ummm .... ok :roll:

Since you are a newfound expert on the richter scale, lets see how you do on foreign relations.

Would China report any damage to their nuclear submarines?

btw - I don't google, I just ask my brother, he was a nucular injuneer with the US Navy.

The measurements in the richter scale measures the seismic energy released from a quake. An 8.2 quake ( as measured by the richter magnitude scale) was the maximum shaking amplitude Fukushima was designed to withstand.

correction - according to company's safety measure report, they claimed that Reactor 1 and 2 were designed to withstand 7.9 but IAEA reported that its nuclear power plant was designed to withstand 7.0

The first reported measurement was 8.9 - it was then updated to a 9.0 and some reports are saying it was upgraded to a 9.1

correction - Japanese did not use Richter Scale for this one because Richter Scale can go up to 8.45-magnitude or even 9 and it's flawed. In this case, they used Shindo Scale.

Richter Scale = it measures the magnitude of earthquake based on the energy released at epicenter
Shindo Scale = it measures the intensity of earthquake at a given location

To suffice, Richter Scale suffers amplitude saturation if it goes beyond 8.0. However... for public's sake and less confusion, we used Richter Scale number for commoners to get some idea... when in fact, the scientists do not use it. They used other scaling systems to compensate for it such as Moment Magnitude Scale.

example - DEFCON System, Homeland Security Advisory System, Fujita Scale, Saffir Simpson Scale, etc.

eeerrr........... 9.0-magnitude is 1.259x more powerful than 8.9-magnitude. and 9.0-magnitude is 10x more powerful than 8.0-magnitude.

and this is a partial explanation of Richter Scale because we disregarded distance and stuff.

Just to give a example .... the difference between an 8.2 quake and an 8.9 is NOT .7 - an 8.9 quake is 5x more powerful than an 8.2 (not 7x) - the seismic energy is equated by algorithms and the energy released is measured in the thousands

Did you cheat in math? well no matter.. whether or not if you cheat in math... you still fail.

1 unit difference in Richter Scale is equal to 10x increase in intensity.
1 unit difference in Richter Scale is equal to 30x increase in energy.

Intensity and Energy are 2 different things.

wtf are you talking about?

I teach social studies. In 9th grade Geography (here in Colorado anyway), we cover physical geography...meaning that when we do earthquakes, I explain the Richter scale as simply as I can. Then they have to do the math...because they read "Richter scale" in news reports.

Like I said, when you start making "energy", "bigger", "stronger", etc, synonymous, you confuse people. So...don't do that.

Like I said...something 1000x than 8.0 would wreck the planet (as far as we know...) because that would be a 11.0 earthquake on the Richter scale. (10x10x10)

So, your an expert in nuclear reactors AND earthquakes ? ... how covenient (I guess everyone can be .. hey, its the internet after all)

Your first error in your post (and there are a lot of them) is that you are claiming I made an error that the quake was reported as an 8.9.

It was reported as an 8.9 on the richter scale. I was not using the Japanese Shindo scale. I was using the reported 8.9 Richter Scale reading.

The Richter Scale goes up to 10, not 8.45 as you are claiming (yet another error).

You are correct about the Moment Magnitude Scale (I was wondering when you would use google) as this scale is more precise.

However, you are still giving false information. That slippery slope in mathematics called Logarithms and Algorithms. 8.9 is not .7 > 8.2


PS - not to nitpick, but lets just pretend you NEVER said Fukushima's core wasn't ever going to leak.
 
What's shakin', guys? I'm sensing bad vibes in here.

er... the Japanese reported it as 8.9 and then later upgraded it to 9.0. It's very common for government & scientists to change the magnitude at later time as they receive more and more data.

USGS Release: USGS Updates Magnitude of Japan’s 2011 Tohoku Earthquake to 9.0 (3/14/2011 5:35:00 PM)
The USGS has updated the magnitude of the March 11, 2011, Tohoku earthquake in northern Honshu, Japan, to 9.0 from the previous estimate of 8.9. Independently, Japanese seismologists have also updated their estimate of the earthquake’s magnitude to 9.0. This magnitude places the earthquake as the fourth largest in the world since 1900 and the largest in Japan since modern instrumental recordings began 130 years ago.

The USGS often updates an earthquake’s magnitude following the event. Updates occur as more data become available and more time-intensive analysis is performed. There are many methods of calculating the energy release and magnitude of an earthquake. Some methods give approximate values within minutes of the earthquake, and others require more complete data sets and extensive analysis. Due to inherent uncertainties in the modeling of energy and magnitude, the results from different agencies often vary slightly. These magnitude discrepancies arise from the use of different data and techniques. For more information on why magnitudes change, see the Earthquake Hazards Program FAQ website.

FAQs - Current Earthquake Information
Q: When does the USGS update the magnitude of an earthquake?

A:

The USGS often updates an earthquake’s magnitude in the hours and sometimes days following the event. Updates occur as more data become available for analysis and more time-intensive analysis is performed. Additional updates are possible as a part of the standard procedure of assembling a final earthquake catalog.

There are physical and operational constraints on how quickly seismic data are available to the USGS. For large earthquakes, the USGS releases an initial estimate of the earthquake magnitude and location within about 20 minutes for earthquakes outside the United States. Those estimates are done using data transmitted in real time from the closest seismic stations. Some of the seismic waves used in magnitude analysis can take more than an hour to propagate around the earth and reach stations farther from the epicenter. There is no physical way to include these measurements in the initial magnitude release because the energy used in the analysis has not yet arrived at all seismic stations. Additionally, not all seismic data are delivered to the USGS in real time. Some data from contributing networks are delayed by several minutes or more, while some may arrive days after the event. As additional data become available and are processed, the earthquake magnitude and location are refined and updated.

After the initial magnitude is released, there are generally two processing points at which the magnitude of a significant earthquake may be updated. The first generally comes within a few hours of the earthquake, when the majority of the real-time data has arrived at seismic stations around the earth and more sophisticated, time- intensive, processing has been completed. The second comes within days to weeks after the event when the event is reanalyzed for inclusion in an archival earthquake catalog. At this point the USGS has received most available seismograms as well as magnitude estimates from other contributing national and international agencies. These data are assessed by the USGS and the catalog magnitude is assigned following the USGS magnitude policy. USGS Earthquake Magnitude Policy

In some regions including California, Utah, Alaska, and the Pacific Northwest, updates are also possible in the minutes following an earthquake especially when the initial, rapid magnitude release is done without human review. Magnitude updates are also sometimes made to historic earthquakes already in archival catalogs when new methods to calculate magnitude are developed and applied.

the real truth? Richter Scale has no upper limit :)

It's a trick question. You're busted! :) You DID google it after all...

not really. This formula doesn't work if it's below 3.5-magnitude. and it has its flaws. It is used in conjunction with Richter Scale and other scales to compensate for each other's limitation.

Algorithm? um.... ? Algorithm doesn't have a slippery slope in mathematics, you silly bird. It's a flowchart (or a set of rules, if you will)!

Why are you saying it was reported by the Japanese Shinto Scale but now retracting and admitting it was the Richter?

The Jiro disinfo hour is over :lol:
