Re: [Hornlist] BBC Phil in Japan

[Valkhorn]

I side with Hans on this. People are blissfully unaware how difficult the  
Horn is (or any instrument) for that matter. So, they are blissfully unaware 
of  how difficult it is to play something consistently over and over again. 
Yet,  miss just once and they will never forget. It's sort of the opposite 
of getting  your palm read by someone, where you remember all the 'hits' - 
both of them -  and forget all the misses - hundreds of them.
 
Other instrumentalists are also sometimes blissfully unaware of what we  
deal with in horn playing - which is why I'm skeptical of any major audition  
that neglects to put someone from the section on the audition panel. 
 
But, it happens, and such is life.

I´am sure, all of them got a "terrible" vibrato when the bridge
started swinging.

o.k. no joking now. Think back two days. How was your feeling ? 
Did you notice something strange ? Did you grab for things but
fail to get them ? Did you notice a certain alertness ? Did you become 
upset by nearly everything ? Did you feel some dizziness ?

Exactly ! That is the "pre-quake-feeling". But it does not help
you to locate it in advance.

The strongest impact of brass instruments could have been
made by the trumpets of Jericho, perhaps.

But there are other impacts like the beginning of Oberon. If played
perfectly ten times in a row or more often, nobody cares, but if you 
crack it, they will talk about it even in ten thousand years & tell you

Re: [Hornlist] BBC Phil in Japan

[Jeffrey S Barker]

Sorry to be slow to reply; I read the daily digest.  What you are asking for
exists and is called earthquake intensity.  It's defined by the Modified
Mercalli Scale and is written as Roman numerals from I to XII.  Intensity
reflects the level of observed damage and is not directly related to the
physics of the earthquake source.  The best case in point is the Haiti
earthquake last year.  That earthquake was almost 100 times smaller than the
Japan earthquake (magnitude 7 compared to magnitude 8.9) but resulted in
over 222,000 deaths.  This had more to do with the rampant poverty and
corruption in Haiti than it did with the location or size of the earthquake.

Now, how can we make this horn related?  Perhaps we could start a thread on
a scale for the quality of musical sound emanating from an instrument.
Would this be a quantitative measure of the sound production of the
instrument, or a qualitative judgment by a listener in the audience?  And
how does one account for the quality, or lack thereof, of the player and the
instrument?

But you are  arguing apples versus oranges.  Hurricane scale is an indicator

EQ  intensity scales don't indicated similar things.

That all depends, too. Katrina, when it  hit the MS Gulf Coast, was  
technically only a category 3. Yet, we  all saw the damage it did. 

Even hurricane categories don't always mean  a certain amount of damage  
since they can vary based on size, where  they hit, how they hit, etc.
Charley,  
for example, exploded at  the last minute and effected a very small area. 
Andrew,  when it hit,  moved very quickly and raked the entire portion of
south 
Florida.

Re: [Hornlist] BBC Phil in Japan

[Bill Gross]

And Ike made landfall as a Category 2, however, the storm surge was more
like that of a Category 4 or 5.  I watched from afar as the Search and
Rescue Teams from Texas along with National Guard, Coast Guard and Active
Duty Helos pulled a lot of people to safety when it struck them that the
National Hurricane Center had missed the big threat.

But you are arguing apples versus oranges.  Hurricane scale is an indicator
of potential damage based mainly on wind speed and it effect on structures.
EQ intensity scales don't indicated similar things.

Then again you have to ask yourself is a hurricane a Geyer or Kruspe wrap?

That all depends, too. Katrina, when it hit the MS Gulf Coast, was

Even hurricane categories don't always mean a certain amount of damage  
since they can vary based on size, where they hit, how they hit, etc.
Charley,

Re: [Hornlist] BBC Phil in Japan

[Valkhorn]

Well I believe the reason for this is because a direct measure of energy  
doesn't exactly relate to how that energy is released. A good case in point  
involves thermonuclear exchange. I personally hope it never happens, but it 
was  a brief hobby of mine a few years ago to study how the bomb was 
developed, how  it worked, and what our arsenals meant for 'humanity'. It was 
very 
eye opening  to learn these things. 
 
It's a common misconception that if it full exchange were to happen that  
there would be one large strike for each major city, but the truth is the US 
and  USSR Arsenals numbered in the tens of thousands because they found out 
that  there would be much more damage from a 'swarm' of lesser yield weapons 
than one  large one. Additionally, they found out that there would be more 
damage from an  explosion in the air rather than on the ground. 
 
Earthquakes work the same way I suppose. Energy released is pretty much a  
direct measurement, but how it translates into what damage it causes depends 
 highly on how much energy is transferred to the surface, or if there is 
soil  liquefaction, or a resulting tsunami, the resultant ground acceleration, 
 etc.

It is probably a good tool for geophysical purposes but problematic in the

It would nice to have something that indicates scope of damage.

Re: [Hornlist] BBC Phil in Japan

[Jeffrey S Barker]

Earthquake magnitude is determined from the amplitude of ground motion as
measured on a seismograph.  In principle, energy should be proportional to
amplitude squared, just as sound intensity is proportional to pressure
squared.  However, Richter noted that the energy released by an earthquake
does not simply scale up.  A larger earthquake ruptures a larger fault, over
a larger range of depths, and over a longer time duration.  So, in defining
the magnitude scale, Richter empirically related magnitude to energy
according to: log E = 11.4 + 1.5 M (for energy in ergs).  Thus, for every
increase in magnitude by 1 unit, energy increases by 10^(1.5), or a facor of
31.6.

Re: [Hornlist] BBC Phil in Japan

[Hans Pizka]

And the more important difference between the two quakes in Christchurch was 
the location of the epicenter,
which was first about 15 - 25 kms outside town, but very near to town this time 
a month ago. 

When I was in Christchurch 2003 we stayed at the grey building (Heritage Hotel) 
you could see
next to the damaged tower of the cathedrale there. I was there playing Schumann 
op.86.

My friends live there. The historic part with the nice eateries, all gone.

Re: [Hornlist] BBC Phil in Japan

[Valkhorn]

It's about that much, yes. But, when dealing with these scales it would be  
difficult to pin down something more specific with extreme amounts of  
energy.
 
The Toba Eruption you speak of was 1 gigaton.
 
Believe it or not, the 1964 Alaskan earthquake was 90.7 gigatons.

Re: [Hornlist] BBC Phil in Japan

[William Gross]

Hans,

I've got to "hit and run" this morning.  There actually might be someone on
the list with greater knowledge than I hold.

The earthquake scale (I believe the Richter Scale has been replaced) is a
weird beast.  As I understand it's a measurement at the point where
the actaul movement happens.  Consider what happened in Christchurch, New
Zealand.  The first earthquake several months ago, that did minimal damge
was a greater magnitude than the most recent one that did considerable
damage.  The difference between the two was the first EQ happened at a much
greater depth than the second.

I hope that helps a little in clarifying.

More info on Richter scale at the link below.

William, would you kindly explain the strength of this quake by translating the 
energy
as below:   336 Mega tons   /  1,41 EJ  (Sendai quake)

One has to imagine the Sendai bay as a wonderful landscape with several

Re: [Hornlist] BBC Phil in Japan

[Valkhorn]

From:
_http://tremor.nmt.edu/faq/how.html_ (http://tremor.nmt.edu/faq/how.html) 
 
"  
A wave one millimeter (1000 microns) high on a seismogram would have a  
magnitude of 3 because 1000 is ten raised to the third power. In contrast, a  
wave ten millimeters high would have a magnitude of 4. For reasons that we 
won't  go into, a factor of 10 change in the wave height corresponds to a 
factor of 32  change in the amount of energy released during the earthquake. In 
other words, a  magnitude 7 earthquake would produce seismogram waves 10 x 
10 = 100 times as  high and release energy 32 x 32 = 1024 times as great as a 
magnitude 5  earthquake.  
The Richter scale is open-ended, meaning there is no limit to how small or  
large an earthquake might be. Due to the nature of logarithms, it is even  
possible to have earthquakes with negative magnitudes, although they are so  
small that humans would never feel them. At the other end of the spectrum, 
there  should never be an earthquake much above magnitude 9 on the Earth 
simply because  it would require a fault larger than any on the planet. The 
largest earthquake  ever recorded on Earth was a magnitude 9.5 that occurred in 
Chile in 1960,  followed in size by the 1964 Good Friday earthquake in 
Alaska (magnitude 9.2), a  magnitude 9.1 earthquake in Alaska during 1957, and 
a 
magnitude 9.0 earthquake  in Russia during 1952. Two large earthquakes, one 
a magnitude 9.0 and one a  magnitude 8.2, occurred on Dec. 26, 2004 and 
March 28, 2005, respectively, along  the same fault zone off the coast of 
Sumatra, Indonesia."
 
I hope that clears things up - but it may not.

02:46 P.M. and 11:46 P.M. in Tokyo.

But news did not talk about  yesterdays heavy quake in Yuennan SW China 
with 25 dead & over 250  injured, but CCTV9 broadcasted the Japan disaster for 
several hours in their  English program.

Somebody out there to explain the above calculation in  simplified words, 
please  ?

Re: [Hornlist] BBC Phil in Japan

[Hans Pizka]

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 ( = (101.0)(3 
/ 2)) in the energy released; a difference in magnitude of 2.0 is equivalent to 
a factor of 1000 ( = (102.0)(3 / 2) ) in the energy released.

Re: [Hornlist] BBC Phil in Japan

Japan is certainly no stranger to major Earthquakes, but this one is the  
largest Japan or the surrounding area has ever recorded I think. 
 
The Northridge Quake, although 'only' at a 6.7, had one of the fastest  
ground accelerations ever recorded - at 1.7 Gs. 
 
As you can see from here, quakes of magnitude 8.5 or higher are very rare  
indeed:

This is a major disaster for Japan, with tsunami affecting the Philippines.
Warnings have gone out to Gaum, Hawaii, Indonesia and the US West Coast.

Early reports have it as an 8.9, by comparision the Northridge EQ that his
the LA area in 1994 was a 6.7.  This equake is about 100 times more
powerful.
