<p>I have some earthquake data with an attribute field call M and has values c, h , l , m or w.</p>

<p>There is another one called Magnitude so I assume its not that.</p>

Could you show maybe a small sample of that data? Maybe the range of values would help.

This could be "Magnitude Type" where c = coda, h = helicorder, l = local, w = moment.  Though I am thrown off that m is one of the choices.

@SabreTooth that one doesn't have an 'm' option either.  I think without knowing the source of the data it's tough to say what that 'm' stands for ... I haven't found any magnitude type examples that include 'm' as one of the options.

(Asked by: username_0 on 2014-06-21)

I have some earthquake data with an attribute field call M and has values c, h , l , m or w.

There is another one called Magnitude so I assume its not that.

Any ideas what M represents and what the codes mean?

Thanks!
