RE: [emergency] Earthquake Report (A.3) Example: Questions -- typo, etc.

["Bob Wyman" <bob@wyman.us>]

On further research, it appears that Ml in the example in A.3 is an
accepted abbreviation for magnitude measured on the Richter scale. A
variety of measures for Earthquake magnitude exist. The various scales
are explained at:

The USGS data doesn't include the "Ml" since it appears to be assumed
that this is the default.
