Anonymous Coward | about 3 years ago | (#35745602)

For ref, 'cos I was wondering, "shindo" [wikipedia.org] is a japanese earthquake scale, not directly comparable to the richter [wikipedia.org] scale (or the "moment magnitude" [wikipedia.org] scale often mislabelled as richter in the media) - shindo is for various points on the earth's surface, richter for overall energy of quake.

I've been having the same problem. Found it works to double-right-click (to open the context menu; single right click doesn't seem to work) and select "open in new tab", but pretty ridiculous. Even worse than before, when control-clicking to open a link in a new window just expand parent threads, often causing you to have to hunt all over the place to find the comment you were reading.

7.4 versus 9.0 (1)

goombah99 (560566) | about 3 years ago | (#35745312)

the richter scale is logarithmic so a 9 is something like 30 times larger in energy than a 7.4. On the other hand the march quake was initially rated as a 7.1 scale quake then updated later to 9.

Re:7.4 versus 9.0 (1)

Nick Ives (317) | about 3 years ago | (#35745374)

On the Richter Scale each whole number represents an order of magnitude difference in energy, so a 9 is 100 times more powerful than a 7.

Anonymous Coward | about 3 years ago | (#35745506)

On the Richter Scale each whole number represents an order of magnitude difference in energy, so a 9 is 100 times more powerful than a 7.

Yes, it is also 10 times larger than an 8, and 30 times larger than a 7.4.

 

Re:7.4 versus 9.0 (0)

Anonymous Coward | about 3 years ago | (#35745562)

And 7.4 is between 7 (a 9 would be 100times as powerful) and 8 (a 9 would be 10 times as powerful). So a 9 is 10 to 100 times as powerful as a 7.4. 30 is in that range.

Re:7.4 versus 9.0 (1)

MarkGriz (520778) | about 3 years ago | (#35745600)

"so a 9 is 100 times more powerful than a 7"

Yes, but a 9 is only about 30x more powerful than a 7.4, as the parent stated.

Actually it's closer to 40: 10^(9-7.4) = 39.8

Re:7.4 versus 9.0 (4, Informative)

Kentari (1265084) | about 3 years ago | (#35745476)

One step in magnitude means a factor 10 increase in ground displacement. In energy this is about a factor 30 per magnitude. A 7.0 packs about 900 times less energy than a 9.0. The new earthquake has already been revised to 7.1.

Re:2m high tsunami (1)

AmiMoJo (196126) | about 3 years ago | (#35744930)

Additional: only in Miyagi, elsewhere the tsunami is approx 0.5m. Fukushima Dai-ichi nuclear plant should not be affected by the wave, although obviously there is still the quake to worry about...

fredan (54788) | about 3 years ago | (#35744910)

how's the time schedule for the trains in Japan?

Re:trains (4, Interesting)

antifoidulus (807088) | about 3 years ago | (#35745136)

Most are already offline, it happened at 11:30 there, the shinkansen have probably almost all stopped, most regional services in the area probably weren't running at any real capacity anyway, so I doubt they would be running there. It was far enough away from Tokyo that I doubt any of the metros were really affected.

FWIW I was riding on the shinkansen(headed to Germany for a bit since I didn't have water and food at my place :P) when a 6.1 struck Shizuoka. I have to hand it to the designers and operators of those cars, they handled it really well. You could actually barely feel anything on the car, but all of a sudden the lights went out and the train came to a sudden, but not abrupt stop since we lost all power. No derailing, no injuries.

7.4 != 9.2 Not even close. (3, Informative)

140Mandak262Jamuna (970587) | about 3 years ago | (#35744928)

The scales are logarithmic. 7.4 earthquake is about 150 times less powerful than a 9.2

Re:7.4 != 9.2 Not even close. (4, Informative)

140Mandak262Jamuna (970587) | about 3 years ago | (#35744978)

The correct ratio seems to be 31 ^ ( 9.2 - 7.4 ) = 483. So this earthquake would be considered a moderate one, about 500 times less powerful than the 9.2 that stuck a few weeks ago.

Re:7.4 != 9.2 Not even close. (0)

Anonymous Coward | about 3 years ago | (#35745520)

moderate is 5-6
7 is major (according to the Richter scale - moderate compared to 3/11)

Re:7.4 != 9.2 Not even close. (2)

gilleain (1310105) | about 3 years ago | (#35745618)

There seems to be some sort of increase in the size of the slashdot commenter estimates of earthquake power ratios. First commenter said 30 times, then 100, then 150, now 500. Is there a logarithmic function to describe this increase in accuracy?

Answer to non existent question (0)

Anonymous Coward | about 3 years ago | (#35744992)

No one claimed they were close in power. 7.4 is still a strong earthquake and can still generate a damaging tsunami, especially in nearby areas.

Re:7.4 != 9.2 Not even close. (0)

Richters scale is not a log10 scale, so it's (10^1.8)^(3/2) ~= 500 times less powerful.

Re:7.4 != 9.2 Not even close. (1)

kabloom (755503) | about 3 years ago | (#35745276)

If they're using a logarithmic scale, there must be a reason why the logarithmic scale makes more sense. Maybe it's because the damage or perceived power scales logarithmically with the energy of the quake?

Re:7.4 != 9.2 Not even close. (1)

_0xd0ad (1974778) | about 3 years ago | (#35745444)

It's probably some sort of polynomial relation - energy being converted into motion of land mass in 3D, causing both horizontal and vertical motion, and the actual damage being related in some other polynomial way to the intensity of the shaking (complex, because you get shear forces in the horizontal combined with tensile and compressive forces in the vertical, and building materials act very differently under shear/compression/tension). And of course not to mention the fact that the damage is greatly dependent on how well the stuff was engineered in the first place. How well or poorly the logarithmic scale represents that complex relationship is sort of anyone's guess.

Re:7.4 != 9.2 Not even close. (1)

zevans (101778) | about 3 years ago | (#35745578)

I've been meaning to ask this for a while: is this somehow deduced at the epicentre or does it reflect the level of damage / energy transferred / work done over some wider area?

Is a 7.4 in one city likely to cause the same problems as a 7.4 in another? (Say one on clay and one on basalt?)

Re:7.4 != 9.2 Not even close. (2)

pclminion (145572) | about 3 years ago | (#35745398)

So you're talking about blowing up a Volkswagon with a cluster bomb instead of a nuclear warhead. The car is still destroyed afterward. If the 7.4 had happened without a preceding 9.2 people would be talking about the 6.6 aftershocks being "not even close" to the 7.4... People, all of these are really big earthquakes.

Re:7.4 != 9.2 Not even close. (0)

Anonymous Coward | about 3 years ago | (#35745402)

Make that 7.1, according to the USGS.

Re:7.4 != 9.2 Not even close. (1)

Anonymous Coward | about 3 years ago | (#35745548)

It sort of depends on what you're measuring when using vague terms like "powerful": maximum ground acceleration, averaged ground acceleration and duration, maximum displacement (instrumental or in the fault plane), total energy released, etc. There are all sorts of details when trying to compare earthquakes. For energy released, the relationship is 10^1.5 or ~32x for each Richter magnitude step, although Richter magnitude isn't used as much anymore. Usually scientists use moment magnitude [wikipedia.org] these days, which has the same relationship to energy. It makes sense that energy would equate to what you feel and how much damage occurs, but there are additional effects depending on the exact way the ground is displaced, what happens as the waves propagate from the focus to the place you are experiencing the quake, duration, frequency content, ground properties, etc.

But by any qualitative measure anything over 7 (on either scale) is a big, potentially-damaging quake. Fortunately this one was off the coast like before, and the effects diminish with distance, so the cities in Japan won't experience as severe effects as the magnitude would imply if it were directly beneath the city. To put things in perspective, the 1995 Kobe [wikipedia.org] earthquake was "only" a 6.8 on the moment magnitude scale, and "only" 7.3 on the JMA scale -- i.e. smaller than this aftershock. Yet in the 1995 quake more than 6000 people were killed. So, yeah, this is a *big* earthquake, but further away from where people are living, thank goodness. That also puts the previous 8.9-9.2 quake in perspective (i.e.: it was FREAKING HUGE).

Where did 9.2 come from? (0)

Anonymous Coward | about 3 years ago | (#35745554)

I only heard 9.0 for the Japan earthquake. Did they officially upgrade it? If so, please update the wikipedia page.
