Talk:Rohn emergency scale

This article has not yet been rated on Wikipedia's content assessment scale.

I tagged to lines for clarification. The first is "The intersection of the three dimensions provides a detailed scale for defining any emergency", where the dimensions are orthogonal. That just doesn't make sense to me. I think what is meant is that the product of the length of the vectors are a measure of the scale, but I'm not changing it myself, before I adequately understand what is meant (or preferably, see a source for it). The second line I tagged is "The scale uses the change of the number of victims over time and economical losses over time to calculate a rate of change that is of utmost importance to society". I don't really get what that means either. Is the rate of change of utmost importance to society, or does it only measure that change that is of utmost importance? Then how is utmost importance qualified? I would love to see a ref for this too. Martijn Hoekstra (talk) 18:50, 1 December 2009 (UTC)[reply]

This is a very interesting topic - I had not heard of it before. One thing that would be nice would be a computational example or two... someone with requisite knowledge, for example, could plug in numbers for the Haiti 2010 earthquake at what I would presume to be an upper end and something more localized but significant (LA riots of 1992?) to see what a more moderate to lower-level example would look like. It would make me happy, anyway, and what's more important than that? Ψν^Psi_nu 10:03, 8 March 2011 (UTC)[reply]

I've changed the mathematical notation to use roman type for English words and initialisms and the symbol for the natural logarithm function. I'd like to see a working reference for this section, though. For instance, if the asterisk denotes ordinary multiplication, the subexpressions for MaxScope reduce to ${\displaystyle {\hbox{MaxScope}}=1.2^{V}}$. And should those ratios of logs be logs of ratios?—Dah31 (talk) 02:40, 15 March 2011 (UTC)[reply]

After the introduction: "The scale is a normalized function whose variables are scope (S), topography (T), and rate of change (D), expressed as E = Emergency = f(S,T,D)" the function f is never defined! How, exactly, is one to use the values S, T and D to calculate the value of f ??

I totally agree with the above comments (although admittedly, some of it is a bit beyond me). I especially would also like to see examples but can't find anything. --MarkRoxWiki (talk) 06:59, 2 January 2014 (UTC)[reply]
