The two Japanese ones occurred
coincidentally when there was a typhoon that reached past Japan's
record books, the others are all a matter of those interesting degrees
apart from either that storm or one running in the area of Hawaii and
you think I am the fool?
They seem to circle them like some sort of a gyre if you are
interested.
That scale runs ad indefinitum with a regular increase of 2, 4, 6, 8
and you sit down with your cheesy mathematics as though it has
explained something to you of great significance.
Weather models are impossibly complex and require the finesse of
experts with decades of training, people culled from the best science
classes straight from scholl and even then can't do much better than
give a rough estimate for all the tickling the runs get.
Vulcanology as a science doesn't even exist. It is like the priest-
craft of the dark ages masquerading as Christianity. People are still
poking mountains with sticks as in biblical times and they are the
best we have.
No-one is even working on a method to explain tides and you sit there
telling me I don't think?
Put me back in you kill filters please, oh brilliant one. I am not
worthy. Either that or pull your finger out,
fool! |

If your original offer is still open would you care instewad to work
out the proximity of the recent spate of large magnitude earhtquakes
to the varios tropoical / extratropical storms also current at their
times.
Then one of us can apologise to the other. |

Because your responses are entertaining?

Do you really want me to answer that?
But seriously, ever hear the phrase "correlation does not equal
causation"? Just because two events happen in proximity spatially
and/or temporally does not mean one caused the other. Hey, I had
tuna for lunch and the sky was blue!!
Quote: They seem to circle them like some sort of a gyre if you are

’Twas brillig, and the slithy toves
Did gyre and gimble in the wabe
Quote: That scale runs ad indefinitum with a regular increase of 2, 4, 6, 8

FYI, it's "ad infinitum".
But yes, the scale is a regular progression. The amount of
energy involved in larger quakes is quite large, therefore
the scale is structured logarithmically to compress the
information into a range the majority of people, educated
or not in seismology, can understand.
It's much easier to compare to quakes by saying either mag 6
versus mag 9 than saying 6.3e20 ergs versus 1.99e25 ergs.
Or would you rather measure your car's speed in furlongs
per fornight?

"scholl"?

What do you mean "explain tides"? Didn't you go to scholl?

You've lost already. Quakes happen all year 'round. All I'd
have to show is a graph of the average number of quakes each
day for a year and you'll see a relatively flat line. That
tropical storms have seasons, ie only happen during certain
times of the year, proves lack of causation. Quakes happen
equally with and without storms.
To put it another way, explain all the quakes that happen
when there are no tropical storms?
