Where do you look to see it?

Well, what are you waiting for Muzzy, go find the lowest magnitude you can and add it to spreadsheet! So which agency has your particular favor today? Oh wait! Looks like USGS has the lowest magnitude today! Oh no! What are you going to do? Can't use their Mb of 6.0! Noooooooooooooo. Chile has 6.2 Mw. EMSC 6.3 Mw. Oh dear. What a terrible problem.

[snip]. You have obviously not studied even one bit about seismic instruments, digitizers, and telemetry in general, to be making such ludicrous remarks. Scientific calculation based upon instrumentation is scrutinized on a daily basis by other scientific peers. And that includes quake magnitudes. [snip] Just never mind. I can see this is going to be pointless. I won't confuse you with the facts, seeing as your mind is already made up...
I don't understand why people do this. If you don't know, why don't you just admit to yourself you don't know, and go study to learn more, so that you can come to a forum like this and actually have a viable conversation? [snip]
And as to the 1960 Chile quake, it is estimated from data that about 900 to 1000 km of rupture occurred to create that quake- the most powerful quake ever recorded. So if twice that amount, or 2000 km of fault ruptured at once, then what magnitude would that be, in Mw? Of course, that would be assuming you understood seismic moment, and the various magnitude types in use today. I won't hold my breath, seeing as the answer would depend on the width of the fault rupture as much as the length. But of course you knew that, right? Of course.
UPDATE: Things seemed to have quieted down pretty well on the fault, and the aftershocks seem to be diminishing in frequency and magnitude. Let's hope it keeps that up.edit on Tue Mar 18th 2014 by TrueAmerican because: (no reason given)
